As we now have a ring->vma available, we can just lookup our i915 pointer from inside the vm, and so not require the unsightly parameter. Signed-off-by:

Since ggtt_offset_bias is now stored in ggtt.pin_bias, it is duplicated inside i915_gem_context, and can instead be accessed directly from ggtt. v3: Added a helper function to retrieve the ggtt.pin_bias from the vma. v4: Moved the helper function to the previous patch in the series. Dropped the bias from intel_ring_pin. This introduces a slight functional change since we are always pinning the ring a bit higher if GuC is present even though we don't really need to. v8: Fixed patch not applying on the most recent upstream.

Removing the pin bias from GuC allows us to not check for GuC every time we pin a context, which fixes the assertion error on unresolved GuC platform default in mock contexts selftest. It also seems that we were using uninitialized WOPCM variables when setting the GuC pin bias. The pin bias has to be set after the WOPCM, but before the call to i915_gem_contexts_init where the first contexts are pinned. v2: This also makes it so that there's no need to set GuC variables from within the WOPCM init function or to move the WOPCM init, while keeping the correct initialization order. Also for mock tests the pin bias is left at 0 and we make sure that the pin bias with GuC will not be smaller than without GuC. v3: Avoid unused i915 in intel_guc_ggtt_offset if debug is disabled. v4: Squash with WOPCM init reordering. Moved the i915_ggtt_pin_bias helper to this patch, and made some functions use it instead of directly dereferencing i915->ggtt. v5: Since we now don't use wopcm.guc.base for the pin bias there's no need to validate it. It also has already been verified in WOPCM init. v6: Deleted the now unnecessarily introduced includes from previous versions. Dropped naming changes from dev_priv to i915 for better patch readability. v7: Changed some comments to make more sense in the context they're in. v8: Moved and renamed the function which now returns the wopcm.guc.size to intel_guc.c:intel_guc_reserved_gtt_size to avoid any possible confusion with the pin_bias in ggtt, which should be used for pinning. Fixed patch not applying or the most recent upstream. Fixes: f7dc0157 ("drm/i915/uc: Fetch GuC/HuC firmwares from guc/huc specific init") Testcase: igt/drv_selftest/mock_contexts #GuC Signed-off-by:

It would appear that the calculated GuC pin bias was larger than it should be, as the GuC address space does NOT contain the "HW contexts RSVD" part of the WOPCM. Thus, the GuC pin bias is simply the GuC WOPCM size. v5: Clarify the diagram to better represent the GuC address space. Since we now don't use guc.base for the pin bias there's no need to validate it. It also has already been verified in WOPCM init. Bspec: 1180 Signed-off-by:

As GEN8_LR_CONTEXT_ALIGN is I915_GTT_MIN_ALIGNMENT is it functionally equivalent to 0, and we will not be able to reduce the min-alignment for the GTT, so passing 0 is and will remain equivalent. Signed-off-by:

Using PAGE_SIZE for virtual offset alignment is superfluous as it is equal to the minimum gtt alignment and so equivalent to 0. It is also the wrong value to use as we stopped using physical page constructs for the virtual GTT, i.e. it would be preferrable to use I915_GTT_PAGE_SIZE and in these cases merely imply I915_GTT_MIN_ALIGNMENT.

On older HW, gen2/3, fence registers are used for detiling GPU commands and as such changing those registers requires serialisation with the requests on the GPU. Anything running on the GPU is subject to a hang, and so we must be able to recover cleanly in the middle of a stuck wait on a fence register. We can simulate using the fence on the GPU simply by marking the fence as active on the request for this vma, the interface being common to all gen, thus broadening the test. Signed-off-by:

To test eviction from a ppgtt, we just want a ppgtt i.e. something other than the Global GTT which is shared and used by the kernel for HW features like fencing and scanout. However, we also need it to pass !i915_is_ggtt() and the simplest way is to emulate a full user context rather than the internal kernel context that is used for the GGTT. Signed-off-by:

If we issue a device level GPU reset on the older gen, it will disable key components of the GMCH and the display engine. The purpose of wedging is to simply prevent further GEM usage without disabling KMS, so we need to be careful when we do issue the reset on wedging. Signed-off-by:

If we fail during GEM initialisation, we scrub the HW state by performing a device level GPU resuet. However, we want to leave the system in a usable state (with functioning KMS but no GEM) so after scrubbing the HW state, we need to restore some sane defaults and re-enable the low-level common parts of the GPU (such as the GMCH). v2: Restore GTT entries.

The short pulse handler checks if channel equalization is okay and goes onto retrain a link if there are active MST links. This retraining path is not meant for new MST connections, but due to a bug elsewhere, if active_mst_links is < 0 the boolean check for active_mst_links passes and we proceed to retrain a new link. This results in a sequence of failed link training attempts, most likely due to the hardware not setup for link training at that point i.e., missing the DDI pre_enable sequence.

However, we do see the errors being reported and failed reads returning spurious results.

A reasonably common operation is to pin the map of the vma alongside the vma itself for the lifetime of the vma, and so release both pins at the same time as destroying the vma. It is common enough to pull into the release function, making that central function more attractive to a couple of other callsites. The continual ulterior motive is to sweep over errors on module load aborting... Testcase: igt/drv_module_reload/basic-reload-inject Signed-off-by:

Limit the link training clock recovery loop to 10 attempts at LANEx_CR_DONE per DP 1.4 spec section 3.5.1.2.2 and 80 attempts for pre-DP 1.4 (4 voltage levels x 4 preemphasis levels x x 5 identical voltages tries). Some faulty USB-C MST hubs can cause us to get stuck in this loop indefinitely requesting something like: voltage swing: 0, pre-emphasis level: 2 voltage swing: 1, pre-emphasis level: 2 voltage swing: 0, pre-emphasis level: 3 over and over so max_vswing would never be reached, drm_dp_clock_recovery_ok() would never return true and voltage_tries would always get reset to 1.

Not all chipsets have an internal buffer delaying the visibility of writes via the GGTT being visible by other physical paths, but we use a very heavy workaround for all. We only need to apply that workarounds to the chipsets we know suffer from the delay and the resulting coherency issue. Similarly, the same inconsistent coherency fouls up our ABI promise that a write into a mmap_gtt is immediately visible to others. Since the HW has made that a lie, let userspace know when that contract is broken. (Not that userspace would want to use mmap_gtt on those chipsets for other performance reasons...)

Another step in the drv_module_reload fault-injection saga, is that we try to disable the guc twice. Probably. It's a little unclear exactly what is going on in the unload sequence that catches us out, so for the time being suppress the assertion to get the test re-enabled.
