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.

git://git.kernel.org/pub/scm/linux/kernel/git/ebiederm/user-namespace Pull user namespace changes from Eric Biederman: "This is a mostly modest set of changes to enable basic user namespace support. This allows the code to code to compile with user namespaces enabled and removes the assumption there is only the initial user namespace. Everything is converted except for the most complex of the filesystems: autofs4, 9p, afs, ceph, cifs, coda, fuse, gfs2, ncpfs, nfs, ocfs2 and xfs as those patches need a bit more review. The strategy is to push kuid_t and kgid_t values are far down into subsystems and filesystems as reasonable. Leaving the make_kuid and from_kuid operations to happen at the edge of userspace, as the values come off the disk, and as the values come in from the network. Letting compile type incompatible compile errors (present when user namespaces are enabled) guide me to find the issues. The most tricky areas have been the places where we had an implicit union of uid and gid values and were storing them in an unsigned int. Those places were converted into explicit unions. I made certain to handle those places with simple trivial patches. Out of that work I discovered we have generic interfaces for storing quota by projid. I had never heard of the project identifiers before. Adding full user namespace support for project identifiers accounts for most of the code size growth in my git tree. Ultimately there will be work to relax privlige checks from "capable(FOO)" to "ns_capable(user_ns, FOO)" where it is safe allowing root in a user names to do those things that today we only forbid to non-root users because it will confuse suid root applications. While I was pushing kuid_t and kgid_t changes deep into the audit code I made a few other cleanups. I capitalized on the fact we process netlink messages in the context of the message sender. I removed usage of NETLINK_CRED, and started directly using current->tty. Some of these patches have also made it into maintainer trees, with no problems from identical code from different trees showing up in linux-next. After reading through all of this code I feel like I might be able to win a game of kernel trivial pursuit."

2012-10-02drm: support for rotated scanoutRob Clark
For drivers that can support rotated scanout, the extra parameter checking in drm-core, while nice, tends to get confused. To solve this drivers can set the crtc or plane invert_dimensions field so that the dimension checking takes into account the rotation that the driver is performing. v1: original v2: remove invert_dimensions from plane, at Ville's suggestion. Userspace can give rotated src coordinates, so invert_dimensions is not required for planes.

2012-10-02drm: refcnt drm_framebuffer (v4.1)Rob Clark
This simplifies drm fb lifetime, and if the crtc/plane needs to hold a ref to the fb when disabling a pipe until the next vblank, this avoids the need to make disabling an overlay synchronous. This is a problem that shows up when userspace is using a drm plane to implement a hw cursor.. making overlay disable synchronous causes a performance problem when x11 is rapidly enabling/disabling the hw cursor. But not making it synchronous opens up a race condition for crashing if userspace turns around and immediately deletes the fb. Refcnt'ing the fb makes it possible to solve this problem. v1: original v2: add drm_framebuffer_remove() which is called in all paths where fb->funcs->destroy() was directly called before. This cleans up the CRTCs/planes that the fb was attached to. You should only directly use drm_framebuffer_unreference() if you are also using drm_framebuffer_reference() to keep a ref to the fb. v3: add comment explaining the fb refcount v4: remove duplicate 'list_del(&fb->filp_head)' [airlied: v4.1: fix local rejection] Signed-off-by: Rob Clark <rob@ti.com> Signed-off-by: Dave Airlie <airlied@redhat.com>

Note that this doesn't show up in git's merge diff (and hence is also not handled by git rerere), which adds to the reasons why I'd like to fix this with a verbose backmerge.

2012-09-20drm/i915: Replace the array of pages with a scatterlistChris Wilson
Rather than have multiple data structures for describing our page layout in conjunction with the array of pages, we can migrate all users over to a scatterlist. One major advantage, other than unifying the page tracking structures, this offers is that we replace the vmalloc'ed array (which can be up to a megabyte in size) with a chain of individual pages which helps reduce memory pressure. The disadvantage is that we then do not have a simple array to iterate, or to access randomly. The common case for this is in the relocation processing, which will typically fit within a single scatterlist page and so be almost the same cost as the simple array. For iterating over the array, the extra function call could be optimised away, but in reality is an insignificant cost of either binding the pages, or performing the pwrite/pread. v2: Fix drm_clflush_sg() to not invoke wbinvd as well!

