As i915_gem_reset_finish() undoes the steps from i915_gem_reset_prepare() to leave the system in a fully-working state, e.g. to be able to free the breadcrumb signal threads, make sure that we always call it even on the error path.

On Baytrail, we manually calculate busyness over the evaluation interval to avoid issues with miscaluations with RC6 enabled. However, it turns out that the DOWN_EI interrupt generator is completely bust - it operates in two modes, continuous or never. Neither of which are conducive to good behaviour. Stop unmask the DOWN_EI interrupt and just compute everything from the UP_EI which does seem to correspond to the desired interval. v2: Fixup gen6_rps_pm_mask() as well v3: Inline vlv_c0_above() to combine the now identical elapsed calculation for up/down and simplify the threshold testing Fixes: 43cf3bf0 ("drm/i915: Improved w/a for rps on Baytrail") Signed-off-by:

This patch makes the I915_PARAM_HAS_EXEC_CONSTANTS getparam return 0 (indicating the optional feature is not supported), and makes execbuf always return -EINVAL if the flags are used. Apparently, no userspace ever shipped which used this optional feature: I checked the git history of Mesa, xf86-video-intel, libva, and Beignet, and there were zero commits showing a use of these flags. Kernel commit 72bfa19c apparently introduced the feature prematurely. According to Chris, the intention was to use this in cairo-drm, but "the use was broken for gen6", so I don't think it ever happened. 'relative_constants_mode' has always been tracked per-device, but this has actually been wrong ever since hardware contexts were introduced, as the INSTPM register is saved (and automatically restored) as part of the render ring context. The software per-device value could therefore get out of sync with the hardware per-context value. This meant that using them is actually unsafe: a client which tried to use them could damage the state of other clients, causing the GPU to interpret their BO offsets as absolute pointers, leading to bogus memory reads. These flags were also never ported to execlist mode, making them no-ops on Gen9+ (which requires execlists), and Gen8 in the default mode. On Gen8+, userspace can write these registers directly, achieving the same effect. On Gen6-7.5, it likely makes sense to extend the command parser to support them. I don't think anyone wants this on Gen4-5. Based on a patch by Dave Gordon. v3: Return -ENODEV for the getparam, as this is what we do for other obsolete features. Suggested by Chris Wilson.

When we restart the engines, and we have active requests, a request on the first engine may complete and queue a request to the second engine before we try to restart the second engine. That queueing of the request may race with the engine to restart, and so may corrupt the current state. Disabling the engine->irq_tasklet prevents the two paths from writing into ELSP simultaneously (and modifyin the execlists_port[] at the same time).

Currently we do a reset prepare/finish around the call to reset the GPU, but it looks like we need a later stage after the hw has been reinitialised to allow GEM to restart itself. Start by splitting the 2 GEM phases into 3: prepare - before the reset, check if GEM recovered, then stop GEM reset - after the reset, update GEM bookkeeping finish - after the re-initialisation following the reset, restart GEM Signed-off-by:

It looks like we were incorrectly comparing vma->node against itself instead of the target node, when evicting for a node on systems where we need guard pages between regions with different cache domains. As a consequence we can end up trying to needlessly evict neighbouring nodes, even if they have the same cache domain, and if they were pinned we would fail the eviction.

If we have any residual freed atomic state from earlier commits, flush the freed list after performing the current modeset.

Before we instantiate/pin the backing store for our use, we can prepopulate the shmemfs filp efficiently using a write into the pagecache. We avoid the penalty of instantiating all the pages, important if the user is just writing to a few and never uses the object on the GPU, and using a direct write into shmemfs allows it to avoid the cost of retrieving a page (mostly the clear-before-use, but in theory we could curtail swapin) before it is overwritten. This can be extended later to provide additional specialisation for other backends (other than shmemfs). For now it provides a defense against very large write-only allocations from exhausting all of system memory. v2: Smelling fixes.

