-Memory Attribute Aliasing on IA-64
-==================================
-
-Bjorn Helgaas <bjorn.helgaas@hp.com>
-
-May 4, 2006
-
-
-Memory Attributes
-=================
-
-    Itanium supports several attributes for virtual memory references.
-    The attribute is part of the virtual translation, i.e., it is
-    contained in the TLB entry.  The ones of most interest to the Linux
-    kernel are:
-
-	==		======================
-        WB		Write-back (cacheable)
-	UC		Uncacheable
-	WC		Write-coalescing
-	==		======================
-
-    System memory typically uses the WB attribute.  The UC attribute is
-    used for memory-mapped I/O devices.  The WC attribute is uncacheable
-    like UC is, but writes may be delayed and combined to increase
-    performance for things like frame buffers.
-
-    The Itanium architecture requires that we avoid accessing the same
-    page with both a cacheable mapping and an uncacheable mapping[1].
-
-    The design of the chipset determines which attributes are supported
-    on which regions of the address space.  For example, some chipsets
-    support either WB or UC access to main memory, while others support
-    only WB access.
-
-Memory Map
-==========
-
-    Platform firmware describes the physical memory map and the
-    supported attributes for each region.  At boot-time, the kernel uses
-    the EFI GetMemoryMap() interface.  ACPI can also describe memory
-    devices and the attributes they support, but Linux/ia64 currently
-    doesn't use this information.
-
-    The kernel uses the efi_memmap table returned from GetMemoryMap() to
-    learn the attributes supported by each region of physical address
-    space.  Unfortunately, this table does not completely describe the
-    address space because some machines omit some or all of the MMIO
-    regions from the map.
-
-    The kernel maintains another table, kern_memmap, which describes the
-    memory Linux is actually using and the attribute for each region.
-    This contains only system memory; it does not contain MMIO space.
-
-    The kern_memmap table typically contains only a subset of the system
-    memory described by the efi_memmap.  Linux/ia64 can't use all memory
-    in the system because of constraints imposed by the identity mapping
-    scheme.
-
-    The efi_memmap table is preserved unmodified because the original
-    boot-time information is required for kexec.
-
-Kernel Identity Mappings
-========================
-
-    Linux/ia64 identity mappings are done with large pages, currently
-    either 16MB or 64MB, referred to as "granules."  Cacheable mappings
-    are speculative[2], so the processor can read any location in the
-    page at any time, independent of the programmer's intentions.  This
-    means that to avoid attribute aliasing, Linux can create a cacheable
-    identity mapping only when the entire granule supports cacheable
-    access.
-
-    Therefore, kern_memmap contains only full granule-sized regions that
-    can referenced safely by an identity mapping.
-
-    Uncacheable mappings are not speculative, so the processor will
-    generate UC accesses only to locations explicitly referenced by
-    software.  This allows UC identity mappings to cover granules that
-    are only partially populated, or populated with a combination of UC
-    and WB regions.
-
-User Mappings
-=============
-
-    User mappings are typically done with 16K or 64K pages.  The smaller
-    page size allows more flexibility because only 16K or 64K has to be
-    homogeneous with respect to memory attributes.
-
-Potential Attribute Aliasing Cases
-==================================
-
-    There are several ways the kernel creates new mappings:
-
-mmap of /dev/mem
-----------------
-
-	This uses remap_pfn_range(), which creates user mappings.  These
-	mappings may be either WB or UC.  If the region being mapped
-	happens to be in kern_memmap, meaning that it may also be mapped
-	by a kernel identity mapping, the user mapping must use the same
-	attribute as the kernel mapping.
-
-	If the region is not in kern_memmap, the user mapping should use
-	an attribute reported as being supported in the EFI memory map.
-
-	Since the EFI memory map does not describe MMIO on some
-	machines, this should use an uncacheable mapping as a fallback.
-
-mmap of /sys/class/pci_bus/.../legacy_mem
------------------------------------------
-
-	This is very similar to mmap of /dev/mem, except that legacy_mem
-	only allows mmap of the one megabyte "legacy MMIO" area for a
-	specific PCI bus.  Typically this is the first megabyte of
-	physical address space, but it may be different on machines with
-	several VGA devices.
