2019-05-21drm/vmwgfx: Use the dma scatter-gather iterator to get dma addressesThomas Hellstrom2-21/+8
Use struct sg_dma_page_iter in favour struct of sg_page_iter, which fairly recently was declared useless for obtaining dma addresses. With a struct sg_dma_page_iter we can't call sg_page_iter_page() so when the page is needed, use the same page lookup mechanism as for the non-sg dma modes instead of calling sg_dma_page_iter. Note, the fixes tag doesn't really point to a commit introducing a failure / regression, but rather to a commit that implemented a simple workaround for this problem.

2019-05-21drm/i915/gvt: use cmd to restore in-context mmios to hw for gen9 platformYan Zhao3-15/+13
for restore-inhibit context, hardware will not load in-context mmios (engine context part) to hardware, but hardware will save the mmio values in hardware back to context image. So, in order to save correct values of vGPU back to context image, values of vGPU mmios have to be loaded into hardware first for restore-inhibit context. In this patch, the mechanism is applied to all gen9 platform. The reason excluding gen8 platforms is only because of lacking of testing on those platforms. v3: for mocs registers, goto in-context mmios save-restore path for skl platform as well (weinan li) v2: update vreg when scanning indirect context for inhibit context for gen9 Cc: Weinan Li <weinan.z.li@intel.com> Acked-by: Weinan Li <weinan.z.li@intel.com> Signed-off-by: Yan Zhao <yan.y.zhao@intel.com> Signed-off-by: Zhenyu Wang <zhenyuw@linux.intel.com>

"To track whether a request has started on HW, we can emit a breadcrumb at the beginning of the request and check its timeline's HWSP to see if the breadcrumb has advanced past the start of this request." It means all the request which timeline's has_init_breadcrumb is true, then the emit_init_breadcrumb process must have before emitting the real commands, otherwise, the scheduler might get a wrong state of this request during reset. If the request is exactly the guilty one, the scheduler won't terminate it with the wrong state. To avoid this, do emit_init_breadcrumb for all the requests from gvt. v2: cc to stable kernel Fixes: 8547444137ec ("drm/i915: Identify active requests") Cc: stable@vger.kernel.org Acked-by: Zhenyu Wang <zhenyuw@linux.intel.com> Signed-off-by: Weinan <weinan.z.li@intel.com> Signed-off-by: Zhenyu Wang <zhenyuw@linux.intel.com>

