2019-11-05drm/i915/gen8+: Add RC6 CTX corruption WAImre Deak1-2/+6
In some circumstances the RC6 context can get corrupted. We can detect this and take the required action, that is disable RC6 and runtime PM. The HW recovers from the corrupted state after a system suspend/resume cycle, so detect the recovery and re-enable RC6 and runtime PM. v2: rebase (Mika) v3: - Move intel_suspend_gt_powersave() to the end of the GEM suspend sequence. - Add commit message. v4: - Rebased on intel_uncore_forcewake_put(i915->uncore, ...)

2019-11-05drm/i915/cmdparser: Add support for backward jumpsJon Bloomfield1-3/+6
To keep things manageable, the pre-gen9 cmdparser does not attempt to track any form of nested BB_START's. This did not prevent usermode from using nested starts, or even chained batches because the cmdparser is not strictly enforced pre gen9. Instead, the existence of a nested BB_START would cause the batch to be emitted in insecure mode, and any privileged capabilities would not be available. For Gen9, the cmdparser becomes mandatory (for BCS at least), and so not providing any form of nested BB_START support becomes overly restrictive. Any such batch will simply not run. We make heavy use of backward jumps in igt, and it is much easier to add support for this restricted subset of nested jumps, than to rewrite the whole of our test suite to avoid them. Add the required logic to support limited backward jumps, to instructions that have already been validated by the parser. Note that it's not sufficient to simply approve any BB_START that jumps backwards in the buffer because this would allow an attacker to embed a rogue instruction sequence within the operand words of a harmless instruction (say LRI) and jump to that. We introduce a bit array to track every instr offset successfully validated, and test the target of BB_START against this. If the target offset hits, it is re-written to the same offset in the shadow buffer and the BB_START cmd is allowed. Note: This patch deliberately ignores checkpatch issues in the cmdtables, in order to match the style of the surrounding code. We'll correct the entire file in one go in a later patch. v2: set dispatch secure late (Mika) v3: rebase (Mika) v4: Clear whitelist on each parse Minor review updates (Chris) v5: Correct backward jump batching v6: fix compilation error due to struct eb shuffle (Mika) Cc: Tony Luck <tony.luck@intel.com> Cc: Dave Airlie <airlied@redhat.com> Cc: Takashi Iwai <tiwai@suse.de> Cc: Tyler Hicks <tyhicks@canonical.com> Signed-off-by: Jon Bloomfield <jon.bloomfield@intel.com> Signed-off-by: Mika Kuoppala <mika.kuoppala@linux.intel.com> Reviewed-by: Chris Wilson <chris.p.wilson@intel.com>
2019-11-05drm/i915: Support ro ppgtt mapped cmdparser shadow buffersJon Bloomfield1-0/+14
For Gen7, the original cmdparser motive was to permit limited use of register read/write instructions in unprivileged BB's. This worked by copying the user supplied bb to a kmd owned bb, and running it in secure mode, from the ggtt, only if the scanner finds no unsafe commands or registers. For Gen8+ we can't use this same technique because running bb's from the ggtt also disables access to ppgtt space. But we also do not actually require 'secure' execution since we are only trying to reduce the available command/register set. Instead we will copy the user buffer to a kmd owned read-only bb in ppgtt, and run in the usual non-secure mode. Note that ro pages are only supported by ppgtt (not ggtt), but luckily that's exactly what we need.

2019-11-05drm/i915: Disable Secure Batches for gen6+Jon Bloomfield1-0/+1
Retroactively stop reporting support for secure batches through the api for gen6+ so that older binaries trigger the fallback path instead. Older binaries use secure batches pre gen6 to access resources that are not available to normal usermode processes. However, all known userspace explicitly checks for HAS_SECURE_BATCHES before relying on the secure batch feature. Since there are no known binaries relying on this for newer gens we can kill secure batches from gen6, via I915_PARAM_HAS_SECURE_BATCHES. v2: rebase (Mika) v3: rebase (Mika) Signed-off-by: Jon Bloomfield <jon.bloomfield@intel.com> Cc: Tony Luck <tony.luck@intel.com> Cc: Dave Airlie <airlied@redhat.com> Cc: Takashi Iwai <tiwai@suse.de> Cc: Tyler Hicks <tyhicks@canonical.com> Signed-off-by: Mika Kuoppala <mika.kuoppala@linux.intel.com> Reviewed-by: Chris Wilson <chris.p.wilson@intel.com>

vgpu ppgtt notification was split into 2 steps, the first step is to update PVINFO's pdp register and then write PVINFO's g2v_notify register with action code to tirgger ppgtt notification to GVT side. currently these steps were not atomic operations due to no any protection, so it is easy to enter race condition state during the MTBF, stress and IGT test to cause GPU hang. the solution is to add a lock to make vgpu ppgtt notication as atomic operation.

