I do have documentation (tim.mann@compaq.com) that partially covers these models,
but no units to experiment with. The MS-124W support is tested with a real unit.
The MS-124T support is untested, but should work.
The Generic driver supports multiple input and output substreams over a single
serial port. Similar to Roland Soundcanvas mode, F5 NN is used to select the
appropriate input or output stream (depending on the data direction).
Additionally, the CTS signal is used to regulate the data flow. The number of
inputs is specified by the snd_ins parameter.
Documentation/vm/hugetlbpage.txt 0 → 100644
View file @ ff61d1d6
2002 Rohit Seth <rohit.seth@intel.com>
The intent of this file is to give a brief summary of hugetlbpage support in
the Linux kernel. This support is built on top of multiple page size support
that is provided by most of modern architectures. For example, IA-32
architecture supports 4K and 4M (2M in PAE mode) page sizes, IA-64
architecture supports multiple page sizes 4K, 8K, 64K, 256K, 1M, 4M, 16M,
256M. A TLB is a cache of virtual-to-physical translations. Typically this
is a very scarce resource on processor. Operating systems try to make best
use of limited number of TLB resources. This optimization is more critical
now as bigger and bigger physical memories (several GBs) are more readily
available.
The current support is provided in kernel using the following two system calls:
1) sys_alloc_hugepages(int key, unsigned long addr, size_t len, int prot, int flag)
2) sys_free_hugepages(unsigned long addr)
Arguments to these system calls are defined as follows:
key: If a user application wants to share hugepages with other
processes then this input argument needs to be greater than 0.
Different applications can use the same key to map the same physical
memory (mapped by hugeTLBs) in their address space. When a process
forks, then children share the same physical memory with their parent.
For the cases when an application wishes to keep the huge pages
private, the key value of 0 is defined. In this case kernel allocates
hugetlb pages to the process that are not shareable across different
processes. These segments are marked private for the process. These
segments are not copied to children's address space on forks.
AKPM: So what is present at that address within the child?
The key manangement (and assignment) part is left to user
applications.
addr: This is an address hint. The kernel will perform a sanity check
on this address (alignment etc.) before using it. It is possible that
kernel will allocates a different address (on success).
len: Length of the required segment. Applications are expected to give
HPAGE_SIZE aligned length. (Else EINVAL is returned.)
prot: The prot parameter specifies the desired memory protection on the
requested hugepages. The possible values are PROT_EXEC, PROT_READ,
PROT_WRITE.
flag: This parameter can only take the value IPC_CREAT for the cases
when "key" value greater than zero (shared hugepage cases). It is
ignored for values of "key" that are <= 0.
This parameter indicates that the kernel should create a new huge
page segment (corresponding to "key"), if none already exists. If this
flag is not set, then sys_allochugepages() will return ENOENT if there
is no segment associated with corresponding "key".
In case of success, sys_alloc_hugepages() return the allocated virtual address.
sys_free_hugepages() frees the hugetlb resources from the calling process's
address space. The input argument "addr" specifies the segment that needs to
be freed. It is important to note that for the shared hugepage cases, the
underlying hugepages are freed onlyafter all the users of those pages have
either freed those hugepages or have exited.
/proc/sys/vm_nr_hugepages indicates the current number of configured hugetlb
pages in the kernel. Super user privileges are required for modification of
this value. The allocation of hugetlb pages is posible only if there are
enough physically contiguous free pages in system OR if there are enough
hugetlb pages free that can be transfered back to regular memory pool.
/proc/meminfo also gives the information about the total number of hugetlb
pages configured in the kernel. It also displays information about the
number of free hugetlb pages at any time. It also displays information about
the configured hugepage size - this is needed for generting the proper
alignment and size of the arguments to the above system calls.
Pages that are used as hugetlb pages are marked reserved inside the kernel.
This allows hugetlb pages to be always locked in memory. The user either
needs to be super user to use these pages or one of supplementary group
should include root. In future there will be support to check RLIMIT_MLOCK
for limited (number of hugetlb pages) usage to unprivileged applications.
If the kernel does not support hugepages these system calls will return ENOSYS.

