Subject: [PATCH v14 0/6] Invoke rpmh_flush for non OSI targets
Date: Thu, 26 Mar 2020 23:07:44 +0530 [thread overview]
Message-ID: <1585244270-637-1-git-send-email-mkshah@codeaurora.org> (raw)
Changes in v14:
- Address Doug's comments on change 3 from v13
- Drop new APIs for start and end transaction from change 4 in v13
- Update change 4 to use cpu pm notifications instead
- Add [5] as change 5 to enable use of WAKE TCS when ACTIVE TCS count is 0
- Add change 6 to Allow multiple WAKE TCS to be used as ACTIVE TCSes
- First 4 changes can be merged even without change 5 and 6.
Changes in v13:
- Address Stephen's comment to maintain COMPILE_TEST
- Address Doug's comments and add new APIs for start and end transaction
Changes in v12:
- Kconfig change to remove COMPILE_TEST was dropped in v11, reinclude it.
Changes in v11:
- Address Doug's comments on change 2 and 3
- Include change to invalidate TCSes before flush from [4]
Changes in v10:
- Address Evan's comments to update commit message on change 2
- Add Evan's Reviewed by on change 2
- Remove comment from rpmh_flush() related to last CPU invoking it
- Rebase all changes on top of next-20200302
Changes in v9:
- Keep rpmh_flush() to invoke from within cache_lock
- Remove comments related to only last cpu invoking rpmh_flush()
Changes in v8:
- Address Stephen's comments on changes 2 and 3
- Add Reviewed by from Stephen on change 1
Changes in v7:
- Address Srinivas's comments to update commit text
- Add Reviewed by from Srinivas
Changes in v6:
- Drop 1 & 2 changes from v5 as they already landed in maintainer tree
- Drop 3 & 4 changes from v5 as no user at present for power domain in rsc
- Rename subject to appropriate since power domain changes are dropped
- Rebase other changes on top of next-20200221
Changes in v5:
- Add Rob's Acked by on dt-bindings change
- Drop firmware psci change
- Update cpuidle stats in dtsi to follow PC mode
- Include change to update dirty flag when data is updated from [4]
- Add change to invoke rpmh_flush when caches are dirty
Changes in v4:
- Add change to allow hierarchical topology in PC mode
- Drop hierarchical domain idle states converter from v3
- Address Merge sc7180 dtsi change to add low power modes
Changes in v3:
- Address Rob's comment on dt property value
- Address Stephen's comments on rpmh-rsc driver change
- Include sc7180 cpuidle low power mode changes from [1]
- Include hierarchical domain idle states converter change from [2]
Changes in v2:
- Add Stephen's Reviewed-By to the first three patches
- Addressed Stephen's comments on fourth patch
- Include changes to connect rpmh domain to cpuidle and genpds
Resource State Coordinator (RSC) is responsible for powering off/lowering
the requirements from CPU subsystem for the associated hardware like buses,
clocks, and regulators when all CPUs and cluster is powered down.
RSC power domain uses last-man activities provided by genpd framework based
on Ulf Hansoon's patch series[3], when the cluster of CPUs enter deepest
idle states. As a part of domain poweroff, RSC can lower resource state
requirements by flushing the cached sleep and wake state votes for various
resources.
