2014-01-29drm/radeon/DCE4+: clear bios scratch dpms bit (v2)Alex Deucher1-0/+4
The BlankCrtc table in some DCE8 boards has some logic shortcuts for the vbios when this bit is set. Clear it for driver use. v2: fix typo Bug: https://bugs.freedesktop.org/show_bug.cgi?id=73420 Signed-off-by: Alex Deucher <alexander.deucher@amd.com> Cc: stable@vger.kernel.org
2014-01-22Merge branch 'drm-vbl-timestamp' of git://gitorious.org/vsyrjala/linux into drm-nextDave Airlie1-2/+4
Here's the vblank timestamp pull request you wanted. I addressed the few bugs that Mario pointed out and added the r-bs. As it has been a while since I made the changes, I gave it a quick spin on a few different i915 machines. Fortunately everything still seems to be fine. * 'drm-vbl-timestamp' of git://gitorious.org/vsyrjala/linux: drm/i915: Add a kludge for DSL incrementing too late and ISR not working drm/radeon: Move the early vblank IRQ fixup to radeon_get_crtc_scanoutpos() drm: Pass 'flags' from the caller to .get_scanout_position() drm: Fix vblank timestamping constants for interlaced modes drm/i915: Fix scanoutpos calculations for interlaced modes drm: Change {pixel,line,frame}dur_ns from s64 to int drm: Use crtc_clock in drm_calc_timestamping_constants() drm/radeon: Populate crtc_clock in radeon_atom_get_tv_timings() drm: Simplify the math in drm_calc_timestamping_constants() drm: Improve drm_calc_timestamping_constants() documentation drm/i915: Call drm_calc_timestamping_constants() earlier drm/i915: Kill hwmode save/restore drm: Pass the display mode to drm_calc_vbltimestamp_from_scanoutpos() drm: Pass the display mode to drm_calc_timestamping_constants()

2014-01-20drm/radeon: Populate crtc_clock in radeon_atom_get_tv_timings()Ville Syrjälä1-2/+4
crtc_clock is now supposed to be the actual pixel clock corresponding to the other crtc_ timing values. Populate crtc_clock appropriately in radeon_atom_get_tv_timings(). This was the only obvious place where we frob with the crtc_ timigns directly instead of calling drm_mode_set_crtcinfo() which would also update crtc_clock.

Newer versions of gcc seem to wander off into the weeds when dealing with variable sizes arrays in structs. Rather than indexing the arrays, use pointer arithmetic. Fix up spread spectrum tables.

Pull drm merge (part 1) from Dave Airlie: "So first of all my tree and uapi stuff has a conflict mess, its my fault as the nouveau stuff didn't hit -next as were trying to rebase regressions out of it before we merged. Highlights: - SH mobile modesetting driver and associated helpers - some DRM core documentation - i915 modesetting rework, haswell hdmi, haswell and vlv fixes, write combined pte writing, ilk rc6 support, - nouveau: major driver rework into a hw core driver, makes features like SLI a lot saner to implement, - psb: add eDP/DP support for Cedarview - radeon: 2 layer page tables, async VM pte updates, better PLL selection for > 2 screens, better ACPI interactions The rest is general grab bag of fixes. So why part 1? well I have the exynos pull req which came in a bit late but was waiting for me to do something they shouldn't have and it looks fairly safe, and David Howells has some more header cleanups he'd like me to pull, that seem like a good idea, but I'd like to get this merge out of the way so -next dosen't get blocked."
