Hello all,
The purpose of this email is to get other opinions and advices to buffer
synchronization mechanism, and coupling cache operation feature with the buffer
synchronization mechanism. First of all, I am not a native English speaker so
I'm not sure that I can convey my intention to you.

This fixes a deadlock inversion when vblank is enabled/disabled by drm.
dev-vblank_time_lock is always taken when the vblank state is toggled,
which caused a deadlock when event-lock was also taken during
event_get/put.
Solve the race by requiring that lock to change enable/disable state,
and
Not as thoroughly tested as I would like. Newer nvd0 and kepler are unsupported,
as I don't know the registers yet.
Information of the scanout position is based on Lucas Stach's original patch,
with a teak to read vline twice, to prevent a race of hline with vline.

This is the initial set of patches for 3.12 for radeon. The
big changes here are adding ASPM and DPM support to CIK asics.
There are also some cleanups related to removing bo copy support
using the 3D engine in favor of the sDMA engines or CP DMA.
For easier review the patches are also available
CP DMA is lighter weight than using the 3D engine.

Add a helper function for counting the number of open stream handles.
v2: fix copy-pasta in comments and whitespace error
v3: make function static since it's only used in radeon_uvd.c
at the moment
v4: make non-static again for future changes
v5: make static again for new rework of dpm uvd
Use the UVD handle information to determine which
which power states to select when using UVD. For
example, decoding a single SD stream requires much
lower clocks than multiple HD streams.
v2: switch to a cleaner dpm/uvd interface
v3: change the uvd power state while streams
are active if need
1. Handle the the thermal state directly in the work handler.
Remove the state selection function since nothing else uses it now.
2. On some asics there is no thermal state, so we just use a regular
state and force the low performance state.

Newer asics have a lot of vram so it's less of an
issue to waste a little more space for the gart
page table. This gives us some additional gart space
before having to migrate to non-gart system ram
for games, etc. where we use up most of vram.

Starting on CIK, multi-media blocks like UVD no longer
have special power state. Rather they have their own
DPM implementation which adjusts their clocks dynamically
when active. When they are not active, the blocks are
powergated to save power.
v2: add missing pm locks
v3: rebase on uvd state
When we PG (powergate) UVD, we need to re-initialize it
before we can use it again.

I believe there's areas in here where the SBIOS/VBIOS can communicate

Hello all,
The purpose of this email is to get other opinions and advices to buffer
synchronization mechanism, and coupling cache operation feature with the buffer
synchronization mechanism. First of all, I am not a native English speaker so
I'm not sure that I can convey my intention to you.
Hi

Allocating type=0 marks the memory as free. This allows the ltcg memory to be
allocated twice. Add a BUG_ON in core/mm.c to prevent this ever happening again.

Some registers were not initialized in init, this causes them to be
uninitialized after suspend.

This fixes a deadlock inversion when vblank is enabled/disabled by drm.

Solve the race by requiring that lock to change enable/disable state,
and always
Not as thoroughly tested as I would like. Newer nvd0 and kepler are unsupported,
as I don't know the registers yet.
Information of the scanout position is based on Lucas Stach's original patch,
with a teak to read vline twice, to prevent a race of hline with vline.

This is the initial set of patches for 3.12 for radeon. The
big changes here are adding ASPM and DPM support to CIK asics.
There are also some cleanups related to removing bo copy support
using the 3D engine in favor of the sDMA engines or CP DMA.
For easier review the patches are also available
CP DMA is lighter weight than using the 3D engine.

No longer used now that we use the async dma engines or
CP DMA for bo copies.

Add a helper function for counting the number of open stream handles.
v2: fix copy-pasta in comments and whitespace error
v3: make function static since it's only used in radeon_uvd.c
at the moment
v4: make non-static again for future changes
v5: make static again for new rework of dpm uvd
Use the UVD handle information to determine which
which power states to select when using UVD. For
example, decoding a single SD stream requires much
lower clocks than multiple HD streams.
v2: switch to a cleaner dpm/uvd interface
v3: change the uvd power state while streams
are active if need
1. Handle the the thermal state directly in the work handler.
Remove the state selection function since nothing else uses it now.
2. On some asics there is no thermal state, so we just use a regular
state and force the low performance state.

Newer asics have a lot of vram so it's less of an
issue to waste a little more space for the gart
page table. This gives us some additional gart space
before having to migrate to non-gart system ram
for games, etc. where we use up most of vram.
