Just another useful register to inspect following a GPU hang. v2: Remove partial decoding of RING_MODE to userspace, be consistent and use GEN > 2 guards around RING_MODE everywhere. Signed-off-by:

There is no other state pertaining to the completed requests in the hang, other than gleamed through the ringbuffer, so including the expired requests in the list of outstanding requests simply adds noise. Signed-off-by:

It is useful when looking at captured error states to check the recorded BBADDR register (the address of the last batchbuffer instruction loaded) against the expected offset of the batch buffer, and so do a quick check that (a) the capture is true or (b) HEAD hasn't wandered off into the badlands.

Since contexts are not currently shared between userspace processes, we have an exact correspondence between context creator and guilty batch submitter. Therefore we can save some per-batch work by inspecting the context->pid upon error instead. Note that we take the context's creator's pid rather than the file's pid in order to better track fd passed over sockets. Signed-off-by:

This little helper only exists to safely discard the upper unused 32bits of the general 64-bit VMA address - as we know that all Global GTT currently are less than 4GiB in size and so that the upper bits must be zero. In many places, we use a u32 for the global GTT offset and we want to document where we are discarding the full VMA offset. Signed-off-by:

Treat the VMA as the primary struct responsible for tracking bindings into the GPU's VM. That is we want to treat the VMA returned after we pin an object into the VM as the cookie we hold and eventually release when unpinning. Doing so eliminates the ambiguity in pinning the object and then searching for the relevant pin later. v2: Joonas' stylistic nitpicks, a fun rebase. Signed-off-by:

In a few places, we repeat a call to clear a pointer to a vma whilst unpinning and releasing a reference to its owner. Refactor those into a common function. Signed-off-by:

Use the GGTT VMA as the primary cookie for handing ring objects as the most common action upon the ring is mapping and unmapping which act upon the VMA itself. By restructuring the code to work with the ring VMA, we can shrink the code and remove a few cycles from context pinning. v2: Move the flush of the object back to before the first pin. We use the am-I-bound? query to only have to check the flush on the first bind and so avoid stalling on active rings. Lots of little renames and small hoops. Signed-off-by:

Access through the GTT requires the device to be awake. Ideally i915_vma_pin_iomap() is short-lived and the pinning demarcates the access through the iomap. This is not entirely true, we have a mixture of long lived pins that exceed the wakelock (such as legacy ringbuffers) and short lived pin that do live within the wakelock (such as execlist ringbuffers). Signed-off-by:

We know that the only access to the context object is via the GPU, and the only time when it can be out of the GPU domain is when it is swapped out and unbound. Therefore we only need to clflush the object when binding, thus avoiding any potential stall on touching the domain on an active context. Signed-off-by:

When working with contexts, we most frequently want the GGTT VMA for the context state, first and foremost. Since the object is available via the VMA, we need only then store the VMA. v2: Formatting tweaks to debugfs output, restored some comments removed in the next patch Signed-off-by:

Since the guc allocates and pins and object into the GGTT for its usage, it is more natural to use that pinned VMA as our resource cookie. v2: Embrace naming tautology v3: Rewrite comments for guc_allocate_vma() Signed-off-by:

The VMA are unreferenced, they belong to the object and live until they are closed. However, if we want to use the VMA as a cookie and use it to keep the object alive, we want to hold onto a reference to the object for the lifetime of the VMA cookie. To facilitate this, add a couple of simple wrappers for managing the reference count on the object owning the VMA. Signed-off-by:

A simple little macro to clear a pointer and return the old value. This is useful for writing value = *ptr; if (!value) return; *ptr = 0; ... free(value); in a slightly more concise form: value = fetch_and_zero(ptr); if (!value) return; ... free(value); with the idea that this establishes a pattern that may be extended for atomic use (using xchg or cmpxchg) i.e. atomic_fetch_and_zero() and similar to llist.

In many places, we wish to store the VMA in preference to the object itself and so being able to create the persistent VMA is useful. Signed-off-by:

Previously, we would only set the vma->pages pointer for GGTT entries. However, if we always set it, we can use it to prettify some code that may want to access the backing store associated with the VMA (as assigned to the VMA). Signed-off-by:

No longer is knowing how much of the GTT (both mappable aperture and beyond) relevant, and the output clutters the real information - that is how many objects are allocated and bound (and by who) so that we can quickly grasp if there is a leak. v2: Relent, and rename pinned to indicate display only. Since the display objects are semi-static and are of variable size, they are the interesting objects to watch over time for aperture leaking. The other pins are either static (such as the scratch page) or very short lived (such as execbuf) and not part of the precious GGTT. Signed-off-by:

Only those objects pinned to the display have semi-permanent pins of a global nature (other pins are transient within their local vm). Simplify i915_gem_pinned to only show the pertinent information about the pinned objects within the GGTT. v2: i915_gem_gtt_info is still shared with debugfs/i915_gem_gtt, rename i915_gem_pinned to i915_gem_pin_display to better reflect its contents Signed-off-by:

These two files (i915_gem_active, i915_gem_inactive) no longer give pertinent information since active/inactive tracking is per-vm and so we need the information per-vm. They are obsolete so remove them. Signed-off-by:

With execlists, we have context objects everywhere, not just RCS. So store them for post-mortem debugging. This also has a secondary effect of removing one more unsafe list iteration with using preserved state from the hanging request. And now we can cross-reference the request's context state with that loaded by the GPU. Signed-off-by:

Chris Wilson authored
When capturing the error state, we do not need to know about every address space - just those that are related to the error. We know which context is active at the time, therefore we know which VM are implicated in the error. We can then restrict the VM which we report to the relevant subset. v2: s/i/count_active/ (and similar) Rewrite label generation for "Buffers" Signed-off-by: -
