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.

It would previously write basically random bits to PCI configuration space... Not very surprising that the GPU tended to stop responding completely. The resulting MCE even froze the whole machine sometimes. Now resetting the GPU after a lockup has at least a fighting chance of succeeding. Cc: stable@vger.kernel.org Signed-off-by:

drm/ttm/dma: Fix accounting error when calling ttm_mem_global_free_page and don't try to free freed pages. The code to figure out how many pages to shrink the pool ends up capping the 'count' at _manager->options.max_size - which is OK. Except that the 'count' is also used when accounting for how many pages are recycled - which we end up with the invalid values. This fixes it by using a different value for the amount of pages to shrink. On top of that we would free the cached page pool - which is nonsense as they are deleted from the pool - so there are no free pages in that pool.. Also we also missed the opportunity to batch the amount of pages to free (similar to how ttm_page_alloc.c does it). This reintroduces the code that was lost during rebasing. Reviewed-by:

Otherwise we are doing redundant work. Especially since the 'unbind' and 'unpopulate' have been merged and nouveau driver ends up calling it quite excessivly.

Virtual address space are per drm client (opener of /dev/drm). Client are in charge of virtual address space, they need to map bo into it by calling DRM_RADEON_GEM_VA ioctl. First 16M of virtual address space is reserved by the kernel. Once using 2 level page table we should be able to have a small vram memory footprint for each pt (there would be one pt for all gart, one for all vram and then one first level for each virtual address space). Plan include using the sub allocator for a common vm page table area and using memcpy to copy vm page table in & out. Or use a gart object and copy things in & out using dma. v2: agd5f fixes: - Add vram base offset for vram pages. The GPU physical address of a vram page is FB_OFFSET + page offset. FB_OFFSET is 0 on discrete cards and the physical bus address of the stolen memory on integrated chips. - VM_CONTEXT1_PROTECTION_FAULT_DEFAULT_ADDR covers all vmid's >= 1 v3: agd5f: - integrate with the semaphore/multi-ring stuff v4: - rebase on top ttm dma & multi-ring stuff - userspace is now in charge of the address space - no more specific cs vm ioctl, instead cs ioctl has a new chunk v5: - properly handle mem == NULL case from move_notify callback - fix the vm cleanup path v6: - fix update of page table to only happen on valid mem placement v7: - add tlb flush for each vm context - add flags to define mapping property (readable, writeable, snooped) - make ring id implicit from ib->fence->ring, up to each asic callback to then do ring specific scheduling if vm ib scheduling function v8: - add query for ib limit and kernel reserved virtual space - rename vm->size to max_pfn (maximum number of page) - update gem_va ioctl to also allow unmap operation - bump kernel version to allow userspace to query for vm support v9: - rebuild page table only when bind and incrementaly depending on bo referenced by cs and that have been moved - allow virtual address space to grow - use sa allocator for vram page table - return invalid when querying vm limit on non cayman GPU - dump vm fault register on lockup v10: agd5f: - Move the vm schedule_ib callback to a standalone function, remove the callback and use the existing ib_execute callback for VM IBs. v11: - rebase on top of lastest Linus v12: agd5f: - remove spurious backslash - set IB vm_id to 0 in radeon_ib_get() v13: agd5f: - fix handling of RADEON_CHUNK_ID_FLAGS v14: - fix va destruction - fix suspend resume - forbid bo to have several different va in same vm v15: - rebase v16: - cleanup left over of vm init/fini v17: agd5f: - cs checker v18: agd5f: - reworks the CS ioctl to better support multiple rings and VM. Rather than adding a new chunk id for VM, just re-use the IB chunk id and add a new flags for VM mode. Also define additional dwords for the flags chunk id to define the what ring we want to use (gfx, compute, uvd, etc.) and the priority. v19: - fix cs fini in weird case of no ib - semi working flush fix for ni - rebase on top of sa allocator changes v20: agd5f: - further CS ioctl cleanups from Christian's comments v21: agd5f: - integrate CS checker improvements v22: agd5f: - final cleanups for release, only allow VM CS on cayman Signed-off-by:

drm_getclient, drm_getstats and drm_getmap (with a few minor adjustments) do not need global mutex, so fix that and make the said ioctls DRM_UNLOCKED. Details: drm_getclient: the only thing that should be protected here is dev->filelist and that is already protected everywhere with dev->struct_mutex. drm_getstats: there is no need for any mutex here because the loop runs through quasi-static (set at load time only) data, and the actual count access is done with atomic_read() drm_getmap already uses dev->struct_mutex to protect dev->maplist, which also used to protect the same structure everywhere else except at three places: * drm_getsarea, which doesn't grab *any* mutex before touching dev->maplist (so no drm_global_mutex doesn't help here either; different issue for a different patch). However, drivers seem to call it only at initialization time so it probably doesn't matter * drm_master_destroy, which is called from drm_master_put, which in turn is protected with dev->struct_mutex everywhere else in drm module, so we are good here too. * drm_getsareactx, which releases the dev->struct_mutex too early, but this patch includes the fix for that. v2: * incorporate comments received from Daniel Vetter * include the (long) explanation above to make it clear what we are doing (and why), also at Daniel Vetter's request * tighten up mutex grab/release locations to only encompass real critical sections, rather than some random code around them Signed-off-by:Ilija Hadzic <ihadzic@research.bell-labs.com> Reviewed-by:

In the pre-gem days with non-existing hangcheck and gpu reset code, this timeout of 3 seconds was pretty important to avoid stuck processes. But now we have the hangcheck code in gem that goes to great length to ensure that the gpu is really dead before declaring it wedged. So there's no need for this timeout anymore. Actually it's even harmful because we can bail out too early (e.g. with xscreensaver slip) when running giant batchbuffers. And our code isn't robust enough to properly unroll any state-changes, we pretty much rely on the gpu reset code cleaning up the mess (like cache tracking, fencing state, active list/request tracking, ...). With this change intel_begin_ring can only fail when the gpu is wedged, and it will return -EAGAIN (like wait_request in case the gpu reset is still outstanding). v2: Chris Wilson noted that on resume timers aren't running and hence we won't ever get kicked out of this loop by the hangcheck code. Use an insanely large timeout instead for the HAS_GEM case to prevent resume bugs from totally hanging the machine. Signed-off-by:

If our semaphore logic gets confused and we have a ring stuck waiting for one, there's a decent chance it'll just execute garbage when being kicked. Also, kicking the ring obscures the place where the error first occured, making error_state decoding much harder. So drop this an let gpu reset handle this mess in a clean fashion. In contrast, kicking rings stuck on MI_WAIT is rather harmless, at worst there'll be a bit of screen-flickering. There's also old broken userspace out there which needs this as a work-around.

These registers are automatically incremented by the hardware during transform feedback to track where the next streamed vertex output should go. Unlike the previous generation, which had a packet for setting the corresponding registers to a defined value, gen7 only has MI_LOAD_REGISTER_IMM to do so. That's a secure packet (since it loads an arbitrary register), so we need to do it from the kernel, and it needs to be settable atomically with the batchbuffer execution so that two clients doing transform feedback don't stomp on each others' state. Instead of building a more complicated interface involcing setting the registers to a specific value, just set them to 0 when asked and userland can tweak its pointers accordingly. Signed-off-by:

Previous to this commit, testing easily reproduced a failure where the seqno would apparently arrive after the IRQ associated with it, with test programs as simple as: for (;;) { glCopyPixels(0, 0, 1, 1); glFinish(); } Various workarounds we've seen for previous generations didn't work to fix this issue, so until new information comes in, replace the IRQ waits on the BLT ring with polling.

So add support for them using the new DRM core sprite support functions. v2: use drm specific fourcc header and defines v3: address Daniel's comments: - don't take struct mutex around register access (only needed for regs in the GT power well) - don't hold struct mutex across vblank waits - fix up update_plane API (pass obj instead of GTT offset) - add interlaced defines for sprite regs - drop unnecessary 'reg' variables - comment double buffered reg flushing Also fix w/h confusion when writing the scaling reg. v4: more fixes, address more comments from Daniel, and include Hai's fix - prevent divide by zero in scaling calculation (Hai Lan) - update to Ville's new DRM_FORMAT_* types - fix sprite watermark handling (calc based on CRTC size, separate from normal display wm) - remove private refcounts now that the fb cleanups handles things v5: add linear surface support v6: remove color key clearing & setting from update_plane For this version, I tested DPMS since it came up in the last review; DPMS off/on works ok when a video player is working under X, but for power saving we'll probably want to do something smarter. I'll leave that for a separate patch on top. Likewise with the refcounting/fb layer handling, which are really separate cleanups. Reviewed-by: -

We learned that the ECOBUS register was inside the GT power well, and so *did* need force wake to be read, so it gets removed from the list of 'doesn't need force wake' registers. That means the code reading ECOBUS after forcing the mt_force_wake function to be called needs to use I915_READ_NOTRACE; it doesn't need to do more force wake fun as it's already done it manually. This also adds a comment explaining why the MT forcewake testing code only needs to call mt_forcewake_get/put and not disable RC6 manually -- the ECOBUS read will return 0 if the device is in RC6 and isn't using MT forcewake, causing the test to work correctly.

Many of the old fields from Ironlake have gone away. Strip all those fields, and try to update to fields people care about. RC information isn't exactly ideal anymore. All we can guarantee when we read the register is that we're not using forcewake, ie. the software isn't forcing the hardware to stay awake. The downside is that in doing this we may wait a while and that causes an unnaturally idle state on the GPU. Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=42578Signed-off-by:

dev_priv keeps track of the current addressing mode that gets set at execbuffer time. Unfortunately the existing code was doing this before acquiring struct_mutex which leaves a race with another thread also doing an execbuffer. If that wasn't bad enough, relocate_slow drops struct_mutex which opens a much more likely error where another thread comes in and modifies the state while relocate_slow is being slow. The solution here is to just defer setting this state until we absolutely need it, and we know we'll have struct_mutex for the remainder of our code path. v2: Keith noticed a bug in the original patch.