CONFIG_ARCH_ARCA5K
This selects what ARM system you wish to build the kernel for. It
also selects to some extent the CPU type. If you are unsure what
to set this option to, please consult any information supplied with
your system.
CONFIG_ARCH_A5K
Say Y here to to support the Acorn A5000. Linux can support the
internal IDE disk and CD-ROM interface, serial and parallel port,
and the floppy drive. Note that on some A5000s the floppy is
plugged into the wrong socket on the motherboard.
CONFIG_ARCH_ARC
The Acorn Archimedes was an personal computer based on an 8K ARM2
processor, released in 1987. It supported 512K of RAM and 2 800K
floppy disks. Picture and more detailed specifications at
<http://www.computingmuseum.com/museum/archi.htm>.
CONFIG_PAGESIZE_16
Say Y here if your Archimedes or A5000 system has only 2MB of
memory, otherwise say N. The resulting kernel will not run on a
machine with 4MB of memory.

CONFIG_ARCH_AUTCPU12
Say Y if you intend to run the kernel on the autronix autcpu12
board. This board is based on a Cirrus Logic CS89712.
CONFIG_ARCH_CDB89712
This is an evaluation board from Cirrus for the CS89712 processor.
The board includes 2 serial ports, Ethernet, IRDA, and expansion
headers. It comes with 16 MB SDRAM and 8 MB flash ROM.
CONFIG_ARCH_CEIVA
Say Y here if you intend to run this kernel on the Ceiva/Polaroid
PhotoMax Digital Picture Frame.
CONFIG_ARCH_EDB7211
Say Y here if you intend to run this kernel on a Cirrus Logic EDB-7211
evaluation board.
CONFIG_ARCH_P720T
Say Y here if you intend to run this kernel on the ARM Prospector
720T.
CONFIG_EP72XX_ROM_BOOT
If you say Y here, your CLPS711x-based kernel will use the bootstrap
mode memory map instead of the normal memory map.
Processors derived from the Cirrus CLPS-711X core support two boot
modes. Normal mode boots from the external memory device at CS0.
Bootstrap mode rearranges parts of the memory map, placing an
internal 128 byte bootstrap ROM at CS0. This option performs the
address map changes required to support booting in this mode.
You almost surely want to say N here.

Enabling this feature will cause a message to be printed when the P4
enters thermal throttling.
CONFIG_CPU_FREQ
Clock scaling allows you to change the clock speed of CPUs on the
fly. This is a nice method to save battery power on notebooks,
because the lower the clock speed, the less power the CPU consumes.
For more information, take a look at linux/Documentation/cpufreq or
at <http://www.brodo.de/cpufreq/>
If in doubt, say N.
CONFIG_CPU_FREQ_24_API
This enables the /proc/sys/cpu/ sysctl interface for controlling
CPUFreq, as known from the 2.4.-kernel patches for CPUFreq. Note
that some drivers do not support this interface or offer less
functionality.
If you say N here, you'll be able to control CPUFreq using the
new /proc/cpufreq interface.
For details, take a look at linux/Documentation/cpufreq.
If in doubt, say N.
CONFIG_X86_POWERNOW_K6
This adds the CPUFreq driver for mobile AMD K6-2+ and mobile
AMD K6-3+ processors.
For details, take a look at linux/Documentation/cpufreq.
If in doubt, say N.
CONFIG_X86_P4_CLOCKMOD
This adds the CPUFreq driver for Intel Pentium 4 / XEON
processors.
For details, take a look at linux/Documentation/cpufreq.
If in doubt, say N.
CONFIG_ELAN_CPUFREQ
This adds the CPUFreq driver for AMD Elan SC400 and SC410
processors.
You need to specify the processor maximum speed as boot
parameter: elanfreq=maxspeed (in kHz) or as module
parameter "max_freq".
For details, take a look at linux/Documentation/cpufreq.
If in doubt, say N.
CONFIG_X86_LONGHAUL
This adds the CPUFreq driver for VIA Samuel/CyrixIII,
VIA Cyrix Samuel/C3, VIA Cyrix Ezra and VIA Cyrix Ezra-T
processors.
For details, take a look at linux/Documentation/cpufreq.
If in doubt, say N.
CONFIG_X86_SPEEDSTEP
This adds the CPUFreq driver for certain mobile Intel Pentium III
(Coppermine), all mobile Intel Pentium III-M (Tulatin) and all
mobile Intel Pentium 4 P4-Ms.
For details, take a look at linux/Documentation/cpufreq.
If in doubt, say N.
CONFIG_X86_LONGRUN
This adds the CPUFreq driver for Transmeta Crusoe processors which
support LongRun.
For details, take a look at linux/Documentation/cpufreq.
If in doubt, say N.
CONFIG_TOSHIBA
