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 ...

| | | | | | | | | | | | | | | | To have DP behave like VGA/DVI we need to retrain the link on hotplug.

|\ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Conflicts: drivers/gpu/drm/i915/intel_display.c Ok, this is a fun story of git totally messing things up. There /shouldn't/ be any conflict in here, because the fixes in -rc6 do only touch functions that have not been changed in -next. The offending commits in drm-next are 14415745b2..1fa611065 which simply move a few functions from intel_display.c to intel_pm.c. The problem seems to be that git diff gets completely confused: $ git diff 14415745b2..1fa611065 is a nice mess in intel_display.c, and the diff leaks into totally unrelated functions, whereas $git diff --minimal 14415745b2..1fa611065 is exactly what we want. Unfortunately there seems to be no way to teach similar smarts to the merge diff and conflict generation code, because with the minimal diff there really shouldn't be any conflicts. For added hilarity, every time something in that area changes the + and - lines in the diff move around like crazy, again resulting in new conflicts. So I fear this mess will stay with us for a little longer (and might result in another backmerge down the road). Signed-Off-by: Daniel Vetter <daniel.vetter@ffwll.ch>

* drm/radeon: Allow panel preferred EDID to override BIOS native modeMatthew Garrett2011-08-121-2/+11
| | | | | | | | | | | | | | | | | We have two sources of information about panel capabilities on mobile radeon - the BIOS, which gives us a native mode, and the panel's preferred mode. In theory these two will always match, but there's some corner cases where the BIOS hasn't been fully initialised and so the native mode in it ends up with default values. However, if we get a panel with reasonable EDID, it's probably the case that the panel's preferred mode does actually represent the panel capabilities. This patch handles that case by replacing the native mode with the panel's preferred mode if the resolutions don't match. Systems without a valid internal panel EDID will still use the BIOS native mode.

* drm/radeon: Extended DDC Probing for Connectors with Improperly Wired DDC ↵Thomas Reim2011-08-041-3/+42
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Lines (here: Asus M2A-VM HDMI) Some integrated ATI Radeon chipset implementations with add-on HDMI card (e. g. Asus M2A-VM HDMI) indicate the availability of a DDC even when the add-on card is not plugged in or HDMI is disabled in BIOS setup. In this case, drm_get_edid() and drm_edid_block_valid() periodically dump data and kernel errors into system log files and onto terminals. For these connectors DDC probing is extended by a check for a correct EDID header. Only in case a valid EDID header is also found, the (HDMI or DVI) connector will be used by the Radeon driver. This prevents the kernel driver from useless flooding of logs and terminal sessions with EDID dumps and error messages. This patch adds a flag 'requires_extended_probe' to the radeon_connector structure. In function radeon_connector_needs_extended_probe() this flag can be set on a chipset family/vendor/connector type specific basis. In addition, function radeon_ddc_probe() has been adapted to perform extended DDC probing if required by the connector's flag. Requires function drm_edid_header_is_valid() in DRM module provided by [PATCH] drm: Separate EDID Header Check from EDID Block Check.

* drm/radeon/kms: add connectors even if i2c failsAlex Deucher2011-04-151-17/+12
| | | | | | | | | | | | | | | | | | | | | Sometimes the i2c test in i2c_bit_add_bus fails if this happens we fail to register the i2c adapter and eventually fail to add the connector. If i2c fails, add the connector to the user can at least force it on. Note that some distros set i2c-algo-bit.bit_test to 1 by default which sometimes fails preventing the ddc i2c adapter from being added. The i2c adapter works even if the bit test fails, probably due to pre/post_xfer not getting called in the test_bit function. I have another patch to follow up on that.

| * drm/radeon/kms: fix hardcoded EDID handlingAlex Deucher2011-03-241-2/+28
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On some servers there is a hardcoded EDID provided in the vbios so that the driver will always see a display connected even if something like a KVM prevents traditional means like DDC or load detection from working properly. Also most server boards with DVI are not actually DVI, but DVO connected to a virtual KVM service processor. If we fail to detect a monitor via DDC or load detection and a hardcoded EDID is available, use it. Additionally, when using the hardcoded EDID, use a copy of it rather than the actual one stored in the driver as the detect() and get_modes() functions may free it if DDC is successful. This fixes the virtual KVM on several internal servers. Signed-off-by: Alex Deucher <alexdeucher@gmail.com> Cc: stable@kernel.org Signed-off-by: Dave Airlie <airlied@redhat.com>