-
-	"X" uses this to access VGA frame buffers.  Using legacy_mem
-	rather than /dev/mem allows multiple instances of X to talk to
-	different VGA cards.
-
-	The /dev/mem mmap constraints apply.
-
-mmap of /proc/bus/pci/.../??.?
-------------------------------
-
-	This is an MMIO mmap of PCI functions, which additionally may or
-	may not be requested as using the WC attribute.
-
-	If WC is requested, and the region in kern_memmap is either WC
-	or UC, and the EFI memory map designates the region as WC, then
-	the WC mapping is allowed.
-
-	Otherwise, the user mapping must use the same attribute as the
-	kernel mapping.
-
-read/write of /dev/mem
-----------------------
-
-	This uses copy_from_user(), which implicitly uses a kernel
-	identity mapping.  This is obviously safe for things in
-	kern_memmap.
-
-	There may be corner cases of things that are not in kern_memmap,
-	but could be accessed this way.  For example, registers in MMIO
-	space are not in kern_memmap, but could be accessed with a UC
-	mapping.  This would not cause attribute aliasing.  But
-	registers typically can be accessed only with four-byte or
-	eight-byte accesses, and the copy_from_user() path doesn't allow
-	any control over the access size, so this would be dangerous.
-
-ioremap()
----------
-
-	This returns a mapping for use inside the kernel.
-
-	If the region is in kern_memmap, we should use the attribute
-	specified there.
-
-	If the EFI memory map reports that the entire granule supports
-	WB, we should use that (granules that are partially reserved
-	or occupied by firmware do not appear in kern_memmap).
-
-	If the granule contains non-WB memory, but we can cover the
-	region safely with kernel page table mappings, we can use
-	ioremap_page_range() as most other architectures do.
-
-	Failing all of the above, we have to fall back to a UC mapping.
-
-Past Problem Cases
-==================
-
-mmap of various MMIO regions from /dev/mem by "X" on Intel platforms
---------------------------------------------------------------------
-
-      The EFI memory map may not report these MMIO regions.
-
-      These must be allowed so that X will work.  This means that
-      when the EFI memory map is incomplete, every /dev/mem mmap must
-      succeed.  It may create either WB or UC user mappings, depending
-      on whether the region is in kern_memmap or the EFI memory map.
-
-mmap of 0x0-0x9FFFF /dev/mem by "hwinfo" on HP sx1000 with VGA enabled
-----------------------------------------------------------------------
-
-      The EFI memory map reports the following attributes:
-
-        =============== ======= ==================
-        0x00000-0x9FFFF WB only
-        0xA0000-0xBFFFF UC only (VGA frame buffer)
-        0xC0000-0xFFFFF WB only
-        =============== ======= ==================
-
-      This mmap is done with user pages, not kernel identity mappings,
-      so it is safe to use WB mappings.
-
-      The kernel VGA driver may ioremap the VGA frame buffer at 0xA0000,
-      which uses a granule-sized UC mapping.  This granule will cover some
-      WB-only memory, but since UC is non-speculative, the processor will
-      never generate an uncacheable reference to the WB-only areas unless
-      the driver explicitly touches them.
-
-mmap of 0x0-0xFFFFF legacy_mem by "X"
--------------------------------------
-
-      If the EFI memory map reports that the entire range supports the
-      same attributes, we can allow the mmap (and we will prefer WB if
-      supported, as is the case with HP sx[12]000 machines with VGA
-      disabled).
-
-      If EFI reports the range as partly WB and partly UC (as on sx[12]000
-      machines with VGA enabled), we must fail the mmap because there's no
-      safe attribute to use.
-
-      If EFI reports some of the range but not all (as on Intel firmware
-      that doesn't report the VGA frame buffer at all), we should fail the
-      mmap and force the user to map just the specific region of interest.
