2015-06-19drm/radeon: fix DRM_IOCTL_RADEON_CS oopsTommi Rantala
commit a28b2a47edcd0cb7c051b445f71a426000394606 upstream. Passing zeroed drm_radeon_cs struct to DRM_IOCTL_RADEON_CS produces the following oops.

This poisons the TLB with invalid entries which are sometimes not correctly removed on TLB flush. For stable inclusion the patch probably needs to be modified a bit.

2014-06-07drm/radeon: Another card with wrong primary dac adjOndrej Zary
commit f7929f34fa0e0bb6736a2484fdc07d77a1653081 upstream. Hello, got another card with "too bright" problem: Sapphire Radeon VE 7000 DDR (VGA+S-Video) lspci -vnn: 01:00.0 VGA compatible controller [0300]: Advanced Micro Devices [AMD] nee ATI RV100 QY [Radeon 7000/VE] [1002:5159] (prog-if 00 [VGA controller]) Subsystem: PC Partner Limited Sapphire Radeon VE 7000 DDR [174b:7c28] The patch below fixes the problem for this card. But I don't like the blacklist, couldn't some heuristic be used instead? The interesting thing is that the manufacturer is the same as the other card needing the same quirk. I wonder how many different types are broken this way. The "wrong" ps2_pdac_adj value that comes from BIOS on this card is 0x300. ==================== drm/radeon: Add primary dac adj quirk for Sapphire Radeon VE 7000 DDR Values from BIOS are wrong, causing too bright colors.

2013-10-01drm/radeon/atom: workaround vbios bug in transmitter table on rs880 (v2)Alex Deucher
commit 91f3a6aaf280294b07c05dfe606e6c27b7ba3c72 upstream. The OUTPUT_ENABLE action jumps past the point in the coder where the data_offset is set on certain rs780 cards. This worked previously because the OUTPUT_ENABLE action is always called immediately after the ENABLE action so the data_offset remained set. In 6f8bbaf568c7f2c497558bfd04654c0b9841ad57 (drm/radeon/atom: initialize more atom interpretor elements to 0), we explictly reset data_offset to 0 between atom calls which then caused this to fail. The fix is to just skip calling the OUTPUT_ENABLE action on the problematic chipsets. The ENABLE action does the same thing and more. Ultimately, we could probably drop the OUTPUT_ENABLE action all together on DCE3 asics. fixes: https://bugzilla.kernel.org/show_bug.cgi?id=60791 v2: only rs880 seems to be affected Signed-off-by: Alex Deucher <alexander.deucher@amd.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
