In order to maintain the channel information per protocol, we need some sort of list or hashtable to hold all this information. IDR provides sparse array mapping of small integer ID numbers onto arbitrary pointers. In this case the arbitrary pointers can be pointers to the channel information. This patch adds support for per-protocol channels using those idr objects.

In order to support per-protocol channels if available, we need to factor out all the mailbox channel information(Tx/Rx payload and channel handle) out of the main SCMI instance information structure. This patch refactors the existing channel information into a separate chan_info structure.

In order to implement fast CPU DVFS switching, we need to perform all DVFS operations atomically. Since SCMI transfer already provide option to choose between pooling vs interrupt driven(default), we can opt for polling based transfers for set,get performance domain operations. This patch adds option to choose between polling vs interrupt driven SCMI transfers for set,get performance level operations.

It would be useful to have options to perform some SCMI transfers atomically by polling for the completion flag instead of interrupt driven. The SCMI specification has option to disable the interrupt and poll for the completion flag in the shared memory. This patch adds support for polling based SCMI transfers using that option. This might be used for uninterrupted/atomic DVFS operations from the scheduler context.

The sensor protocol provides functions to manage platform sensors, and provides the commands to describe the protocol version and the various attribute flags. It also provides commands to discover various sensors implemented and managed by the platform, read any sensor synchronously or asynchronously as allowed by the platform, program sensor attributes and/or configurations, if applicable. This patch adds support for most of the above features. Cc: Arnd Bergmann <arnd@arndb.de> Cc: Greg Kroah-Hartman <gregkh@linuxfoundation.org> Signed-off-by: Sudeep Holla <sudeep.holla@arm.com>

The clock protocol is intended for management of clocks. It is used to enable or disable clocks, and to set and get the clock rates. This protocol provides commands to describe the protocol version, discover various implementation specific attributes, describe a clock, enable and disable a clock and get/set the rate of the clock synchronously or asynchronously. This patch adds initial support for the clock protocol. Cc: Arnd Bergmann <arnd@arndb.de> Cc: Greg Kroah-Hartman <gregkh@linuxfoundation.org> Signed-off-by: Sudeep Holla <sudeep.holla@arm.com>

The performance protocol is intended for the performance management of group(s) of device(s) that run in the same performance domain. It includes even the CPUs. A performance domain is defined by a set of devices that always have to run at the same performance level. For example, a set of CPUs that share a voltage domain, and have a common frequency control, is said to be in the same performance domain. The commands in this protocol provide functionality to describe the protocol version, describe various attribute flags, set and get the performance level of a domain. It also supports discovery of the list of performance levels supported by a performance domain, and the properties of each performance level. This patch adds basic support for the performance protocol. Cc: Arnd Bergmann <arnd@arndb.de> Cc: Greg Kroah-Hartman <gregkh@linuxfoundation.org> Signed-off-by: Sudeep Holla <sudeep.holla@arm.com>

The SCMI specification encompasses various protocols. However, not every protocol has to be present on a given platform/implementation as not every protocol is relevant for it. Furthermore, the platform chooses which protocols it exposes to a given agent. The only protocol that must be implemented is the base protocol. The base protocol is used by an agent to discover which protocols are available to it. In order to enumerate the discovered implemented protocols, this patch adds support for a separate scmi protocol bus. It also adds mechanism to register support for different protocols.

The base protocol describes the properties of the implementation and provide generic error management. The base protocol provides commands to describe protocol version, discover implementation specific attributes and vendor/sub-vendor identification, list of protocols implemented and the various agents are in the system including OSPM and the platform. It also supports registering for notifications of platform errors. This protocol is mandatory. This patch adds support for the same along with some basic infrastructure to add support for other protocols.

The SCMI is intended to allow OSPM to manage various functions that are provided by the hardware platform it is running on, including power and performance functions. SCMI provides two levels of abstraction, protocols and transports. Protocols define individual groups of system control and management messages. A protocol specification describes the messages that it supports. Transports describe the method by which protocol messages are communicated between agents and the platform. This patch adds basic infrastructure to manage the message allocation, initialisation, packing/unpacking and shared memory management.