-
-mmap of 0xA0000-0xBFFFF legacy_mem by "X" on HP sx1000 with VGA disabled
-------------------------------------------------------------------------
-
-      The EFI memory map reports the following attributes::
-
-        0x00000-0xFFFFF WB only (no VGA MMIO hole)
-
-      This is a special case of the previous case, and the mmap should
-      fail for the same reason as above.
-
-read of /sys/devices/.../rom
-----------------------------
-
-      For VGA devices, this may cause an ioremap() of 0xC0000.  This
-      used to be done with a UC mapping, because the VGA frame buffer
-      at 0xA0000 prevents use of a WB granule.  The UC mapping causes
-      an MCA on HP sx[12]000 chipsets.
-
-      We should use WB page table mappings to avoid covering the VGA
-      frame buffer.

-==========================
-EFI Real Time Clock driver
-==========================
-
-S. Eranian <eranian@hpl.hp.com>
-
-March 2000
-
-1. Introduction
-===============
-
-This document describes the efirtc.c driver has provided for
-the IA-64 platform.
-
-The purpose of this driver is to supply an API for kernel and user applications
-to get access to the Time Service offered by EFI version 0.92.
-
-EFI provides 4 calls one can make once the OS is booted: GetTime(),
-SetTime(), GetWakeupTime(), SetWakeupTime() which are all supported by this
-driver. We describe those calls as well the design of the driver in the
-following sections.
-
-2. Design Decisions
-===================
-
-The original ideas was to provide a very simple driver to get access to,
-at first, the time of day service. This is required in order to access, in a
-portable way, the CMOS clock. A program like /sbin/hwclock uses such a clock
-to initialize the system view of the time during boot.
-
-Because we wanted to minimize the impact on existing user-level apps using
-the CMOS clock, we decided to expose an API that was very similar to the one
-used today with the legacy RTC driver (driver/char/rtc.c). However, because
-EFI provides a simpler services, not all ioctl() are available. Also
-new ioctl()s have been introduced for things that EFI provides but not the
-legacy.
-
-EFI uses a slightly different way of representing the time, noticeably
-the reference date is different. Year is the using the full 4-digit format.
-The Epoch is January 1st 1998. For backward compatibility reasons we don't
-expose this new way of representing time. Instead we use something very
-similar to the struct tm, i.e. struct rtc_time, as used by hwclock.
-One of the reasons for doing it this way is to allow for EFI to still evolve
-without necessarily impacting any of the user applications. The decoupling
-enables flexibility and permits writing wrapper code is ncase things change.
-
-The driver exposes two interfaces, one via the device file and a set of
-ioctl()s. The other is read-only via the /proc filesystem.
-
-As of today we don't offer a /proc/sys interface.
-
-To allow for a uniform interface between the legacy RTC and EFI time service,
-we have created the include/linux/rtc.h header file to contain only the
-"public" API of the two drivers.  The specifics of the legacy RTC are still
-in include/linux/mc146818rtc.h.
-
-
-3. Time of day service
-======================
-
-The part of the driver gives access to the time of day service of EFI.
-Two ioctl()s, compatible with the legacy RTC calls:
-
-	Read the CMOS clock::
-
-		ioctl(d, RTC_RD_TIME, &rtc);
-
-	Write the CMOS clock::
-
-		ioctl(d, RTC_SET_TIME, &rtc);
-
-The rtc is a pointer to a data structure defined in rtc.h which is close
-to a struct tm::
-
-  struct rtc_time {
-          int tm_sec;
-          int tm_min;
-          int tm_hour;
-          int tm_mday;
-          int tm_mon;
-          int tm_year;
-          int tm_wday;
-          int tm_yday;
-          int tm_isdst;
-  };
-
-The driver takes care of converting back an forth between the EFI time and
-this format.
-
-Those two ioctl()s can be exercised with the hwclock command:
-
-For reading::
-
-	# /sbin/hwclock --show
-	Mon Mar  6 15:32:32 2000  -0.910248 seconds
-
-For setting::
-
-	# /sbin/hwclock --systohc
-
-Root privileges are required to be able to set the time of day.
