Pull drm update from Dave Airlie: "This pull just contains a forward of the Intel fixes from Daniel. The only annoyance is the RC6 enable, which really should have made -next, but since Ubuntu are shipping it I reckon its getting a good testing now by the time 3.4 comes out. The pull from Daniel contains his pull message to me: "A few patches for 3.4, major part is 3 regression fixes: - ppgtt broke hibernate on snb/ivb. Somehow our QA claims that it still works, which is why this has not been caught earlier. - ppgtt flails in combination with dmar. I kinda expected this one :( - fence handling bugfix for gen2/3. Iirc this one is about a year old, fix curtesy Chris Wilson. I've created an shockingly simple i-g-t test to catch this in the future." Wrt regressions I've just got a report that gmbus (newly enabled again in 3.4) is a bit noisy. I'm looking into this atm. Also included are the rc6 enable patches for snb from Eugeni. I wanted to include these in the main 3.4 pull but screwed it up. Please hit me. Imo these kind of patches really should go in before -rc1, but in thise case rc6 has brought us tons of press and guinea pigs^W^W testers and ubuntu is already running with it. So I estimate a pretty small chance for this to blow up. And some smaller things: - two minor locking snafus - server gt2 ivb pciid - 2 patches to sanitize the register state left behind by the bios some more - 2 new quirk entries - cs readback trick against missed IRQs from ivb also enabled on snb - sprite fix from Jesse" Let's see if the "enable RC6 on sandybridge" finally works and sticks. I've been enabling it by hand (i915.i915_enable_rc6=1) for several months on my Macbook Air, and it definitely makes a difference (and has worked for me). But every time we enabled it before it showed some odd hw buglet for *somebody*. This time it's all good, I'm sure. * 'drm-fixes-intel' of git://people.freedesktop.org/~airlied/linux: drm/i915: treat src w & h as fixed point in sprite handling code drm/i915: no-lvds quirk on MSI DC500 drm/i915: Add lock on drm_helper_resume_force_mode drm/i915: don't leak struct_mutex lock on ppgtt init failures drm/i915: disable ppgtt on snb when dmar is enabled drm/i915: add Ivy Bridge GT2 Server entries drm/i915: properly clear SSC1 bit in the pch refclock init code drm/i915: apply CS reg readback trick against missed IRQ on snb drm/i915: quirk away broken OpRegion VBT drm/i915: enable plain RC6 on Sandy Bridge by default drm/i915: allow to select rc6 modes via kernel parameter drm/i915: Mark untiled BLT commands as fenced on gen2/3 drm/i915: properly restore the ppgtt page directory on resume drm/i915: Sanitize BIOS debugging bits from PIPECONF

2012-03-30drm: base prime/dma-buf support (v5)Dave Airlie
This adds the basic drm dma-buf interface layer, called PRIME. This commit doesn't add any driver support, it is simply and agreed upon starting point so we can work towards merging driver support for the next merge window. Current drivers with work done are nouveau, i915, udl, exynos and omap. The main APIs exposed to userspace allow translating a 32-bit object handle to a file descriptor, and a file descriptor to a 32-bit object handle. The flags value is currently limited to O_CLOEXEC. Acknowledgements: Daniel Vetter: lots of review Rob Clark: cleaned up lots of the internals and did lifetime review. v2: rename some functions after Chris preferred a green shed fix IS_ERR_OR_NULL -> IS_ERR v3: Fix Ville pointed out using buffer + kmalloc v4: add locking as per ickle review v5: allow re-exporting the original dma-buf (Daniel) Reviewed-by: Daniel Vetter <daniel.vetter@ffwll.ch> Reviewed-by: Rob Clark <rob.clark@linaro.org> Reviewed-by: Sumit Semwal <sumit.semwal@linaro.org> Reviewed-by: Inki Dae <inki.dae@samsung.com> Acked-by: Ben Widawsky <benjamin.widawsky@intel.com> Signed-off-by: Dave Airlie <airlied@redhat.com>

git://git.kernel.org/pub/scm/linux/kernel/git/paulg/linux Pull <linux/bug.h> cleanup from Paul Gortmaker: "The changes shown here are to unify linux's BUG support under the one <linux/bug.h> file. Due to historical reasons, we have some BUG code in bug.h and some in kernel.h -- i.e. the support for BUILD_BUG in linux/kernel.h predates the addition of linux/bug.h, but old code in kernel.h wasn't moved to bug.h at that time. As a band-aid, kernel.h was including <asm/bug.h> to pseudo link them. This has caused confusion[1] and general yuck/WTF[2] reactions. Here is an example that violates the principle of least surprise: CC lib/string.o lib/string.c: In function 'strlcat': lib/string.c:225:2: error: implicit declaration of function 'BUILD_BUG_ON' make[2]: *** [lib/string.o] Error 1 $ $ grep linux/bug.h lib/string.c #include <linux/bug.h> $ We've included <linux/bug.h> for the BUG infrastructure and yet we still get a compile fail! [We've not kernel.h for BUILD_BUG_ON.] Ugh - very confusing for someone who is new to kernel development. With the above in mind, the goals of this changeset are: 1) find and fix any include/*.h files that were relying on the implicit presence of BUG code. 2) find and fix any C files that were consuming kernel.h and hence relying on implicitly getting some/all BUG code. 3) Move the BUG related code living in kernel.h to <linux/bug.h> 4) remove the asm/bug.h from kernel.h to finally break the chain. During development, the order was more like 3-4, build-test, 1-2. But to ensure that git history for bisect doesn't get needless build failures introduced, the commits have been reorderd to fix the problem areas in advance.