Certain Baytrails, namely the 4 cpu core variants, have been plaqued by spurious system hangs, mostly occurring with light loads. Multiple bisects by various people point to a commit which changes the reclocking strategy for Baytrail to follow its bigger brethen: commit 8fb55197 ("drm/i915: Agressive downclocking on Baytrail") There is also a review comment attached to this commit from Deepak S on avoiding punit access on Cherryview and thus it was excluded on common reclocking path. By taking the same approach and omitting the punit access by not tweaking the thresholds when the hardware has been asked to move into different frequency, considerable gains in stability have been observed. With J1900 box, light render/video load would end up in system hang in usually less than 12 hours. With this patch applied, the cumulative uptime has now been 34 days without issues. To provoke system hang, light loads on both render and bsd engines in parallel have been used: glxgears >/dev/null 2>/dev/null & mpv --vo=vaapi --hwdec=vaapi --loop=inf vid.mp4 So far, author has not witnessed system hang with above load and this patch applied. Reports from the tenacious people at kernel bugzilla are also promising. Considering that the punit access frequency with this patch is considerably less, there is a possibility that this will push the, still unknown, root cause past the triggering point on most loads. But as we now can reliably reproduce the hang independently, we can reduce the pain that users are having and use a static thresholds until a root cause is found. v3: don't break debugfs and simplification (Chris Wilson) References: https://bugzilla.kernel.org/show_bug.cgi?id=109051 Cc: Chris Wilson <chris@chris-wilson.co.uk> Cc: Ville Syrjälä <ville.syrjala@linux.intel.com> Cc: Len Brown <len.brown@intel.com> Cc: Daniel Vetter <daniel.vetter@ffwll.ch> Cc: Jani Nikula <jani.nikula@intel.com> Cc: fritsch@xbmc.org Cc: miku@iki.fi Cc: Ezequiel Garcia <ezequiel@vanguardiasur.com.ar> CC: Michal Feix <michal@feix.cz> Cc: Hans de Goede <hdegoede@redhat.com> Cc: Deepak S <deepak.s@linux.intel.com> Cc: Jarkko Nikula <jarkko.nikula@linux.intel.com> Cc: <stable@vger.kernel.org> # v4.2+ Acked-by:

Per PCI specification, Configuration Register has different types (RO, RW, RW1C, Rsvd). For RO Register bits are read-only and cannot be altered by software. For RW1C Register bits indicate status when read. A Set bit indicates a status event which is Cleared by writing a 1b. Writing a 0b to RW1C bits has no effect. Reserved Register is for future implementations, and they are read-only and must return zero when read. Current vGPU configuration write emulation just copy the value as it is. So we haven't emulated RO, RW1C and Rsvd Registers correctly. This patch is following the Spec to correct emulation logic. We add a function vgpu_cfg_mem_write to wrap the access to vGPU configuration memory. The write function uses a RW Register bitmap to avoid RO bits be overwritten, and emulate RW1C behavior for the particular status Register. v2: new = src[i] --> new = src[i] & mask (zhenyu) Signed-off-by:

With this mechanism, gvt should wait until the GVT request seqno passed before complete the current workload. So that there should be a context switch interrupt come before gvt free the workload. In this way, workload lifecylce matches with the i915 request lifecycle.

Pull libnvdimm fixes from Dan Williams: "A fix and regression test case for nvdimm namespace label compatibility. Details: - An "nvdimm namespace label" is metadata on an nvdimm that provisions dimm capacity into a "namespace" that can host a block device / dax-filesytem, or a device-dax character device. A namespace is an object that other operating environment and platform firmware needs to comprehend for capabilities like booting from an nvdimm. The label metadata contains a checksum that Linux was not calculating correctly leading to other environments rejecting the Linux label. These have received a build success notification from the kbuild robot, and a positive test result from Nick who reported the problem" * 'libnvdimm-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/nvdimm/nvdimm: nfit, libnvdimm: fix interleave set cookie calculation tools/testing/nvdimm: make iset cookie predictable -