-
-4. Wakeup Alarm service
-=======================
-
-EFI provides an API by which one can program when a machine should wakeup,
-i.e. reboot. This is very different from the alarm provided by the legacy
-RTC which is some kind of interval timer alarm. For this reason we don't use
-the same ioctl()s to get access to the service. Instead we have
-introduced 2 news ioctl()s to the interface of an RTC.
-
-We have added 2 new ioctl()s that are specific to the EFI driver:
-
-	Read the current state of the alarm::
-
-		ioctl(d, RTC_WKALM_RD, &wkt)
-
-	Set the alarm or change its status::
-
-		ioctl(d, RTC_WKALM_SET, &wkt)
-
-The wkt structure encapsulates a struct rtc_time + 2 extra fields to get
-status information::
-
-  struct rtc_wkalrm {
-
-          unsigned char enabled; /* =1 if alarm is enabled */
-          unsigned char pending; /* =1 if alarm is pending  */
-
-          struct rtc_time time;
-  }
-
-As of today, none of the existing user-level apps supports this feature.
-However writing such a program should be hard by simply using those two
-ioctl().
-
-Root privileges are required to be able to set the alarm.

-IA-64 Specifics
-===============
-
- - General issues:
-
-    * Hardly any performance tuning has been done. Obvious targets
-      include the library routines (IP checksum, etc.). Less
-      obvious targets include making sure we don't flush the TLB
-      needlessly, etc.
-
-    * SMP locks cleanup/optimization
-
-    * IA32 support.  Currently experimental.  It mostly works.

-IRQ affinity on IA64 platforms
-==============================
-
-07.01.2002, Erich Focht <efocht@ess.nec.de>
-
-
-By writing to /proc/irq/IRQ#/smp_affinity the interrupt routing can be
-controlled. The behavior on IA64 platforms is slightly different from
-that described in Documentation/core-api/irq/irq-affinity.rst for i386 systems.
-
-Because of the usage of SAPIC mode and physical destination mode the
-IRQ target is one particular CPU and cannot be a mask of several
-CPUs. Only the first non-zero bit is taken into account.
-
-
-Usage examples
-==============
-
-The target CPU has to be specified as a hexadecimal CPU mask. The
-first non-zero bit is the selected CPU. This format has been kept for
-compatibility reasons with i386.
-
-Set the delivery mode of interrupt 41 to fixed and route the
-interrupts to CPU #3 (logical CPU number) (2^3=0x08)::
-
-     echo "8" >/proc/irq/41/smp_affinity
-
-Set the default route for IRQ number 41 to CPU 6 in lowest priority
-delivery mode (redirectable)::
-
-     echo "r 40" >/proc/irq/41/smp_affinity
-
-The output of the command::
-
-     cat /proc/irq/IRQ#/smp_affinity
-
-gives the target CPU mask for the specified interrupt vector. If the CPU
-mask is preceded by the character "r", the interrupt is redirectable
-(i.e. lowest priority mode routing is used), otherwise its route is
-fixed.
-
-
-
-Initialization and default behavior
-===================================
-
-If the platform features IRQ redirection (info provided by SAL) all
-IO-SAPIC interrupts are initialized with CPU#0 as their default target
-and the routing is the so called "lowest priority mode" (actually
-fixed SAPIC mode with hint). The XTP chipset registers are used as hints
-for the IRQ routing. Currently in Linux XTP registers can have three
-values:
-
-	- minimal for an idle task,
-	- normal if any other task runs,
-	- maximal if the CPU is going to be switched off.
-
-The IRQ is routed to the CPU with lowest XTP register value, the
-search begins at the default CPU. Therefore most of the interrupts
-will be handled by CPU #0.
-
-If the platform doesn't feature interrupt redirection IOSAPIC fixed
-routing is used. The target CPUs are distributed in a round robin
-manner. IRQs will be routed only to the selected target CPUs. Check
-with::
-
-        cat /proc/interrupts
-
-
-
-Comments
-========
-
-On large (multi-node) systems it is recommended to route the IRQs to
-the node to which the corresponding device is connected.
-For systems like the NEC AzusA we get IRQ node-affinity for free. This
-is because usually the chipsets on each node redirect the interrupts
-only to their own CPUs (as they cannot see the XTP registers on the
-other nodes).