2012-03-21drm/radeon/kms: add support for the CONST IB to the CS ioctlAlex Deucher
This adds a new chunk id to the CS ioctl to support the INDIRECT_BUFFER_CONST packet. On SI, the CP adds a new engine called the CE (Constant Engine) which runs simulatenously with the DE (Drawing Engine, formerly called the ME). This allows the CP to process two related IBs simultaneously. The CE is tasked with loading the constant data (constant buffers, resource descriptors, samplers, etc.) while the DE loads context register state and issues drawing commands. It's up to the userspace application to sychronize the CE and the DE using special synchronization packets.

2012-03-20drm: allow loading an EDID as firmware to override broken monitorCarsten Emde
Broken monitors and/or broken graphic boards may send erroneous or no EDID data. This also applies to broken KVM devices that are unable to correctly forward the EDID data of the connected monitor but invent their own fantasy data. This patch allows to specify an EDID data set to be used instead of probing the monitor for it. It contains built-in data sets of frequently used screen resolutions. In addition, a particular EDID data set may be provided in the /lib/firmware directory and loaded via the firmware interface. The name is passed to the kernel as module parameter of the drm_kms_helper module either when loaded options drm_kms_helper edid_firmware=edid/1280x1024.bin or as kernel commandline parameter drm_kms_helper.edid_firmware=edid/1280x1024.bin It is also possible to restrict the usage of a specified EDID data set to a particular connector. This is done by prepending the name of the connector to the name of the EDID data set using the syntax edid_firmware=[<connector>:]<edid> such as, for example, edid_firmware=DVI-I-1:edid/1920x1080.bin in which case no other connector will be affected. The built-in data sets are Resolution Name -------------------------------- 1024x768 edid/1024x768.bin 1280x1024 edid/1280x1024.bin 1680x1050 edid/1680x1050.bin 1920x1080 edid/1920x1080.bin They are ignored, if a file with the same name is available in the /lib/firmware directory. The built-in EDID data sets are based on standard timings that may not apply to a particular monitor and even crash it. Ideally, EDID data of the connected monitor should be used. They may be obtained through the drm/cardX/cardX-<connector>/edid entry in the /sys/devices PCI directory of a correctly working graphics adapter. It is even possible to specify the name of an EDID data set on-the-fly via the /sys/module interface, e.g. echo edid/myedid.bin >/sys/module/drm_kms_helper/parameters/edid_firmware The new screen mode is considered when the related kernel function is called for the first time after the change. Such calls are made when the X server is started or when the display settings dialog is opened in an already running X server.

The actual feature work to support interlaced depends upon (and conflicts with) this bugfix. - forcewake voodoo to workaround missed IRQ issues: -fixes only enabled this for ivybridge, but some recent bug reports indicate that we need this on Sandybridge, too.

2012-02-03drm: add proper return value for drm_mode_crtc_set_gamma_sizeSascha Hauer
drm_mode_crtc_set_gamma_size returns boolean true for success and false for failure. This is not very kernel conform, so change it to return 0 for success and a propert error code otherwise. Noone checks the return value, so no users have to be fixed. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de> Signed-off-by: Dave Airlie <airlied@redhat.com>
2012-01-25drm: Fix authentication kernel crashThomas Hellstrom
If the master tries to authenticate a client using drm_authmagic and that client has already closed its drm file descriptor, either wilfully or because it was terminated, the call to drm_authmagic will dereference a stale pointer into kmalloc'ed memory and corrupt it. Typically this results in a hard system hang. This patch fixes that problem by removing any authentication tokens (struct drm_magic_entry) open for a file descriptor when that file descriptor is closed.

2012-01-06drm: introduce drm_can_sleep and use in intel/radeon drivers. (v2)Dave Airlie
So we have a few places where the drm drivers would like to sleep to be nice to the system, mainly in the modesetting paths, but we also have two cases were atomic modesetting must take place, panic writing and kernel debugger. So provide a central inline to determine if a sleep or delay should be used and use this in the intel and radeon drivers. v2: drop intel_drv.h MSLEEP macro, nobody uses it.
