[PATCH v10 0/1] PCC: Platform Communication Channel

by Ashwin Chaugule

Changes since V9: - Default to PCC subspace headers as defined in ACPI v5.1 Changes since V8: - Removed unncessary header files. - Added kerneldoc comments. - Added intro about PCC in pcc.c Changes since V7: - Added timeout to tx method in case the remote dies. - Restructured usage of acpi_status. Had inverted logic previously. Changes since V6: - Cosmetic changes based on Lv's suggestions Changes since V5: - Optimize loop that matches channel request. - Use platform_create_bundle. - Replace ioread/writes. - Remove redundant code and headers. - Restructure common mailbox macros. - Reformat PCC cmd parsing. Changes since V4: - Folded PCC Mailbox helpers into pcc.c Changes since V3: - Added PCC helper functions to work around "struct device" limitations. - PCC driver changes to work with PCC specific Mailbox helpers. Changes since V2: - Rebased on top of git://git.linaro.org/landing-teams/working/fujitsu/integration.git branch mailbox-for-3.17 - Added PCC API to mailbox framework as per Arnd's suggestion to allow usage without ACPI. Changes since V1: - Integration with Mailbox framework - https://lkml.org/lkml/2014/5/15/49 This patchset adds support for the PCC (Platform Communication Channel) interface as described in the current ACPI 5.0 spec. See Section 14 of the ACPI spec - http://acpi.info/DOWNLOADS/ACPI_5_Errata%20A.pdf for more details on how PCC works. In brief PCC is a generic means for PCC clients, to talk to the firmware. The PCC register space is typically memory mapped IO and uses a doorbell mechanism to communicate synchronously from the OS to the firmware. The PCC driver is completely agnostic to the protocol implemented by the PCC clients. It only implements the enumeration of PCC channels and the low level transport mechanism and leaves the rest to the PCC clients. The PCC is meant to be useable in the future by clients such as CPPC (Collaborative Processor Performance Control), RAS (Reliability, Availability and Serviceability) and MPST (Memory Power State Tables) and possibly others.

A new fwts test result (using the latest leg kernel)

by Fu Wei

Hi our dear ACPI experts, I ran my ci job yesterday night. then I run a test on my new leg Image, because I recompiled the FWTS in the test , so the test took a long time. https://validation.linaro.org/scheduler/job/198839/log_file The result.log is attached. UPDATE: (1)disabling STATIC_DEVMEM is working, it's not a blocker for FWTS in short term. (2)we test the latest kernel, so the result should be better Please let me know what are the rest problem we need to fix , according to the test log. Great thanks for your time! -- Best regards, Fu Wei Software Engineer From Red Hat LEG Team Linaro.org | Open source software for ARM SoCs Ph: +86 186 2020 4684 (mobile) IRC: fuwei Skype: tekkamanninja Room 1512, Regus One Corporate Avenue,Level 15, One Corporate Avenue,222 Hubin Road,Huangpu District, Shanghai,China 200021

[PATCH] mailbox: enable non-DT/ACPI clients to use the api

by Jassi Brar

The Mailbox API so far discounted controllers and clients that may not have a DT based channel mapping capability, as in ACPI. Allow such mailbox clients to ask for a mailbox channel by simply specifying a token. The token would be globally unique among channels provided by such controllers... which shouldn't be a problem because practically non-DT means ACPI and ACPI specifies just one controller instance called the Platform Communications Channel (PCC) that could have max 256 subspaces (channels or mailboxes). So this is simply going to be the value from 'Signature' field (first 4bytes) of the SharedMemory Region corresponding to the subspace/channel the client is interested in.