2019-05-20drm/i915: Truly bump ready tasks ahead of busywaitsChris Wilson1-19/+12
In commit b7404c7ecb38 ("drm/i915: Bump ready tasks ahead of busywaits"), I tried cutting a corner in order to not install a signal for each of our dependencies, and only listened to requests on which we were intending to busywait. The compromise that was made was that instead of then being able to promote the request with a full NOSEMAPHORE like its non-busywaiting brethren, as we had not ensured we had cleared the semaphore chain, we settled for only using the NEWCLIENT boost. With an over saturated system with multiple NEWCLIENTS in flight at any time, this was found to be an inadequate promotion and left us with a much poorer scheduling order than prior to using semaphores. The outcome of this patch, is that all requests have NOSEMAPHORE priority when they have no dependencies and are ready to run and not busywait, restoring the pre-semaphore ordering on saturated systems. We can demonstrate the effect of poor scheduling order by oversaturating the system using gem_wsim on a system with multiple vcs engines (i.e running the same workloads across more clients than required for peak throughput, e.g. media_load_balance_17i7.wsim -c4 -b context): x v5.1 (normalized) + tip * fix +------------------------------------------------------------------------+ | x | | x | | x | | x | | %x | | %%x | | %%x | | %%x | | %%x | | %%x | | %%x | | %%x | | %%x | | %%x | | %%x | | %#x | | %#x | | %#x | | %#x | | %#x | | + %#xx | | + %#xx | | + %%#xx | | + %%#xx | | + %%#xx | | + %%#xx | | + %%##x | | +++ %%##x | | +++ %%##x | | +++ %%##x | | ++++ %%##x | | ++++ %%##x | | ++++ %%##xx | | ++++ %###xx | | ++++ %###xx | | ++++ %###xx | | ++++ %###xx | | ++++ + %#O#xx | | ++++ + %#O#xx | | ++++++ + %#O#xx | | ++++++++++ %OOOxxx| | ++++++++++ + %#OOO#xx| | + ++++++++++++ ++ +++++ + ++ @@OOOO#xx| | |A_| | ||__________M_______A____________________| | | |A_| | +------------------------------------------------------------------------+ N Min Max Median Avg Stddev x 120 0.99456 1.00628 0.999985 1.0001545 0.0024387139 + 120 0.873021 1.00037 0.884134 0.90148752 0.039190862 Difference at 99.5% confidence -0.098667 +/- 0.0110762 -9.86517% +/- 1.10745% (Student's t, pooled s = 0.0277657) % 120 0.990207 1.00165 0.9970265 0.99699748 0.0021024 Difference at 99.5% confidence -0.003157 +/- 0.000908245 -0.315651% +/- 0.0908105% (Student's t, pooled s = 0.00227678) Fixes: b7404c7ecb38 ("drm/i915: Bump ready tasks ahead of busywaits") Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk> Cc: Tvrtko Ursulin <tvrtko.ursulin@intel.com> Cc: Dmitry Rogozhkin <dmitry.v.rogozhkin@intel.com> Cc: Dmitry Ermilov <dmitry.ermilov@intel.com> Reviewed-by: Tvrtko Ursulin <tvrtko.ursulin@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20190515130052.4475-2-chris@chris-wilson.co.uk (cherry picked from commit 17db337f5098d29415314c4a588b842fc684394b) Signed-off-by: Joonas Lahtinen <joonas.lahtinen@linux.intel.com>
2019-05-20drm/i915: Downgrade NEWCLIENT to non-preemptiveChris Wilson3-5/+4
Commit 1413b2bc0717 ("drm/i915: Trim NEWCLIENT boosting") had the intended consequence of not allowing a sequence of work that merely crossed into a new engine the privilege to be promoted to NEWCLIENT status. It also had the unintended consequence of actually making NEWCLIENT effective on heavily oversubscribed transcode machines and impacting upon their throughput. If we consider a client packet composed of (rcsA, rcsB, vcs) and 30 of those clients, using the NEWCLIENT boost that will be scheduled as rcsA x 30, (rcsB, vcs) x 30 where as before it would have been (rcsA, rcsB, vcs) x 30 That is with NEWCLIENT only boosting the first request of each client, we would execute all rcsA requests prior to running on the vcs engines; acruing a lot of dead time as compared to the previous case where the vcs engine would be started in parallel to processing the second client. The previous patch has the effect of delaying submission until it is required by a third party (either the user with an explicit wait, or by another client/engine). We reduce the NEWCLIENT bump to a mere WAIT, which has the effect of removing its preemptive grant and reducing it to the same level as any other user interaction -- that it will not be promoted above the interengine dependencies, and so preventing NEWCLIENTS from starving other engines. This a large nerf to the rrul properties of the current NEWCLIENT, but it still does give prioritised submission to new requests from light workloads.

2019-05-20drm/i915: Bump signaler priority on adding a waiterChris Wilson4-14/+21
The handling of the no-preemption priority level imposes the restriction that we need to maintain the implied ordering even though preemption is disabled. Otherwise we may end up with an AB-BA deadlock across multiple engine due to a real preemption event reordering the no-preemption WAITs. To resolve this issue we currently promote all requests to WAIT on unsubmission, however this interferes with the timeslicing requirement that we do not apply any implicit promotion that will defeat the round-robin timeslice list. (If we automatically promote the active request it will go back to the head of the queue and not the tail!) So we need implicit promotion to prevent reordering around semaphores where we are not allowed to preempt, and we must avoid implicit promotion on unsubmission. So instead of at unsubmit, if we apply that implicit promotion on adding the dependency, we avoid the semaphore deadlock and we also reduce the gains made by the promotion for user space waiting. Furthermore, by keeping the earlier dependencies at a higher level, we reduce the search space for timeslicing without altering runtime scheduling too badly (no dependencies at all will be assigned a higher priority for rrul). v2: Limit the bump to external edges (as originally intended) i.e. between contexts and out to the user.
