There are current places in the code, and there will be more in the future, which iterate the forcewake domains to find out which ones are currently active. To save them from doing this iteration, we can cheaply keep a mask of active domains in dev_priv->uncore.fw_domains_active. This has no cost in terms of object size, even manages to shrink it overall by 368 bytes on my config.

The plan is to introduce intel_has_sagv() and then use it to discover which platforms actually support it. I thought about keeping the functions with their current skl names, but found two problems: (i) skl_has_sagv() would become a very confusing name, and (ii) intel_atomic_commit_tail() doesn't seem to be calling any functions whose name start with a platform name, so the "intel_" naming scheme seems make more sense than the "firstplatorm_" naming scheme here.

Ever since I started working on FBC I was already aware that FBC can really amplify the FIFO underrun symptoms. On systems where FIFO underruns were harmless error messages, enabling FBC would cause the underruns to give black screens. We recently tried to enable FBC on Haswell and got reports of a system that would hang after some hours of uptime, and the first bad commit was the one that enabled FBC. We also observed that this system had FIFO underrun error messages on its dmesg. Although we don't have any evidence that fixing the underruns would solve the bug and make FBC work properly on this machine, IMHO it's better if we minimize the amount of possible problems by just giving up FBC whenever we detect an underrun. v2: New version, different implementation and commit message. v3: Clarify the fact that we run from an IRQ handler (Chris). v4: Also add the underrun_detected check at can_choose() to avoid misleading dmesg messages (DK). v5: Fix Engrish, use READ_ONCE on the unlocked read (Chris).

DP MST provides the capability to send multiple video and audio streams through a single port. This requires the API's between i915 and audio drivers to distinguish between multiple audio capable displays that can be connected to a port. Currently only the port identity is shared in the APIs. This patch adds support for MST with an additional parameter 'int pipe'. The existing parameter 'port' does not change it's meaning. pipe = MST : display pipe that the stream originates from Non-MST : -1 Affected APIs: struct i915_audio_component_ops - int (*sync_audio_rate)(struct device *, int port, int rate); + int (*sync_audio_rate)(struct device *, int port, int pipe, + int rate); - int (*get_eld)(struct device *, int port, bool *enabled, - unsigned char *buf, int max_bytes); + int (*get_eld)(struct device *, int port, int pipe, + bool *enabled, unsigned char *buf, int max_bytes); struct i915_audio_component_audio_ops - void (*pin_eld_notify)(void *audio_ptr, int port); + void (*pin_eld_notify)(void *audio_ptr, int port, int pipe); This patch makes dummy changes in the audio drivers (thanks Libin) for build to succeed.

Update reset path in preparation for engine reset which requires identification of incomplete requests and associated context and fixing their state so that engine can resume correctly after reset. The request that caused the hang will be skipped and head is reset to the start of breadcrumb. This allows us to resume from where we left-off. Since this request didn't complete normally we also need to cleanup elsp queue manually. This is vital if we employ nonblocking request submission where we may have a web of dependencies upon the hung request and so advancing the seqno manually is no longer trivial. ABI: gem_reset_stats / DRM_IOCTL_I915_GET_RESET_STATS We change the way we count pending batches. Only the active context involved in the reset is marked as either innocent or guilty, and not mark the entire world as pending. By inspection this only affects igt/gem_reset_stats (which assumes implementation details) and not piglit. ARB_robustness gives this guide on how we expect the user of this interface to behave: * Provide a mechanism for an OpenGL application to learn about graphics resets that affect the context. When a graphics reset occurs, the OpenGL context becomes unusable and the application must create a new context to continue operation. Detecting a graphics reset happens through an inexpensive query. And with regards to the actual meaning of the reset values: Certain events can result in a reset of the GL context. Such a reset causes all context state to be lost. Recovery from such events requires recreation of all objects in the affected context. The current status of the graphics reset state is returned by enum GetGraphicsResetStatusARB(); The symbolic constant returned indicates if the GL context has been in a reset state at any point since the last call to GetGraphicsResetStatusARB. NO_ERROR indicates that the GL context has not been in a reset state since the last call. GUILTY_CONTEXT_RESET_ARB indicates that a reset has been detected that is attributable to the current GL context. INNOCENT_CONTEXT_RESET_ARB indicates a reset has been detected that is not attributable to the current GL context. UNKNOWN_CONTEXT_RESET_ARB indicates a detected graphics reset whose cause is unknown. The language here is explicit in that we must mark up the guilty batch, but is loose enough for us to relax the innocent (i.e. pending) accounting as only the active batches are involved with the reset. In the future, we are looking towards single engine resetting (with minimal locking), where it seems inappropriate to mark the entire world as innocent since the reset occurred on a different engine. Reducing the information available means we only have to encounter the pain once, and also reduces the information leaking from one context to another. v2: Legacy ringbuffer submission required a reset following hibernation, or else we restore stale values to the RING_HEAD and walked over stolen garbage. v3: GuC requires replaying the requests after a reset. v4: Restore engine IRQ after reset (so waiters will be woken!) Rearm hangcheck if resetting with a waiter.