Instead of being useful, it creates confusion about who is responsible for freeing the memory it points to and setting the field to NULL afterwards, leading to memory leaks and dangling pointers. Remove the raw_edid field, and fix drivers as necessary.

2012-08-17drm/i915: implement dma buf begin_cpu_access (v2)Dave Airlie
In order for udl vmap to work properly, we need to push the object into the CPU domain before we start copying the data to the USB device. This along with the udl change avoids userspace explicit mapping to be used. v2: add a flag for userspace to query to know if Intel kernel driver can deal with the vmap flushing properly. In theory udl would need a flag also, but I intend to push the patches very close to each other and other drivers should do the right thing from the start. I've added a test to my intel-gpu-tools prime branch, however testing this is a bit messy since the only way to get udl to vmap is to rendering something. I've tested this with real code as well to make sure it works.

2012-08-08drm/i915: Add I915_GEM_PARAM_HAS_SEMAPHORESChris Wilson
Userspace tries to estimate the cost of ring switching based on whether the GPU and GEM supports semaphores. (If we have multiple rings and no semaphores, userspace assumes that the cost of switching rings between batches is exorbitant and will endeavour to keep the next batch on the active ring - as a coarse approximation to tracking both destination and source surfaces.) Currently userspace has to guess whether semaphores exist based on the chipset generation and the module parameter, i915.semaphores. This is a crude and inaccurate guess as the defaults internally depend upon other chipset features being enabled or disabled, nor does it extend well into the future. By exporting a HAS_SEMAPHORES parameter, we can easily query the driver and obtain an accurate answer.

2012-07-26drm/i915: Export ability of changing cache levels to userspaceChris Wilson
By selecting the cache level (essentially whether or not the CPU snoops any updates to the bo, and on more recent machines whether it resides inside the CPU's last-level-cache) a userspace driver is able to then manage all of its memory within buffer objects, if it so desires. This enables the userspace driver to accelerate uploads and more importantly downloads from the GPU and to able to mix CPU and GPU rendering/activity efficiently.

2012-07-25drm/i915: Return a mask of the active rings in the high word of busy_ioctlChris Wilson
The intention is to help select which engine to use for copies with interoperating clients - such as a GL client making a request to the X server to perform a SwapBuffers, which may require copying from the active GL back buffer to the X front buffer. We choose to report a mask of the active rings to future proof the interface against any changes which may allow for the object to reside upon multiple rings.

2012-07-25drm/i915: add register read IOCTLBen Widawsky
The interface's immediate purpose is to do synchronous timestamp queries as required by GL_TIMESTAMP. The GPU has a register for reading the timestamp but because that would normally require root access through libpciaccess, the IOCTL can provide this service instead. Currently the implementation whitelists only the render ring timestamp register, because that is the only thing we need to expose at this time. v2: make size implicit based on the register offset Add a generation check Reviewed-by: Eric Anholt <eric@anholt.net> Cc: Jacek Lawrynowicz <jacek.lawrynowicz@intel.com> Signed-off-by: Ben Widawsky <ben@bwidawsk.net> [danvet: fixup the ioctl numerb:] Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch>

2012-07-19drm/sis: fixup sis_mm ioctl structsDaniel Vetter
Userspace uses long in quite a few places more than the kernel. Which gives me neat proof that I'm the only guy on this side of the galaxy who ever tried to run glxgears on a 64bit machine with sis graphics on linux. Note that the longs in drm_sis_mem_t aren't aligned properly, so this won't even work with 32bit userspace on 64bit kernel as-is. Hence the patch can't break that, either. Nope, I'm not nuts enough to write the 32bit ioctl compat layer for this and test it with some wine app. Even though hunting the ebay dungeons for a sis card actually supported by the mesa drivers casts some doubts on this ...
