2019-11-12drm/i915: update rawclk also on resumeJani Nikula1-3/+0
Since CNP it's possible for rawclk to have two different values, 19.2 and 24 MHz. If the value indicated by SFUSE_STRAP register is different from the power on default for PCH_RAWCLK_FREQ, we'll end up having a mismatch between the rawclk hardware and software states after suspend/resume. On previous platforms this used to work by accident, because the power on defaults worked just fine. Update the rawclk also on resume. The natural place to do this would be intel_modeset_init_hw(), however VLV/CHV need it done before intel_power_domains_init_hw(). Thus put it there even if it feels slightly out of place. v2: Call intel_update_rawclck() in intel_power_domains_init_hw() for all platforms (Ville).

2019-08-27drm/i915: Call dma_set_max_seg_size() in i915_driver_hw_probe()Lyude Paul1-0/+6
Currently, we don't call dma_set_max_seg_size() for i915 because we intentionally do not limit the segment length that the device supports. However, this results in a warning being emitted if we try to map anything larger than SZ_64K on a kernel with CONFIG_DMA_API_DEBUG_SG enabled: [ 7.751926] DMA-API: i915 0000:00:02.0: mapping sg segment longer than device claims to support [len=98304] [max=65536] [ 7.751934] WARNING: CPU: 5 PID: 474 at kernel/dma/debug.c:1220 debug_dma_map_sg+0x20f/0x340 This was originally brought up on https://bugs.freedesktop.org/show_bug.cgi?id=108517 , and the consensus there was it wasn't really useful to set a limit (and that dma-debug isn't really all that useful for i915 in the first place). Unfortunately though, CONFIG_DMA_API_DEBUG_SG is enabled in the debug configs for various distro kernels. Since a WARN_ON() will disable automatic problem reporting (and cause any CI with said option enabled to start complaining), we really should just fix the problem. Note that as me and Chris Wilson discussed, the other solution for this would be to make DMA-API not make such assumptions when a driver hasn't explicitly set a maximum segment size. But, taking a look at the commit which originally introduced this behavior, commit 78c47830a5cb ("dma-debug: check scatterlist segments"), there is an explicit mention of this assumption and how it applies to devices with no segment size: Conversely, devices which are less limited than the rather conservative defaults, or indeed have no limitations at all (e.g. GPUs with their own internal MMU), should be encouraged to set appropriate dma_parms, as they may get more efficient DMA mapping performance out of it. So unless there's any concerns (I'm open to discussion!), let's just follow suite and call dma_set_max_seg_size() with UINT_MAX as our limit to silence any warnings. Changes since v3: * Drop patch for enabling CONFIG_DMA_API_DEBUG_SG in CI. It looks like just turning it on causes the kernel to spit out bogus WARN_ONs() during some igt tests which would otherwise require teaching igt to disable the various DMA-API debugging options causing this. This is too much work to be worth it, since DMA-API debugging is useless for us. So, we'll just settle with this single patch to squelch WARN_ONs() during driver load for users that have CONFIG_DMA_API_DEBUG_SG turned on for some reason. * Move dma_set_max_seg_size() call into i915_driver_hw_probe() - Chris Wilson Signed-off-by: Lyude Paul <lyude@redhat.com> Reviewed-by: Chris Wilson <chris@chris-wilson.co.uk> Cc: <stable@vger.kernel.org> # v4.18+ Link: https://patchwork.freedesktop.org/patch/msgid/20190823205251.14298-1-lyude@redhat.com (cherry picked from commit acd674af95d3f627062007429b9c195c6b32361d) Signed-off-by: Jani Nikula <jani.nikula@intel.com>

2019-08-09drm/i915: split out uncore_mmio_debugDaniele Ceraolo Spurio1-1/+2
Multiple uncore structures will share the debug infrastructure, so move it to a common place and add extra locking around it. Also, since we now have a separate object, it is cleaner to have dedicated functions working on the object to stop and restart the mmio debug. Apart from the cosmetic changes, this patch introduces 2 functional updates: - All calls to check_for_unclaimed_mmio will now return false when the debug is suspended, not just the ones that are active only when i915_modparams.mmio_debug is set. 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. The value is now never touched by the kernel while debug is disabled so no need for save/restore. v2: squash mmio_debug patches, restrict mmio_debug lock usage (Chris) Signed-off-by: Daniele Ceraolo Spurio <daniele.ceraolospurio@intel.com> Cc: Chris Wilson <chris@chris-wilson.co.uk> Reviewed-by: Chris Wilson <chris@chris-wilson.co.uk> Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk> Link: https://patchwork.freedesktop.org/patch/msgid/20190809063116.7527-1-chris@chris-wilson.co.uk

To maintain a fast lookup from a GT centric irq handler, we want the engine lookup tables on the intel_gt. To avoid having multiple copies of the same multi-dimension lookup table, move the generic user engine lookup into an rbtree (for fast and flexible indexing). v2: Split uabi_instance cf uabi_class v3: Set uabi_class/uabi_instance after collating all engines to provide a stable uabi across parallel unordered construction.

2019-08-02drm/i915: Flush the freed object list on file closeChris Wilson1-0/+3
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.

To help with the encapsulation work done by the following patches, both structures are placed inside a new intel_uc container. Although this results in code with ugly nested dereferences (i915->gt.uc.guc...), it saves us the extra work required in moving the structures twice (i915 -> gt -> uc).
