2020-01-04drm/gma500: fix memory disclosures due to uninitialized bytesKangjie Lu
[ Upstream commit ec3b7b6eb8c90b52f61adff11b6db7a8db34de19 ] "clock" may be copied to "best_clock". Initializing best_clock is not sufficient. The fix initializes clock as well to avoid memory disclosures and informaiton leaks.

2014-04-01drm: Replace crtc fb with primary plane fb (v3)Matt Roper
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.

2013-11-08drm/gma500/mrst: Replace WMs and chickenbits with values from EMGDPatrik Jakobsson
For the minnowboard to work the values found in EMGD are required. This might break Oaktrail but without hardware to test with I cannot really tell (and do not really care). Signed-off-by: Patrik Jakobsson <patrik.r.jakobsson@gmail.com>
2013-11-08drm/gma500/mrst: Properly route oaktrail hdmi hooksPatrik Jakobsson
Since we can have SDVO on Pipe B we better check the output type instead of pipe number for Oaktrail HDMI. Signed-off-by: Patrik Jakobsson <patrik.r.jakobsson@gmail.com>
2013-11-08drm/gma500/mrst: Add aux register writes when programming pipePatrik Jakobsson
On SDVO pipes (always Pipe B on mrst) we have to sequentially write the aux vdc. We might be able to skip programming the primary vdc in some/most places but we don't care about that now. Signed-off-by: Patrik Jakobsson <patrik.r.jakobsson@gmail.com>
2013-11-08drm/gma500/mrst: Add SDVO clock calculationPatrik Jakobsson
We start off by adding SDVO limits and converting all limits to the generic gma_limit_t stuct. Then we separate clock calculations for LVDS and SDVO. This will be cleaned up later but keep it simple for now. Signed-off-by: Patrik Jakobsson <patrik.r.jakobsson@gmail.com>

2013-07-24drm/gma500/oak: Use identical generic crtc funcsPatrik Jakobsson
Use the generic gma functions instead of the oaktrail functions where they are identical. Signed-off-by: Patrik Jakobsson <patrik.r.jakobsson@gmail.com>
2013-07-24drm/gma500: Convert to generic gamma funcsPatrik Jakobsson
This takes care of the remaining chips using the old generic code. We don't check if the pipe number is valid but the old code peeked in the register map before checking anyways so just ignore it. Signed-off-by: Patrik Jakobsson <patrik.r.jakobsson@gmail.com>
2013-07-24drm/gma500: Make all chips use gma_wait_for_vblankPatrik Jakobsson

2013-07-24drm/gma500: Make use of gma_pipe_has_type()Patrik Jakobsson
Replace any use of xxx_intel_pipe_has_type() with the generic gma_pipe_has_type() function. Poulsbo still use it but that will be removed when we rip out psb_intel_pipe_has_type(). Signed-off-by: Patrik Jakobsson <patrik.r.jakobsson@gmail.com>

2012-11-07gma600: Enable HDMI supportAlan Cox
There are still some mysteries left, in particular how (and in fact if) the EDID is supposed to work on the HDMI port. However the basic stuff now works and I can plug my Q550 into an HDMI display and get the expected results.

2011-12-20drm: Replace pitch with pitches[] in drm_framebufferVille Syrjälä
Otherwise each driver would need to keep the information inside their own framebuffer object structure. Also add offsets[]. BOs on the other hand are driver specific, so those can be kept in driver specific structures.
