We have a few modparams which get conditionally exposed based on a Kconfig options and in most cases this also means portions of the driver implementing the respective feature are also left out. Align the visibility of device level and global modparams to make them consistent in this respect. v2: * Fix misplaced parentheses. Signed-off-by:

The different submission backends each have their own preferred behaviour and interrupt setup. Let each handle their own interrupts. This becomes more useful later as we to extract the use of auxiliary state in the interrupt handler that is backend specific. Signed-off-by:

Since we setup the submission method for the engines once, it is easy to assign an enum and use that instead of probing into the backends. Signed-off-by:

Chris Wilson authored
Now that we no longer switch back and forth between guc and execlists, we no longer need to restore the backend's vfunc and can leave them set after initialisation. The only catch is that we lose the submission on wedging and still need to reset the submit_request vfunc on unwedging. Signed-off-by:

When instantiating a tiled object on an L-shaped memory machine, we mark the object as unshrinkable to prevent the shrinker from trying to swap out the pages. We have to do this as we do not know the swizzling on the individual pages, and so the data will be scrambled across swap out/in. Not only do we need to move the object off the shrinker list, we need to mark the object with shrink_pin so that the counter is consistent across calls to madvise. v2: in the madvise ioctl we need to check if the object is currently shrinkable/purgeable, not if the object type supports shrinking Fixes: 0175969e ("drm/i915/gem: Use shrinkable status for unknown swizzle quirks") References: https://gitlab.freedesktop.org/drm/intel/-/issues/3293 References: https://gitlab.freedesktop.org/drm/intel/-/issues/3450Reported-by:

The proper headers have now landed in include/uapi/drm/i915_drm.h, so we can drop i915_gem_lmem.h and instead just reference the real headers for pulling in the kernel doc. Suggested-by:

We generally want to first call i915_gem_object_init_memory_region() before calling into get_pages(), since this sets up various bits of state which might be needed there. Currently for stolen this doesn't matter much, but it might in the future, and at the very least this makes things consistent with the other backends. Signed-off-by:

Commit fb5970da ("drm/i915/gt: Use the kernel_context to measure the breadcrumb size") reordered some operations inside engine_init_common() and added an error unwind path to that function. In that path, a reference to a kernel context candidate supposed to be released on error was put, but the context, pinned when created, was not unpinned first. Fix it by replacing intel_context_put() with destroy_pinned_context() introduced later by commit b436a5f8 ("drm/i915/gt: Track all timelines created using the HWSP"). Signed-off-by:

We use some of the lower bits of the retire function pointer for potential flags, which is quite thorny, since the caller needs to remember to give the function the correct alignment with __i915_active_call, otherwise we might incorrectly unpack the pointer and jump to some garbage address later. Instead of all this let's just pass the flags along as a separate parameter. Suggested-by:

Treat it the same as the fake local-memory stuff, where it is disabled for normal kernels, in case some random UMD is tempted to use this. Once we have all the other bits and pieces in place, like the TTM conversion, we can turn this on for real. Signed-off-by:

All userspace objects must be cleared when allocating the backing store, before they are potentially visible to userspace. For now use simple CPU based clearing to do this for device local-memory objects, note that in the near future this will instead use the blitter engine. Signed-off-by:

For some internal device local-memory objects it would be useful to have an option to CPU clear the pages upon gathering the backing store. Note that this might be before the blitter is useable, which is the case for some internal GuC objects. Signed-off-by:

Same old gem_create but with now with extensions support. This is needed to support various upcoming usecases. v2:(Chris) - Use separate ioctl number for gem_create_ext, instead of hijacking the existing gem_create ioctl, otherwise we run into the issue with being unable to detect if the kernel supports the new extension behaviour. - We now have gem_create_ext.flags, which should be zeroed. - I915_GEM_CREATE_EXT_SETPARAM value is now zero, since this is the index into our array of extensions. - Setup a "vanilla" object which we can directly apply our extensions to. v3:(Daniel & Jason) - drop I915_GEM_CREATE_EXT_SETPARAM. Instead just have each extension do one thing only, instead of generic setparam which can cover various use cases. - add some kernel-doc. Signed-off-by: -