Since we have a cooperative mode now with a direct reset, we can avoid the contention on struct_mutex and instead try then sleep on the I915_RESET_IN_PROGRESS bit. If the mutex is held and that bit is cleared, all is fine. Otherwise, we sleep for a bit and try again. In the worst case we sleep for an extra second waiting for the mutex to be released (no one touching the GPU is allowed the struct_mutex whilst the I915_RESET_IN_PROGRESS bit is set). But when we have a direct reset, this allows us to clean up the reset worker faster. v2: Remember to call wake_up_bit() after changing (for the faster wakeup as promised) Signed-off-by: NChris Wilson <chris@chris-wilson.co.uk> Reviewed-by: NMika Kuoppala <mika.kuoppala@intel.com> Link: http://patchwork.freedesktop.org/patch/msgid/20160909131201.16673-12-chris@chris-wilson.co.uk

If a waiter is holding the struct_mutex, then the reset worker cannot reset the GPU until the waiter returns. We do not want to return -EAGAIN form i915_wait_request as that breaks delicate operations like i915_vma_unbind() which often cannot be restarted easily, and returning -EIO is just as useless (and has in the past proven dangerous). The remaining WARN_ON(i915_wait_request) serve as a valuable reminder that handling errors from an indefinite wait are tricky. We can keep the current semantic that knowing after a reset is complete, so is the request, by performing the reset ourselves if we hold the mutex. uevent emission is still handled by the reset worker, so it may appear slightly out of order with respect to the actual reset (and concurrent use of the device).

In preparation for introducing a per-engine reset, we can first separate the mixing of the reset state from the global reset counter. The loss of atomicity in updating the reset state poses a small problem for handling the waiters. For requests, this is solved by advancing the seqno so that a waiter waking up after the reset knows the request is complete. For pending flips, we still rely on the increment of the global reset epoch (as well as the reset-in-progress flag) to signify when the hardware was reset. The advantage, now that we do not inspect the reset state during reset itself i.e. we no longer emit requests during reset, is that we can use the atomic updates of the state flags to ensure that only one reset worker is active. v2: Mika spotted that I transformed the i915_gem_wait_for_error() wakeup into a waiter wakeup.

We don't have safe 64-bit mmio writes as they are really split into 2x32-bit writes. This tearing is dangerous as the hardware *will* operate on the intermediate value, requiring great care when assigning. (See, for example, i965_write_fence_reg.) As such we don't currently use them and strongly advise not to us them. Go one step further and remove the 64-bit write vfuncs. v2: Add some more details to the comment about why WRITE64 is absent, and why you need to think twice before using READ64.

In an upcoming patch we'll need the actual mask of subslices in addition to their count, so convert the subslice_per_slice field to a mask. Also we can easily calculate subslice_total from the other fields, so instead of storing a cached version of this, add a helper to calculate it. v2: - Use hweight8() on u8 typed vars instead of hweight32().

The data in this struct is provided both by getting the slice/subslice/eu features available on a given platform and the actual runtime state of these same features which depends on the HW's current power saving state. Atm members of this struct are duplicated in sseu_dev_status and intel_device_info. For clarity and code reuse we can share one struct for both of the above purposes. This patch only moves the struct to the header file, the next patch will convert users of intel_device_info to use this struct too. Instead of unsigned int u8 is used now, which is big enough and is used anyway in intel_device_info.