-An ad-hoc collection of notes on IA64 MCA and INIT processing
-=============================================================
-
-Feel free to update it with notes about any area that is not clear.
-
----
-
-MCA/INIT are completely asynchronous.  They can occur at any time, when
-the OS is in any state.  Including when one of the cpus is already
-holding a spinlock.  Trying to get any lock from MCA/INIT state is
-asking for deadlock.  Also the state of structures that are protected
-by locks is indeterminate, including linked lists.
-
----
-
-The complicated ia64 MCA process.  All of this is mandated by Intel's
-specification for ia64 SAL, error recovery and unwind, it is not as
-if we have a choice here.
-
-* MCA occurs on one cpu, usually due to a double bit memory error.
-  This is the monarch cpu.
-
-* SAL sends an MCA rendezvous interrupt (which is a normal interrupt)
-  to all the other cpus, the slaves.
-
-* Slave cpus that receive the MCA interrupt call down into SAL, they
-  end up spinning disabled while the MCA is being serviced.
-
-* If any slave cpu was already spinning disabled when the MCA occurred
-  then it cannot service the MCA interrupt.  SAL waits ~20 seconds then
-  sends an unmaskable INIT event to the slave cpus that have not
-  already rendezvoused.
-
-* Because MCA/INIT can be delivered at any time, including when the cpu
-  is down in PAL in physical mode, the registers at the time of the
-  event are _completely_ undefined.  In particular the MCA/INIT
-  handlers cannot rely on the thread pointer, PAL physical mode can
-  (and does) modify TP.  It is allowed to do that as long as it resets
-  TP on return.  However MCA/INIT events expose us to these PAL
-  internal TP changes.  Hence curr_task().
-
-* If an MCA/INIT event occurs while the kernel was running (not user
-  space) and the kernel has called PAL then the MCA/INIT handler cannot
-  assume that the kernel stack is in a fit state to be used.  Mainly
-  because PAL may or may not maintain the stack pointer internally.
-  Because the MCA/INIT handlers cannot trust the kernel stack, they
-  have to use their own, per-cpu stacks.  The MCA/INIT stacks are
-  preformatted with just enough task state to let the relevant handlers
-  do their job.
-
-* Unlike most other architectures, the ia64 struct task is embedded in
-  the kernel stack[1].  So switching to a new kernel stack means that
-  we switch to a new task as well.  Because various bits of the kernel
-  assume that current points into the struct task, switching to a new
-  stack also means a new value for current.
-
-* Once all slaves have rendezvoused and are spinning disabled, the
-  monarch is entered.  The monarch now tries to diagnose the problem
-  and decide if it can recover or not.
-
-* Part of the monarch's job is to look at the state of all the other
-  tasks.  The only way to do that on ia64 is to call the unwinder,
-  as mandated by Intel.
-
-* The starting point for the unwind depends on whether a task is
-  running or not.  That is, whether it is on a cpu or is blocked.  The
-  monarch has to determine whether or not a task is on a cpu before it
-  knows how to start unwinding it.  The tasks that received an MCA or
-  INIT event are no longer running, they have been converted to blocked
-  tasks.  But (and its a big but), the cpus that received the MCA
-  rendezvous interrupt are still running on their normal kernel stacks!
-
-* To distinguish between these two cases, the monarch must know which
-  tasks are on a cpu and which are not.  Hence each slave cpu that
-  switches to an MCA/INIT stack, registers its new stack using
-  set_curr_task(), so the monarch can tell that the _original_ task is
-  no longer running on that cpu.  That gives us a decent chance of
-  getting a valid backtrace of the _original_ task.
-
-* MCA/INIT can be nested, to a depth of 2 on any cpu.  In the case of a
-  nested error, we want diagnostics on the MCA/INIT handler that
-  failed, not on the task that was originally running.  Again this
-  requires set_curr_task() so the MCA/INIT handlers can register their
-  own stack as running on that cpu.  Then a recursive error gets a
-  trace of the failing handler's "task".
-
-[1]
-    My (Keith Owens) original design called for ia64 to separate its
-    struct task and the kernel stacks.  Then the MCA/INIT data would be
-    chained stacks like i386 interrupt stacks.  But that required
-    radical surgery on the rest of ia64, plus extra hard wired TLB
-    entries with its associated performance degradation.  David
-    Mosberger vetoed that approach.  Which meant that separate kernel
-    stacks meant separate "tasks" for the MCA/INIT handlers.
-
----
-
-INIT is less complicated than MCA.  Pressing the nmi button or using
-the equivalent command on the management console sends INIT to all
-cpus.  SAL picks one of the cpus as the monarch and the rest are
-slaves.  All the OS INIT handlers are entered at approximately the same
-time.  The OS monarch prints the state of all tasks and returns, after
-which the slaves return and the system resumes.
-
-At least that is what is supposed to happen.  Alas there are broken
-versions of SAL out there.  Some drive all the cpus as monarchs.  Some
-drive them all as slaves.  Some drive one cpu as monarch, wait for that
-cpu to return from the OS then drive the rest as slaves.  Some versions
-of SAL cannot even cope with returning from the OS, they spin inside
-SAL on resume.  The OS INIT code has workarounds for some of these
-broken SAL symptoms, but some simply cannot be fixed from the OS side.
-
----
-
-The scheduler hooks used by ia64 (curr_task, set_curr_task) are layer
-violations.  Unfortunately MCA/INIT start off as massive layer
-violations (can occur at _any_ time) and they build from there.
-
-At least ia64 makes an attempt at recovering from hardware errors, but
-it is a difficult problem because of the asynchronous nature of these
-errors.  When processing an unmaskable interrupt we sometimes need
-special code to cope with our inability to take any locks.
-
----
-
-How is ia64 MCA/INIT different from x86 NMI?
-
-* x86 NMI typically gets delivered to one cpu.  MCA/INIT gets sent to
-  all cpus.
-
-* x86 NMI cannot be nested.  MCA/INIT can be nested, to a depth of 2
-  per cpu.
-
-* x86 has a separate struct task which points to one of multiple kernel
-  stacks.  ia64 has the struct task embedded in the single kernel
-  stack, so switching stack means switching task.
-
-* x86 does not call the BIOS so the NMI handler does not have to worry
-  about any registers having changed.  MCA/INIT can occur while the cpu
-  is in PAL in physical mode, with undefined registers and an undefined
-  kernel stack.
-
-* i386 backtrace is not very sensitive to whether a process is running
-  or not.  ia64 unwind is very, very sensitive to whether a process is
-  running or not.
-
----
-
-What happens when MCA/INIT is delivered what a cpu is running user
-space code?
-
-The user mode registers are stored in the RSE area of the MCA/INIT on
-entry to the OS and are restored from there on return to SAL, so user
-mode registers are preserved across a recoverable MCA/INIT.  Since the
-OS has no idea what unwind data is available for the user space stack,
-MCA/INIT never tries to backtrace user space.  Which means that the OS
-does not bother making the user space process look like a blocked task,
-i.e. the OS does not copy pt_regs and switch_stack to the user space
-stack.  Also the OS has no idea how big the user space RSE and memory
-stacks are, which makes it too risky to copy the saved state to a user
-mode stack.
-
----
-
-How do we get a backtrace on the tasks that were running when MCA/INIT
-was delivered?
-
-mca.c:::ia64_mca_modify_original_stack().  That identifies and
-verifies the original kernel stack, copies the dirty registers from
-the MCA/INIT stack's RSE to the original stack's RSE, copies the
-skeleton struct pt_regs and switch_stack to the original stack, fills
-in the skeleton structures from the PAL minstate area and updates the
-original stack's thread.ksp.  That makes the original stack look
-exactly like any other blocked task, i.e. it now appears to be
-sleeping.  To get a backtrace, just start with thread.ksp for the
-original task and unwind like any other sleeping task.
-
----
-
-How do we identify the tasks that were running when MCA/INIT was
-delivered?