The retire logic uses the 2 lower bits of the pointer to the retire function to store flags. However, the auto_retire function is not guaranteed to be aligned to a multiple of 4, which causes crashes as we jump to the wrong address, for example like this: 2021-04-24T18:03:53.804300Z WARNING kernel: [ 516.876901] invalid opcode: 0000 [#1] PREEMPT SMP NOPTI 2021-04-24T18:03:53.804310Z WARNING kernel: [ 516.876906] CPU: 7 PID: 146 Comm: kworker/u16:6 Tainted: G U 5.4.105-13595-g3cd84167b2df #1 2021-04-24T18:03:53.804311Z WARNING kernel: [ 516.876907] Hardware name: Google Volteer2/Volteer2, BIOS Google_Volteer2.13672.76.0 02/22/2021 2021-04-24T18:03:53.804312Z WARNING kernel: [ 516.876911] Workqueue: events_unbound active_work 2021-04-24T18:03:53.804313Z WARNING kernel: [ 516.876914] RIP: 0010:auto_retire+0x1/0x20 2021-04-24T18:03:53.804314Z WARNING kernel: [ 516.876916] Code: e8 01 f2 ff ff eb 02 31 db 48 89 d8 5b 5d c3 0f 1f 44 00 00 55 48 89 e5 f0 ff 87 c8 00 00 00 0f 88 ab 47 4a 00 31 c0 5d c3 0f <1f> 44 00 00 55 48 89 e5 f0 ff 8f c8 00 00 00 0f 88 9a 47 4a 00 74 2021-04-24T18:03:53.804319Z WARNING kernel: [ 516.876918] RSP: 0018:ffff9b4d809fbe38 EFLAGS: 00010286 2021-04-24T18:03:53.804320Z WARNING kernel: [ 516.876919] RAX: 0000000000000007 RBX: ffff927915079600 RCX: 0000000000000007 2021-04-24T18:03:53.804320Z WARNING kernel: [ 516.876921] RDX: ffff9b4d809fbe40 RSI: 0000000000000286 RDI: ffff927915079600 2021-04-24T18:03:53.804321Z WARNING kernel: [ 516.876922] RBP: ffff9b4d809fbe68 R08: 8080808080808080 R09: fefefefefefefeff 2021-04-24T18:03:53.804321Z WARNING kernel: [ 516.876924] R10: 0000000000000010 R11: ffffffff92e44bd8 R12: ffff9279150796a0 2021-04-24T18:03:53.804322Z WARNING kernel: [ 516.876925] R13: ffff92791c368180 R14: ffff927915079640 R15: 000000001c867605 2021-04-24T18:03:53.804323Z WARNING kernel: [ 516.876926] FS: 0000000000000000(0000) GS:ffff92791ffc0000(0000) knlGS:0000000000000000 2021-04-24T18:03:53.804323Z WARNING kernel: [ 516.876928] CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033 2021-04-24T18:03:53.804324Z WARNING kernel: [ 516.876929] CR2: 0000239514955000 CR3: 00000007f82da001 CR4: 0000000000760ee0 2021-04-24T18:03:53.804325Z WARNING kernel: [ 516.876930] PKRU: 55555554 2021-04-24T18:03:53.804325Z WARNING kernel: [ 516.876931] Call Trace: 2021-04-24T18:03:53.804326Z WARNING kernel: [ 516.876935] __active_retire+0x77/0xcf 2021-04-24T18:03:53.804326Z WARNING kernel: [ 516.876939] process_one_work+0x1da/0x394 2021-04-24T18:03:53.804327Z WARNING kernel: [ 516.876941] worker_thread+0x216/0x375 2021-04-24T18:03:53.804327Z WARNING kernel: [ 516.876944] kthread+0x147/0x156 2021-04-24T18:03:53.804335Z WARNING kernel: [ 516.876946] ? pr_cont_work+0x58/0x58 2021-04-24T18:03:53.804335Z WARNING kernel: [ 516.876948] ? kthread_blkcg+0x2e/0x2e 2021-04-24T18:03:53.804336Z WARNING kernel: [ 516.876950] ret_from_fork+0x1f/0x40 2021-04-24T18:03:53.804336Z WARNING kernel: [ 516.876952] Modules linked in: cdc_mbim cdc_ncm cdc_wdm xt_cgroup rfcomm cmac algif_hash algif_skcipher af_alg xt_MASQUERADE uinput snd_soc_rt5682_sdw snd_soc_rt5682 snd_soc_max98373_sdw snd_soc_max98373 snd_soc_rl6231 regmap_sdw snd_soc_sof_sdw snd_soc_hdac_hdmi snd_soc_dmic snd_hda_codec_hdmi snd_sof_pci snd_sof_intel_hda_common intel_ipu6_psys snd_sof_xtensa_dsp soundwire_intel soundwire_generic_allocation soundwire_cadence snd_sof_intel_hda snd_sof snd_soc_hdac_hda snd_soc_acpi_intel_match snd_soc_acpi snd_hda_ext_core soundwire_bus snd_hda_intel snd_intel_dspcfg snd_hda_codec snd_hwdep snd_hda_core intel_ipu6_isys videobuf2_dma_contig videobuf2_v4l2 videobuf2_common videobuf2_memops mei_hdcp intel_ipu6 ov2740 ov8856 at24 sx9310 dw9768 v4l2_fwnode cros_ec_typec intel_pmc_mux roles acpi_als typec fuse iio_trig_sysfs cros_ec_light_prox cros_ec_lid_angle cros_ec_sensors cros_ec_sensors_core industrialio_triggered_buffer cros_ec_sensors_ring kfifo_buf industrialio cros_ec_sensorhub 2021-04-24T18:03:53.804337Z WARNING kernel: [ 516.876972] cdc_ether usbnet iwlmvm lzo_rle lzo_compress iwl7000_mac80211 iwlwifi zram cfg80211 r8152 mii btusb btrtl btintel btbcm bluetooth ecdh_generic ecc joydev 2021-04-24T18:03:53.804337Z EMERG kernel: [ 516.879169] gsmi: Log Shutdown Reason 0x03 This change fixes this by aligning the function.

