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).

2019-10-31drm/i915/lmem: add the fake lmem regionMatthew Auld1-0/+15
Intended for upstream testing so that we can still exercise the LMEM plumbing and !i915_ggtt_has_aperture paths. Smoke tested on Skull Canyon device. This works by allocating an intel_memory_region for a reserved portion of system memory, which we treat like LMEM. For the LMEMBAR we steal the aperture and 1:1 it map to the stolen region. To enable simply set the i915 modparam fake_lmem_start= on the kernel cmdline with the start of reserved region(see memmap=). The size of the region we can use is determined by the size of the mappable aperture, so the size of reserved region should be >= mappable_end. For now we only enable for the selftests. Depends on CONFIG_DRM_I915_UNSTABLE being enabled. eg. memmap=2G$16G i915.fake_lmem_start=0x400000000 v2: make fake_lmem_start an i915 modparam Signed-off-by: Matthew Auld <matthew.auld@intel.com> Cc: Joonas Lahtinen <joonas.lahtinen@linux.intel.com> Cc: Abdiel Janulgue <abdiel.janulgue@linux.intel.com> Cc: Arkadiusz Hiler <arkadiusz.hiler@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/20191030173320.8850-1-matthew.auld@intel.com

2019-10-18drm/i915: Restore full symmetry in i915_driver_modeset_probe/removeJanusz Krzysztofik1-0/+2
Commit 2d6f6f359fd8 ("drm/i915: add i915_driver_modeset_remove()") claimed removal of asymmetry in probe() and remove() calls, however, it didn't take care of calling intel_irq_uninstall() on driver remove. That doesn't hurt as long as we still call it from intel_modeset_driver_remove() but in order to have full symmetry we should call it again from i915_driver_modeset_remove(). Note that it's safe to call intel_irq_uninstall() twice thanks to commit b318b82455bd ("drm/i915: Nuke drm_driver irq vfuncs"). We may only want to mention the case we are adding in a related FIXME comment provided by that commit. While being at it, update the name of function mentioned as calling it out of sequence as that name has been changed meanwhile by commit 78dae1ac35dd ("drm/i915: Propagate "_remove" function name suffix down").

2019-10-04drm/i915: Pull i915_vma_pin under the vm->mutexChris Wilson1-2/+0
Replace the struct_mutex requirement for pinning the i915_vma with the local vm->mutex instead. Note that the vm->mutex is tainted by the shrinker (we require unbinding from inside fs-reclaim) and so we cannot allocate while holding that mutex. Instead we have to preallocate workers to do allocate and apply the PTE updates after we have we reserved their slot in the drm_mm (using fences to order the PTE writes with the GPU work and with later unbind). In adding the asynchronous vma binding, one subtle requirement is to avoid coupling the binding fence into the backing object->resv. That is the asynchronous binding only applies to the vma timeline itself and not to the pages as that is a more global timeline (the binding of one vma does not need to be ordered with another vma, nor does the implicit GEM fencing depend on a vma, only on writes to the backing store). Keeping the vma binding distinct from the backing store timelines is verified by a number of async gem_exec_fence and gem_exec_schedule tests. The way we do this is quite simple, we keep the fence for the vma binding separate and only wait on it as required, and never add it to the obj->resv itself. Another consequence in reducing the locking around the vma is the destruction of the vma is no longer globally serialised by struct_mutex. A natural solution would be to add a kref to i915_vma, but that requires decoupling the reference cycles, possibly by introducing a new i915_mm_pages object that is own by both obj->mm and vma->pages. However, we have not taken that route due to the overshadowing lmem/ttm discussions, and instead play a series of complicated games with trylocks to (hopefully) ensure that only one destruction path is called! v2: Add some commentary, and some helpers to reduce patch churn.

2019-09-16drm/i915: introduce INTEL_DISPLAY_ENABLED()Jani Nikula1-4/+4
Prepare for making a distinction between not having display and having disabled display. Add INTEL_DISPLAY_ENABLED() and use it where HAS_DISPLAY() is used after intel_device_info_runtime_init(). This is initially duplication, as disabling display still leads to ->pipe_mask = 0 and HAS_DISPLAY() being false. Note that ever since i915.display_disable was introduced, it has not affected PCH detection even if it uses HAS_DISPLAY(), as display disable happens after that. Since INTEL_DISPLAY_ENABLED() will not make sense unless HAS_DISPLAY() is true, include a warning for catching misuses making decisions on INTEL_DISPLAY_ENABLED() when HAS_DISPLAY() is false. v2: Remove INTEL_DISPLAY_ENABLED() check from intel_detect_pch() (Chris) Cc: Chris Wilson <chris@chris-wilson.co.uk> Cc: José Roberto de Souza <jose.souza@intel.com> Cc: Ville Syrjälä <ville.syrjala@linux.intel.com> Reviewed-by: José Roberto de Souza <jose.souza@intel.com> Acked-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Signed-off-by: Jani Nikula <jani.nikula@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20190913100407.30991-1-jani.nikula@intel.com

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>

This removes the last direct dependency of i915_drv.h on i915_reg.h (apart from the i915_reg_t definition). v2: drop unneeded diff, keep the vlv prefix, call functions unconditionally (Jani), fwd declaration of the struct (Chris) Signed-off-by: Daniele Ceraolo Spurio <daniele.ceraolospurio@intel.com> Cc: Imre Deak <imre.deak@intel.com> Cc: Jani Nikula <jani.nikula@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/20190820020147.5667-1-daniele.ceraolospurio@intel.com
2019-08-15drm/i915: Convert a few more bland dmesg info to be device specificChris Wilson1-1/+2
Looking around the GT initialisation, we have a few log messages we think are interesting enough present to the user (such as the amount of L4 cache) and a few to inform them of the result of actions or conflicting HW restrictions (i.e. quirks). These are device specific messages, so use the dev family of printk. v2: shave off a few bytes of .rodata!

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
2019-08-09drm/i915: extract i915_memcpy.h from i915_drv.hJani Nikula1-0/+1
It used to be handy that we only had a couple of headers, but over time i915_drv.h has become unwieldy. Extract declarations to a separate header file corresponding to the implementation module, clarifying the modularity of the driver. Ensure the new header is self-contained, and do so with minimal further includes, using forward declarations as needed. Include the new header only where needed, and sort the modified include directives while at it and as needed. No functional changes.
