Only those objects pinned to the display have semi-permanent pins of a global nature (other pins are transient within their local vm). Simplify i915_gem_pinned to only show the pertinent information about the pinned objects within the GGTT. v2: i915_gem_gtt_info is still shared with debugfs/i915_gem_gtt, rename i915_gem_pinned to i915_gem_pin_display to better reflect its contents Signed-off-by:

Chris Wilson authored
These two files (i915_gem_active, i915_gem_inactive) no longer give pertinent information since active/inactive tracking is per-vm and so we need the information per-vm. They are obsolete so remove them. Signed-off-by:

With execlists, we have context objects everywhere, not just RCS. So store them for post-mortem debugging. This also has a secondary effect of removing one more unsafe list iteration with using preserved state from the hanging request. And now we can cross-reference the request's context state with that loaded by the GPU. Signed-off-by:

Chris Wilson authored
When capturing the error state, we do not need to know about every address space - just those that are related to the error. We know which context is active at the time, therefore we know which VM are implicated in the error. We can then restrict the VM which we report to the relevant subset. v2: s/i/count_active/ (and similar) Rewrite label generation for "Buffers" Signed-off-by: -

Not only does it make for good documentation and debugging aide, but it is also vital for when we want to unwind requests - such as when throwing away an incomplete request. Signed-off-by:

Closed vma are removed from the obj->vma_list so that they cannot be found by userspace. However, this means that when forcibly unbinding an object, we have to wait upon all rendering to that object first in order for the closed, but active, vma to be reaped and their bindings removed. Reported-by:

Restore the processor state before calling any other functions to ensure per-CPU variables can be used with KASLR memory randomization. Tracing functions use per-CPU variables (GS based on x86) and one was called just before restoring the processor state fully. It resulted in a double fault when both the tracing & the exception handler functions tried to use a per-CPU variable.

nfsd4_lock will take the st_mutex before working with the stateid it gets, but between the time when we drop the cl_lock and take the mutex, the stateid could become unhashed (a'la FREE_STATEID). If that happens the lock stateid returned to the client will be forgotten. Fix this by first moving the st_mutex acquisition into lookup_or_create_lock_state. Then, have it check to see if the lock stateid is still hashed after taking the mutex. If it's not, then put the stateid and try the find/create again. Signed-off-by:

Pull libnvdimm fixes from Dan Williams: - Fix for the nd_blk (NVDIMM Block Window Aperture) driver. A spec clarification requires the driver to mask off reserved bits in status register. This is tagged for -stable back to the v4.2 kernel. - Fix for a kernel crash in the nvdimm unit tests when module loading is interrupted with SIGTERM. Tagged for -stable since validation efforts external to Intel use the unit tests for qualifying backports. - Add a new 'size' sysfs attribute for the BTT (NVDIMM Block Translation Table) driver to make it symmetric with the other namespace personality drivers (PFN and DAX) that provide a size attribute for indicating how much namespace capacity is lost to metadata. The BTT change arrived at the start of the merge window and has appeared in a -next release. It can technically wait for 4.9, but it is small, fixes asymmetry in the libnvdimm-sysfs interface, and something I would have squeezed into the v4.8 pull request had it arrived a few days earlier. * 'libnvdimm-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/nvdimm/nvdimm: tools/testing/nvdimm: fix SIGTERM vs hotplug crash nvdimm, btt: add a size attribute for BTTs libnvdimm, nd_blk: mask off reserved status bits