-
-If the previous task has been verified and converted to a blocked
-state, then sos->prev_task on the MCA/INIT stack is updated to point to
-the previous task.  You can look at that field in dumps or debuggers.
-To help distinguish between the handler and the original tasks,
-handlers have _TIF_MCA_INIT set in thread_info.flags.
-
-The sos data is always in the MCA/INIT handler stack, at offset
-MCA_SOS_OFFSET.  You can get that value from mca_asm.h or calculate it
-as KERNEL_STACK_SIZE - sizeof(struct pt_regs) - sizeof(struct
-ia64_sal_os_state), with 16 byte alignment for all structures.
-
-Also the comm field of the MCA/INIT task is modified to include the pid
-of the original task, for humans to use.  For example, a comm field of
-'MCA 12159' means that pid 12159 was running when the MCA was
-delivered.

-Serial Devices
-==============
-
-Serial Device Naming
-====================
-
-    As of 2.6.10, serial devices on ia64 are named based on the
-    order of ACPI and PCI enumeration.  The first device in the
-    ACPI namespace (if any) becomes /dev/ttyS0, the second becomes
-    /dev/ttyS1, etc., and PCI devices are named sequentially
-    starting after the ACPI devices.
-
-    Prior to 2.6.10, there were confusing exceptions to this:
-
-	- Firmware on some machines (mostly from HP) provides an HCDP
-	  table[1] that tells the kernel about devices that can be used
-	  as a serial console.  If the user specified "console=ttyS0"
-	  or the EFI ConOut path contained only UART devices, the
-	  kernel registered the device described by the HCDP as
-	  /dev/ttyS0.
-
-	- If there was no HCDP, we assumed there were UARTs at the
-	  legacy COM port addresses (I/O ports 0x3f8 and 0x2f8), so
-	  the kernel registered those as /dev/ttyS0 and /dev/ttyS1.
-
-    Any additional ACPI or PCI devices were registered sequentially
-    after /dev/ttyS0 as they were discovered.
-
-    With an HCDP, device names changed depending on EFI configuration
-    and "console=" arguments.  Without an HCDP, device names didn't
-    change, but we registered devices that might not really exist.
-
-    For example, an HP rx1600 with a single built-in serial port
-    (described in the ACPI namespace) plus an MP[2] (a PCI device) has
-    these ports:
-
-      ==========  ==========     ============    ============   =======
-      Type        MMIO           pre-2.6.10      pre-2.6.10     2.6.10+

-      ==========  ==========     ============    ============   =======
-      builtin     0xff5e0000        ttyS0           ttyS1         ttyS0

-      MP 3        0xf8030038        ttyS4           ttyS4         ttyS4

-Console Selection
-=================
-
-    EFI knows what your console devices are, but it doesn't tell the
-    kernel quite enough to actually locate them.  The DIG64 HCDP
-    table[1] does tell the kernel where potential serial console
-    devices are, but not all firmware supplies it.  Also, EFI supports
-    multiple simultaneous consoles and doesn't tell the kernel which
-    should be the "primary" one.
-
-    So how do you tell Linux which console device to use?
-
-	- If your firmware supplies the HCDP, it is simplest to
-	  configure EFI with a single device (either a UART or a VGA
-	  card) as the console.  Then you don't need to tell Linux
-	  anything; the kernel will automatically use the EFI console.
-
-	  (This works only in 2.6.6 or later; prior to that you had
-	  to specify "console=ttyS0" to get a serial console.)
-
-	- Without an HCDP, Linux defaults to a VGA console unless you
-	  specify a "console=" argument.
-
-    NOTE: Don't assume that a serial console device will be /dev/ttyS0.
-    It might be ttyS1, ttyS2, etc.  Make sure you have the appropriate
-    entries in /etc/inittab (for getty) and /etc/securetty (to allow
-    root login).
-
-Early Serial Console
-====================
-
-    The kernel can't start using a serial console until it knows where
-    the device lives.  Normally this happens when the driver enumerates
-    all the serial devices, which can happen a minute or more after the
-    kernel starts booting.