This patch adds devicetree binding for System Control and Management Interface (SCMI) Message Protocol used between the Application Cores(AP) and the System Control Processor(SCP). The MHU peripheral provides a mechanism for inter-processor communication between SCP's M3 processor and AP. SCP offers control and management of the core/cluster power states, various power domain DVFS including the core/cluster, certain system clocks configuration, thermal sensors and many others. SCMI protocol is developed as better replacement to the existing SCPI which is not flexible and easily extensible.

except, again, POLLFREE and POLL_BUSY_LOOP. With this, we finally get to the promised end result: - POLL{IN,OUT,...} are plain integers and *not* in __poll_t, so any stray instances of ->poll() still using those will be caught by sparse. - eventpoll.c and select.c warning-free wrt __poll_t - no more kernel-side definitions of POLL... - userland ones are visible through the entire kernel (and used pretty much only for mangle/demangle) - same behavior as after the first series (i.e. sparc et.al. epoll(2) working correctly).

This is the mindless scripted replacement of kernel use of POLL* variables as described by Al, done by this script: for V in IN OUT PRI ERR RDNORM RDBAND WRNORM WRBAND HUP RDHUP NVAL MSG; do L=`git grep -l -w POLL$V | grep -v '^t' | grep -v /um/ | grep -v '^sa' | grep -v '/poll.h$'|grep -v '^D'` for f in $L; do sed -i "-es/^\([^\"]*\)\(\<POLL$V\>\)/\\1E\\2/" $f; done done with de-mangling cleanups yet to come. NOTE! On almost all architectures, the EPOLL* constants have the same values as the POLL* constants do. But they keyword here is "almost". For various bad reasons they aren't the same, and epoll() doesn't actually work quite correctly in some cases due to this on Sparc et al. The next patch from Al will sort out the final differences, and we should be all done. Scripted-by: Al Viro <viro@zeniv.linux.org.uk> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

Pull more poll annotation updates from Al Viro: "This is preparation to solving the problems you've mentioned in the original poll series. After this series, the kernel is ready for running for V in IN OUT PRI ERR RDNORM RDBAND WRNORM WRBAND HUP RDHUP NVAL MSG; do L=`git grep -l -w POLL$V | grep -v '^t' | grep -v /um/ | grep -v '^sa' | grep -v '/poll.h$'|grep -v '^D'` for f in $L; do sed -i "-es/^\([^\"]*\)\(\<POLL$V\>\)/\\1E\\2/" $f; done done as a for bulk search-and-replace. After that, the kernel is ready to apply the patch to unify {de,}mangle_poll(), and then get rid of kernel-side POLL... uses entirely, and we should be all done with that stuff. Basically, that's what you suggested wrt KPOLL..., except that we can use EPOLL... instead - they already are arch-independent (and equal to what is currently kernel-side POLL...). After the preparations (in this series) switch to returning EPOLL... from ->poll() instances is completely mechanical and kernel-side POLL... can go away. The last step (killing kernel-side POLL... and unifying {de,}mangle_poll() has to be done after the search-and-replace job, since we need userland-side POLL... for unified {de,}mangle_poll(), thus the cherry-pick at the last step. After that we will have: - POLL{IN,OUT,...} *not* in __poll_t, so any stray instances of ->poll() still using those will be caught by sparse. - eventpoll.c and select.c warning-free wrt __poll_t - no more kernel-side definitions of POLL... - userland ones are visible through the entire kernel (and used pretty much only for mangle/demangle) - same behavior as after the first series (i.e. sparc et.al. epoll(2) working correctly)" * 'work.poll2' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs: annotate ep_scan_ready_list() ep_send_events_proc(): return result via esed->res preparation to switching ->poll() to returning EPOLL... add EPOLLNVAL, annotate EPOLL... and event_poll->event use linux/poll.h instead of asm/poll.h xen: fix poll misannotation smc: missing poll annotations
