drm/radeon: Always store CRTC relative radeon_crtc->cursor_x/y values

2017-01-12T10:22:51+00:00

commit 4349bd775cc8fd75cb648e3a2036a690f497de5c upstream. We were storing viewport relative coordinates for AVIVO/DCE display engines. However, radeon_crtc_cursor_set2 and radeon_cursor_reset pass radeon_crtc->cursor_x/y as the x/y parameters of radeon_cursor_move_locked, which would break if the CRTC isn't located at (0, 0).

drivers/gpu/drm/ast: Fix infinite loop if read fails

2017-01-09T07:07:46+00:00

commit 298360af3dab45659810fdc51aba0c9f4097e4f6 upstream. ast_get_dram_info() configures a window in order to access BMC memory. A BMC register can be configured to disallow this, and if so, causes an infinite loop in the ast driver which renders the system unusable. Fix this by erroring out if an error is detected. On powerpc systems with EEH, this leads to the device being fenced and the system continuing to operate.

drm/gma500: Add compat ioctl

2017-01-09T07:07:46+00:00

commit 0a97c81a9717431e6c57ea845b59c3c345edce67 upstream. Hook up drm_compat_ioctl to support 32-bit userspace on 64-bit kernels. It turns out that N2600 and N2800 comes with 64-bit enabled. We previously assumed there where no such systems out there.

drm/nouveau/i2c/gk110b,gm10x: use the correct implementation

commit 5b3800a6b763874e4a23702fb9628d3bd3315ce9 upstream. DPAUX registers moved on Kepler, these chipsets were still using the Fermi implementation for some reason. This fixes detection of hotplug/sink IRQs on DP connectors. Signed-off-by: Ben Skeggs Signed-off-by: Greg Kroah-Hartman

drm/nouveau/fifo/gf100-: protect channel preempt with subdev mutex

2017-01-09T07:07:45+00:00

commit b27add13f500469127afdf011dbcc9c649e16e54 upstream. This avoids an issue that occurs when we're attempting to preempt multiple channels simultaneously. HW seems to ignore preempt requests while it's still processing a previous one, which, well, makes sense. Fixes random "fifo: SCHED_ERROR 0d []" + GPCCS page faults during parallel piglit runs on (at least) GM107. Signed-off-by: Ben Skeggs Signed-off-by: Greg Kroah-Hartman