-
-    2.6.10 and later kernels have an "early uart" driver that works
-    very early in the boot process.  The kernel will automatically use
-    this if the user supplies an argument like "console=uart,io,0x3f8",
-    or if the EFI console path contains only a UART device and the
-    firmware supplies an HCDP.
-
-Troubleshooting Serial Console Problems
-=======================================
-
-    No kernel output after elilo prints "Uncompressing Linux... done":
-
-	- You specified "console=ttyS0" but Linux changed the device
-	  to which ttyS0 refers.  Configure exactly one EFI console
-	  device[3] and remove the "console=" option.
-
-	- The EFI console path contains both a VGA device and a UART.
-	  EFI and elilo use both, but Linux defaults to VGA.  Remove
-	  the VGA device from the EFI console path[3].
-
-	- Multiple UARTs selected as EFI console devices.  EFI and
-	  elilo use all selected devices, but Linux uses only one.
-	  Make sure only one UART is selected in the EFI console
-	  path[3].
-
-	- You're connected to an HP MP port[2] but have a non-MP UART
-	  selected as EFI console device.  EFI uses the MP as a
-	  console device even when it isn't explicitly selected.
-	  Either move the console cable to the non-MP UART, or change
-	  the EFI console path[3] to the MP UART.
-
-    Long pause (60+ seconds) between "Uncompressing Linux... done" and
-    start of kernel output:
-
-	- No early console because you used "console=ttyS<n>".  Remove
-	  the "console=" option if your firmware supplies an HCDP.
-
-	- If you don't have an HCDP, the kernel doesn't know where
-	  your console lives until the driver discovers serial
-	  devices.  Use "console=uart,io,0x3f8" (or appropriate
-	  address for your machine).
-
-    Kernel and init script output works fine, but no "login:" prompt:
-
-	- Add getty entry to /etc/inittab for console tty.  Look for
-	  the "Adding console on ttyS<n>" message that tells you which
-	  device is the console.
-
-    "login:" prompt, but can't login as root:
-
-	- Add entry to /etc/securetty for console tty.
-
-    No ACPI serial devices found in 2.6.17 or later:
-
-	- Turn on CONFIG_PNP and CONFIG_PNPACPI.  Prior to 2.6.17, ACPI
-	  serial devices were discovered by 8250_acpi.  In 2.6.17,
-	  8250_acpi was replaced by the combination of 8250_pnp and
-	  CONFIG_PNPACPI.
-
-
-
-[1]
-    http://www.dig64.org/specifications/agreement
-    The table was originally defined as the "HCDP" for "Headless
-    Console/Debug Port."  The current version is the "PCDP" for
-    "Primary Console and Debug Port Devices."
-
-[2]
-    The HP MP (management processor) is a PCI device that provides
-    several UARTs.  One of the UARTs is often used as a console; the
-    EFI Boot Manager identifies it as "Acpi(HWP0002,700)/Pci(...)/Uart".
-    The external connection is usually a 25-pin connector, and a
-    special dongle converts that to three 9-pin connectors, one of
-    which is labelled "Console."
-
-[3]
-    EFI console devices are configured using the EFI Boot Manager
-    "Boot option maintenance" menu.  You may have to interrupt the
-    boot sequence to use this menu, and you will have to reset the
-    box after changing console configuration.

- * OpRegion handler to allow AML to call native firmware
- *
- * (c) Copyright 2007 Hewlett-Packard Development Company, L.P.
- *	Bjorn Helgaas <bjorn.helgaas@hp.com>
- *
- * This driver implements HP Open Source Review Board proposal 1842,
- * which was approved on 9/20/2006.
- *
- * For technical documentation, see the HP SPPA Firmware EAS, Appendix F.
- *
- * ACPI does not define a mechanism for AML methods to call native firmware
- * interfaces such as PAL or SAL.  This OpRegion handler adds such a mechanism.
- * After the handler is installed, an AML method can call native firmware by
- * storing the arguments and firmware entry point to specific offsets in the
- * OpRegion.  When AML reads the "return value" offset from the OpRegion, this
- * handler loads up the arguments, makes the firmware call, and returns the
- * result.
