[PATCH 0/1] remove snb rc6 patches from v3.4 kernel repository

[nitin.a.kamble]

From: Nitin A Kamble <nitin.a.kamble@intel.com>

These patches are already part of v3.4 kernel sources. So there is no need to 
maintain them in the yocto linux 3.4 repository.

Thanks,
Nitin

[PATCH 1/1] rc6: remove rc6 patches for snb

[nitin.a.kamble]

From: Nitin A Kamble <nitin.a.kamble@intel.com>

The sandybridge rc6 patches are part of the released v3.4 kernel.
Hence there is no need to keep these patches in the 3.4 linux
yocto kernel repository.

-Subject: [PATCH] drm/i915: allow to select rc6 modes via kernel parameter
-
-This allows to select which rc6 modes are to be used via kernel parameter,
-via a bitmask parameter. E.g.:
-
-- to enable rc6, i915_enable_rc6=1
-- to enable rc6 and deep rc6, i915_enable_rc6=3
-- to enable rc6 and deepest rc6, use i915_enable_rc6=5
-- to enable rc6, deep and deepest rc6, use i915_enable_rc6=7
-
-Please keep in mind that the deepest RC6 state really should NOT be used
-by default, as it could potentially worsen the issues with deep RC6. So do
-enable it only when you know what you are doing. However, having it around
-could help solving possible future rc6-related issues and their debugging
-on user machines.
-
-Note that this changes behavior - previously, value of 1 would enable both
-RC6 and deep RC6. Now it should only enable RC6 and deep/deepest RC6
-stages must be enabled manually.
-
-v2: address Chris Wilson comments and clean up the code.

-Subject: [PATCH] drm/i915: do not enable RC6p on Sandy Bridge
-
-With base on latest findings, RC6p seems to be respondible for RC6-related
-issues on Sandy Bridge platform. To work-around those issues, the previous
-solution was to completely disable RC6 on Sandy Bridge for the past few
-releases, even if plain RC6 was not giving any issues.
-
-What this patch does is preventing RC6p from being enabled on Sandy Bridge
-even if users enable RC6 via a kernel parameter. So it won't change the
-defaults in any way, but will ensure that if users do enable RC6 manually
-it won't break their machines by enabling this extra state.
-
-Proper fix for this (enabling specific RC6 states according to the GPU
-generation) were proposed for the -next kernel, but we are too late in the
-release process now to pick such changes.

-Subject: [PATCH] drm/i915: enable plain RC6 on Sandy Bridge by default
-
-This is yet another chapter in the ongoing saga of bringing RC6 to Sandy
-Bridge machines by default.
-
-Now that we have discovered that RC6 issues are triggered by RC6+ state,
-let's try to disable it by default. Plain RC6 is the one responsible for
-most energy savings, and so far it haven't given any problems - at least,
-none we are aware of.
-
-So with this, when i915_enable_rc6=-1 (e.g., the default value), we'll
-attempt to enable plain RC6 only on SNB. For Ivy Bridge, the behavior
-stays the same as always - we enable both RC6 and deep RC6.
-
-Note that while this exact patch does not has explicit tested-by's, the
-equivalent settings were fixed in 3.3 kernel by a smaller patch. And it
-has also received considerable testing through Canonical RC6 task-force
-testing at https://wiki.ubuntu.com/Kernel/PowerManagementRC6. Up to date,
-it looks like all the known issues are gone.
-
-v2: improve description and reference a couple of open bugs related to
-RC6 which seem to be fixed with this change.

dropped. They obviously weren't reference anyway.

I assume you'll be doing an associated meta-intel commit to remove the
reference in:

./meta-sugarbay/recipes-kernel/linux/linux-yocto_3.2.bbappend

Bruce,
I think these rc6 patches are still needed for linux-yocto_3.2.bbappend. And they are referenced in the sugarbay bsp 3.2 Yocto kernel as you note above. The commit I sent is for for v3.4 yocto kernel tree. 
Are you saying about dropping rc6 patches from the 3.2 kernel tree as well?

Nitin

Yes, of course it's for 3.4 .. that's where I merged it :)

I was more reminding for any updates to the BSP to 3.4 .. i.e. don't

   I see your point now.  I have dropped them from 3.4 kernel recipe 1st to avoid patch application errors. Then we realized that these patches are not needed in the v3.4 kernel repository.
