Our reset handling has a retry layer further up in the chain. As we have told the engine to prepare for reset, and failed it, make sure to remove that preparation so that the next attempted reset has a clean slate by triggering another full prepare cycle for the engines. v2: ret as int, simplified cleanup (Chris) Cc: Chris Wilson <chris@chris-wilson.co.uk> Signed-off-by:

To allow for future non-object backed vma, we need to be able to specialise the callbacks for binding, et al, the vma. For example, instead of calling vma->vm->bind_vma(), we now call vma->ops->bind_vma(). This gives us the opportunity to later override the operation for a custom vma. v2: flip order of unbind/bind Signed-off-by:

Chris Wilson authored
In order to allow ourselves to use VMA to wrap other entities other than GEM objects, we need to allow for the vma->obj backpointer to be NULL. In most cases, we know we are operating on a GEM object and its vma, but we need the core code (such as i915_vma_pin/insert/bind/unbind) to work regardless of the innards. The remaining eyesore here is vma->obj->cache_level and related (but less of an issue) vma->obj->gt_ro. With a bit of care we should mirror those on the vma itself. Signed-off-by:

As part of our GEM initialisation now, we send a request to the hardware in order to record the initial GPU state. This coupled with deferred idle workers, makes aborting on error tricky. We already have the mechanism in place to wait on the GPU and cancel all the deferred workers for suspend, so let's reuse it during the error teardown. It is already used in places for later init error handling, but doing so at this point is slightly ugly due to the mutex dance (it's ok, the module load is still single threaded).

When we reach the magic value and do inject a fault into our module load, mark the module option as being hit. Since we fail from inside pci probe, the module load isn't actually aborted and the module (and parameters) are left lingering. igt can then inspect the parameter on its synchronous completion of modprobe to see if the fault injection was successful, and will keeping on injecting new faults until the module succeeds in loading having surpassed the number of fault points. v2: Reset to 0 after being hit; Signed-off-by:

In the near future, I want to subclass gen6_hw_ppgtt as it contains a few specialised members and I wish to add more. To avoid the ugliness of using ppgtt->base.base, rename the i915_hw_ppgtt base member (i915_address_space) as vm, which is our common shorthand for an i915_address_space local. Signed-off-by:

As Chris has discovered on his Ivybridge, and later automated test runs have confirmed, on most of our platforms hrtimer faced with heavy GPU load can occasionally become sufficiently imprecise to affect PMU sampling calculations. This means we cannot assume sampling frequency is what we asked for, but we need to measure the interval ourselves. This patch is similar to Chris' original proposal for per-engine counters, but instead of introducing a new set to work around the problem with frequency sampling, it swaps around the way internal frequency accounting is done. Instead of accumulating current frequency and dividing by sampling frequency on readout, it accumulates frequency scaled by each period. v2: * Typo in commit message, comment on period calculation and USEC_PER_SEC.

One thing we didn't really understand about the OA report is that the ContextID field (dword 2) is copy of the context descriptor (dword 1). On Gen8->10 and without using GuC we didn't notice the issue because we only checked the 21bits of the ContextID field in the OA reports which matches exactly the hw_id stored into the context descriptor. When using GuC submission we have an issue of a non matching hw_id because GuC uses bit 20 of the hw_id to signal proxy submission. This change introduces a mask to compare only the relevant bits. On ICL the context descriptor format has changed and we failed to address this. On top of using a mask we also need to shift the bits properly. v2: Reuse lrc_desc rather than recomputing part of it (Chris/Michel) v3: Always pin the context we're filtering with (Chris) Signed-off-by:

We currently using GuC as a proxy to the hardware. When Guc is used in such mode, it consumes the bit 20 of the hw_id to indicate that the workload was submitted by proxy. So far we probably haven't seen the issue because we need to allocate 1048576+ contexts to hit this issue. Still, we should avoid allocating the hw_id on that bit and restriction to bits [0:19] (i.e 20bits instead of 21). v2: Leave the max hw_id computation in i915_gem_context.c (Michel) v3: Be consistent on if/else usage (Chris) Signed-off-by:

PLLs are the source clocks for the DDIs so in order to determine the ddi clock we need to check the PLL configuration. This gets a little tricky for ICL since there is no register bit that maps directly to the link clock. So this patch creates a separate function in intel_dpll_mgr.c to obtain the write array PLL Params and compares the set pll_params with the table to get the corresponding link clock. v2: - Fix the encoder type check (DK). - Improve our error checking, return a sane value (Mika, Paulo). - Fix table entries (Paulo).

Let's not take any chances by using a shortcut to mark the objects as in the CPU domain upon freezing (all pages will be written to disk and so on restore all objects will start from the CPU domain). Currently, we simply mark the objects as being in the CPU domain, bypassing the flushes. Let's call the full domain transfer function so that we have less special case code (and symmetry with the suspend path) even though it will be mostly redundant. Signed-off-by:

As we have already suspended the device, this should be a no-op except for marking that all writes are indeed complete. The downside is that we then have to walk all the lists of objects for what should be a no-op (in some cases they will be mmio read to ensure the GGTT writes are indeed flushed, and clflushes to ensure that cpu writes are in memory). It seems prudent and the safer course for us to ensure all writes are flushed to memory before suspend. Signed-off-by:
