2014-12-03drm/radeon: Re-show the cursor after a modesetMichel Dänzer1-0/+1
Setting a mode seems to clear the cursor registers, so we need to re-program them to make sure the cursor is visible. Signed-off-by: Michel Dänzer <michel.daenzer@amd.com> Reviewed-by: Alex Deucher <alexander.deucher@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
2014-04-01drm: Replace crtc fb with primary plane fb (v3)Matt Roper1-8/+8
Now that CRTC's have a primary plane, there's no need to track the framebuffer in the CRTC. Replace all references to the CRTC fb with the primary plane's fb. This patch was generated by the Coccinelle semantic patching tool using the following rules: @@ struct drm_crtc C; @@ - (C).fb + C.primary->fb @@ struct drm_crtc *C; @@ - (C)->fb + C->primary->fb v3: Generate patch via coccinelle. Actual removal of crtc->fb has been moved to a subsequent patch. v2: Fixup several lingering crtc->fb instances that were missed in the first patch iteration.

2013-11-15radeon: workaround pinning failure on low ram gpuJerome Glisse1-0/+28
GPU with low amount of ram can fails at pinning new framebuffer before unpinning old one. On such failure, retry with unpinning old one before pinning new one allowing to work around the issue.

2013-11-08drm/radeon/kms: add crtc_disable function for legacy crtcIlija Hadzic1-0/+21
To plug the VRAM memory leak (see previous patch for details) we must unpin the frame buffer when disabling the CRTC. This warrants the addition of disable function for legacy CRTC, which puts the CRTC in DPMS-OFF state and unpins the frame buffer if there is one associated with the CRTC.

2012-11-01DRM/radeon: For single CRTC GPUs move handling of CRTC_CRT_ON to crtc_dpms().Egbert Eich1-2/+13
On all dual CRTC GPUs the CRTC_CRT_ON in the RADEON_CRTC_EXT_CNTL register controls the CRTC of the primary DAC. Therefore it is set in the DAC DMPS function. This is different for GPU's with a single CRTC but a primary and a TV DAC: here it controls the single CRTC no matter where it is routed. Therefore we set it here. This avoids an elaborate on/off state tracking since both primary_dac_dpms() and tv_dac_dpms() functions would have to touch this bit. On single CRTC GPUs with just one DAC it's irrelevant where this bit is handled. agd5f: fix warning Signed-off-by: Egbert Eich <eich@suse.de> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>

2010-02-18drm/radeon/kms: simplify memory controller setup V2Jerome Glisse1-1/+1
Get rid of _location and use _start/_end also simplify the computation of vram_start|end & gtt_start|end. For R1XX-R2XX we place VRAM at the same address of PCI aperture, those GPU shouldn't have much memory and seems to behave better when setup that way. For R3XX and newer we place VRAM at 0. For R6XX-R7XX AGP we place VRAM before or after AGP aperture this might limit to limit the VRAM size but it's very unlikely. For IGP we don't change the VRAM placement. Tested on (compiz,quake3,suspend/resume): PCI/PCIE:RV280,R420,RV515,RV570,RV610,RV710 AGP:RV100,RV280,R420,RV350,RV620(RPB*),RV730 IGP:RS480(RPB*),RS690,RS780(RPB*),RS880 RPB: resume previously broken V2 correct commit message to reflect more accurately the bug and move VRAM placement to 0 for most of the GPU to avoid limiting VRAM.