If we don't trust the result of the check while a user is doing mmio access then we shouldn't attempt the check anywhere. - i915_modparams.mmio_debug is not save/restored anymore around user access.

2019-08-09drm/i915: Replace global bsd_dispatch_index with random seedChris Wilson1-3/+0
We keep a global seed for the legacy BSD round-robin selector, but in our testing of multiple simultaneous client workloads, a random seed spreads the load more evenly. (As even as an initial round-robin selector can be!) Removing the global is one less variable we have to find a home for! We can simulate multi-client (both same and mixed workloads) using igt/gem_wsim to work out optimal strategies and then compare our simulation with the actual transcoder on multi-engine machines. This fixed round-robin turns out to be one of the worst methods. No user is advised to use this method; the current suggestion is to use a virtual engine for agnostic batches, randomised submission or using the busyness tracking to select the most idle engine at the time of dispatch. At the present time, intel-media is explicit, but libva still seems to use it, with the exception of batches that must execute on vcs0. Oh well.

The oa object manages the oa buffer and must be allocated when the user intends to read performance counter snapshots. This can be achieved by making the oa object part of the stream object which is allocated when a stream is opened by the user. Attributes in the oa object that are gen-specific are moved to the perf object so that they can be initialized on driver load. The split provides a better separation of the objects used in perf implementation of i915 driver so that resources are allocated and initialized only when needed. v2: Fix checkpatch warnings v3: Addressed Lionel's review comment v4: Rebase v5: Fix rebase/merge issue with ratelimit_state_init Signed-off-by: Umesh Nerlige Ramappa <umesh.nerlige.ramappa@intel.com> Reviewed-by: Lionel Landwerlin <lionel.g.landwerlin@intel.com> Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk> Link: https://patchwork.freedesktop.org/patch/msgid/20190806233002.984-1-umesh.nerlige.ramappa@intel.com

2019-08-02drm/i915: Flush the freed object list on file closeChris Wilson1-1/+0
As we increase the number of RCU objects, it becomes easier for us to have several hundred thousand objects in the deferred RCU free queues. An example is gem_ctx_create/files which continually creates active contexts, which are not immediately freed upon close as they are kept alive by outstanding requests. This lack of backpressure allows the context objects to persist until they overwhelm and starve the system. We can increase our backpressure by flushing the freed object queue upon closing the device fd which should then not impact other clients.

2019-07-31drm/i915/tgl: Tigerlake only has global MOCS registersMichel Thierry1-0/+2
Until Icelake, each engine had its own set of 64 MOCS registers. In order to simplify, Tigerlake moves to only 64 Global MOCS registers, which are no longer part of the engine context. Since these registers are now global, they also only need to be initialized once. >From Gen12 onwards, MOCS must specify the target cache (3:2) and LRU management (5:4) fields and cannot be programmed to 'use the value from Private PAT', because these fields are no longer part of the PPAT. Also cacheability control (1:0) field has changed, 00 no longer means 'use controls from page table', but uncacheable (UC). v2 (Lucas): - Move the changes to the fault registers to a separate commit - the old ones overlap with the range used by the new global MOCS (requested by Daniele) v3 (Lucas): - Clarify comment about setting the unused entries to the same value of index 0, that is the invalid entry (requested by Daniele) - Move changes to DONE_REG and ERROR_GEN6 to a separate commit (requested by Daniele) Cc: Daniele Ceraolo Spurio <daniele.ceraolospurio@intel.com> Signed-off-by: Michel Thierry <michel.thierry@intel.com> Signed-off-by: Tvrtko Ursulin <tvrtko.ursulin@intel.com> Signed-off-by: Lucas De Marchi <lucas.demarchi@intel.com> Reviewed-by: Tomasz Lis <tomasz.lis@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20190730180407.5993-5-lucas.demarchi@intel.com
