2013-10-22T08:02:25+00:00

commit 50b8f5aec04ebec7dbdf2adb17220b9148c99e63 upstream. They have 4 rather than 8. Fixes: https://bugs.freedesktop.org/show_bug.cgi?id=63599 Signed-off-by: wojciech kapuscinski Signed-off-by: Alex Deucher Signed-off-by: Greg Kroah-Hartman

drm/radeon: disable tests/benchmarks if accel is disabled

2013-10-05T14:06:54+00:00

commit 4a1132a023eb48cf10522d84c5908d43b612c041 upstream. The tests are only usable if the acceleration engines have been successfully initialized. Based on an initial patch from: Alex Ivanov Signed-off-by: Alex Deucher Signed-off-by: Greg Kroah-Hartman

drm/i915/dp: increase i2c-over-aux retry interval on AUX DEFER

2013-10-05T14:06:54+00:00

commit 8d16f258217f2f583af1fd57c5144aa4bbe73e48 upstream. There is no clear cut rules or specs for the retry interval, as there are many factors that affect overall response time. Increase the interval, and even more so on branch devices which may have limited i2c bit rates.

drm/radeon/atom: workaround vbios bug in transmitter table on rs880 (v2)

2013-10-01T16:10:51+00:00

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 Signed-off-by: Greg Kroah-Hartman

drm/radeon: fix handling of variable sized arrays for router objects

2013-10-01T16:10:51+00:00

commit fb93df1c2d8b3b1fb16d6ee9e32554e0c038815d upstream. The table has the following format: typedef struct _ATOM_SRC_DST_TABLE_FOR_ONE_OBJECT //usSrcDstTableOffset pointing to this structure { UCHAR ucNumberOfSrc; USHORT usSrcObjectID[1]; UCHAR ucNumberOfDst; USHORT usDstObjectID[1]; }ATOM_SRC_DST_TABLE_FOR_ONE_OBJECT; usSrcObjectID[] and usDstObjectID[] are variably sized, so we can't access them directly. Use pointers and update the offset appropriately when accessing the Dst members. Signed-off-by: Alex Deucher Signed-off-by: Greg Kroah-Hartman

drm/radeon: fix resume on some rs4xx boards (v2)

2013-10-01T16:10:51+00:00

commit acf88deb8ddbb73acd1c3fa32fde51af9153227f upstream. Setting MC_MISC_CNTL.GART_INDEX_REG_EN causes hangs on some boards on resume. The systems seem to work fine without touching this bit so leave it as is. v2: read-modify-write the GART_INDEX_REG_EN bit. I suspect the problem is that we are losing the other settings in the register. fixes: https://bugs.freedesktop.org/show_bug.cgi?id=52952 Reported-by: Ondrej Zary Tested-by: Daniel Tobias Signed-off-by: Alex Deucher Signed-off-by: Greg Kroah-Hartman

drm/radeon: update line buffer allocation for dce6

2013-10-01T16:10:51+00:00

commit 290d24576ccf1aa0373d2185cedfe262d0d4952a upstream. We need to allocate line buffer to each display when setting up the watermarks. Failure to do so can lead to a blank screen. This fixes blank screen problems on dce6 asics.

drm/radeon: fix endian bugs in hw i2c atom routines

2013-10-01T16:10:51+00:00

commit 4543eda52113d1e2cc0e9bf416f79597e6ef1ec7 upstream. 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 Signed-off-by: Greg Kroah-Hartman

drm/radeon: fix LCD record parsing

2013-10-01T16:10:51+00:00

commit 95663948ba22a4be8b99acd67fbf83e86ddffba4 upstream. If the LCD table contains an EDID record, properly account for the edid size when walking through the records. This should fix error messages about unknown LCD records. Signed-off-by: Alex Deucher Signed-off-by: Greg Kroah-Hartman