In the scenario where local memory is available, we have rely on CPU access via lmem directly instead of aperture. v2: gmch is only relevant for much older hw, therefore we can drop the has_aperture check since it should always be present on such platforms.

We need to generalise our accessor for the page directories and tables from using the simple kmap_atomic to support local memory, and this setup must be done on acquisition of the backing storage prior to entering fence execution contexts. Here we replace the kmap with the object mapping code that for simple single page shmemfs object will return a plain kmap, that is then kept for the lifetime of the page directory. Note that keeping the mapping around is a potential concern here, since while the vma is pinned the mapping remains there for the PDs underneath, or at least until the used_count reaches zero, at which point we can safely destroy the mapping. For 32b this will be even worse since the address space is more limited, but since this change mostly impacts full ppGTT platforms, the justification is that for modern platforms we shouldn't care too much about 32b.

Our code analyzer reported a double free bug. In gen8_preallocate_top_level_pdp, pde and pde->pt.base are allocated via alloc_pd(vm) with one reference. If pin_pt_dma() failed, pde->pt.base is freed by i915_gem_object_put() with a reference dropped. Then free_pd calls free_px() defined in intel_ppgtt.c, which calls i915_gem_object_put() to put pde->pt.base again. As pde->pt.base is protected by refcount, so the second put will not free pde->pt.base actually. But, maybe it is better to remove the first put?

Gen2 tiles are 2KiB in size so i915_gem_object_get_tile_row_size() can in fact return <4KiB, which leads to div-by-zero here. Avoid that. Not sure i915_gem_object_get_tile_row_size() is entirely sane anyway since it doesn't account for the different tile layouts on i8xx/i915... I'm not able to hit this before commit 6846895f ("drm/i915: Replace PIN_NONFAULT with calls to PIN_NOEVICT") and it looks like I also need to run recent version of Mesa. With those in place xonotic trips on this quite easily on my 85x. Cc: stable@vger.kernel.org Reviewed-by:
