2013-08-30drm/radeon: remove special handling for the DMA ringChristian König
Now that we have callbacks for [rw]ptr handling we can remove the special handling for the DMA rings and use the callbacks instead. Signed-off-by: Christian König <christian.koenig@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
2013-08-30drm/radeon: rework UVD writeback & [rw]ptr handlingChristian König
The hardware just doesn't support this correctly. Disable it before we accidentally write anywhere we shouldn't. Signed-off-by: Christian König <christian.koenig@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
2013-08-30drm/radeon: rework ring function handlingChristian König
Give the ring functions a separate structure and let the asic structure point to the ring specific functions. This simplifies the code and allows us to make changes at only one point. No change in functionality. Signed-off-by: Christian König <christian.koenig@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
2013-08-30drm/radeon: fix endian bugs in hw i2c atom routinesAlex Deucher
Need to swap the data fetched over i2c properly. This is the same fix as the endian fix for aux channel transactions. Signed-off-by: Alex Deucher <alexander.deucher@amd.com> Cc: stable@vger.kernel.org
2013-08-30drm/radeon/dpm: adjust the vblank time checks for eg, ni, siAlex Deucher
According to the internal teams, we never hit the limit for mclk switching on these asics, so we can disable the check. Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
2013-08-30drm/radeon/dpm: add reclocking quirk for ASUS K70AFAlex Deucher
The LCD has a relatively short vblank time (216us), but the card is able to reclock memory fine in that time. Signed-off-by: Alex Deucher <alexander.deucher@amd.com> Reported-by: normalrawr@gmail.com
2013-08-30drm/radeon/dpm: implement UVD powergating for CIAlex Deucher
Disable the UVD block when not in use to save power. The block is not actually powergated on CI, but we switch between UVD DPM (where the uvd clocks are adjusted on demand) and clocks off. Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
2013-08-30drm/radeon/dpm: implement UVD powergating for KB/KVAlex Deucher
Powergate the UVD block when not in use to save power. Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
2013-08-30drm/radeon: restructure UVD code to handle UVD PG (v2)Alex Deucher
When we PG (powergate) UVD, we need to re-initialize it before we can use it again. v2: rebase on UVD stop fixes Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
2013-08-30drm/radeon/dpm: add new callback for powergating UVD (v4)Alex Deucher
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 selection rework v4: fix inverted logic typo noticed by Christian Signed-off-by: Alex Deucher <alexander.deucher@amd.com>

2013-08-30drm/radeon/dpm: implement vblank_too_short callback for CIAlex Deucher
