drm/edid: set ELD for firmware and debugfs override EDIDs

2015-03-27T11:27:04Z

If the user supplies EDID through firmware or debugfs override, the driver callbacks are bypassed and the connector ELD does not get updated, and audio fails. Set ELD for firmware and debugfs EDIDs too. There should be no harm in gratuitously doing this for non HDMI/DP connectors, as it's still up to the driver to use the ELD, if any.

drm/edid: Deletion of an unnecessary check before the function call "release_firmware"

2014-11-21T02:16:27Z

The release_firmware() function tests whether its argument is NULL and then returns immediately. Thus the test around the call is not needed. This issue was detected by using the Coccinelle software. Signed-off-by: Markus Elfring Reviewed-by: Thierry Reding Signed-off-by: Dave Airlie

drm: Add 800x600 (SVGA) screen resolution to the built-in EDIDs

2014-05-26T02:53:40Z

The 800x600 (SVGA) screen resolution was lacking in the set of built-in selectable EDID screen resolutions that can be used to repair misbehaving monitor firmware. This patch adds the related data set and expands the documentation. Note that the SVGA bit occupies a different byte to all the existing users of the established timing bits forcing a rework of the ESTABLISHED_TIMINGS_BITS macro. Tested new EDID on an aged (and misbehaving) industrial LCD panel; existing EDIDs still pass edid-decode's checksum checks.

drm/edid: Make edid_load() return a void *

2013-12-18T00:42:13Z

Always use "void *" for arbitrary memory buffers, as this allows to drop casts in assignments. Signed-off-by: Geert Uytterhoeven Reviewed-by: Alex Deucher Signed-off-by: Dave Airlie

drm: Try loading builtin EDIDs first

2013-10-09T05:55:28Z

If the firmware is not builtin and userspace is not yet running, we can stall the boot process for a minute whilst the firmware loader times out. This is contrary to expectations of providing a builtin EDID! In the process, we can rearrange the code to make the error handling more resilient and prevent gcc warning about unitialised variables along the error paths. v2: Load builtins first, fix gcc second (Jani) and cosmetics (Ville). v3: Verify that we do not read beyond the end of the fwdata (Ville) Signed-off-by: Chris Wilson Cc: Ville Syrjälä Cc: Jani Nikula Reviewed-by: Jani Nikula Signed-off-by: Dave Airlie

Merge branch 'drm-next' of git://people.freedesktop.org/~airlied/linux

2012-10-04T06:29:23Z

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." Tons of conflicts mostly due to silly include line changes, but mostly mindless. A few other small semantic conflicts too, noted from Dave's pre-merged branch. * 'drm-next' of git://people.freedesktop.org/~airlied/linux: (447 commits) drm/nv98/crypt: fix fuc build with latest envyas drm/nouveau/devinit: fixup various issues with subdev ctor/init ordering drm/nv41/vm: fix and enable use of "real" pciegart drm/nv44/vm: fix and enable use of "real" pciegart drm/nv04/dmaobj: fixup vm target handling in preparation for nv4x pcie drm/nouveau: store supported dma mask in vmmgr drm/nvc0/ibus: initial implementation of subdev drm/nouveau/therm: add support for fan-control modes drm/nouveau/hwmon: rename pwm0* to pmw1* to follow hwmon's rules drm/nouveau/therm: calculate the pwm divisor on nv50+ drm/nouveau/fan: rewrite the fan tachometer driver to get more precision, faster drm/nouveau/therm: move thermal-related functions to the therm subdev drm/nouveau/bios: parse the pwm divisor from the perf table drm/nouveau/therm: use the EXTDEV table to detect i2c monitoring devices drm/nouveau/therm: rework thermal table parsing drm/nouveau/gpio: expose the PWM/TOGGLE parameter found in the gpio vbios table drm/nouveau: fix pm initialization order drm/nouveau/bios: check that fixed tvdac gpio data is valid before using it drm/nouveau: log channel debug/error messages from client object rather than drm client drm/nouveau: have drm debugging macros build on top of core macros ...
