DDI buffer prorgramming works quite differently depending on the mode of the DDI port (DP/eDP/FDI vs. HDMI/DVI). Let's split the function that does the programming into two matching variants as well. Signed-off-by:

When the DDI port is in HDMI/DVI mode, it automagically uses the buffer translations values from entry 9. Let's make that explicit in the code. Signed-off-by:

Now that the SKL iboost programming is done from intel_ddi_pre_enable() for HDMI, let's move the BXT bxt_ddi_vswing_sequence() call there as well. This makes things look more similar to the DP/eDP case which is handled in ddi_signal_levels(). Cc: Imre Deak <imre.deak@intel.com> Signed-off-by:

Bspec says: "For DDIA with x4 capability (DDI_BUF_CTL DDIA Lane Capability Control = DDIA x4), the I_boost value has to be programmed in both tx_blnclegsctl_0 and tx_blnclegsctl_4." Currently we only program tx_blnclegsctl_0. Let's do the other one as well.

In the middle of intel_gt_init_powersave() we have an if-chain that ends with a universal else clause to read gen6+ registers. Older platforms like Pineview that end up here do not like those registers and may even OOPS whilst reading them! Fixes: 3ea9a80132 ("drm/i915: Perform static RPS frequency setup ...")

It appears that we never told Pineview it has a RENDER_RING. This was all fine until we started using the ring_mask for determining all the available rings to initialise for legacy ringbuffer submission in commit 88d2ba2e ("drm/i915: Unify engine init loop"). Though really it is a latent bug since the ring_mask inception in commit 73ae478c ("drm/i915: Replace has_bsd/blt/vebox with a mask"). To prevent similar mishaps in future, add a WARN_ON() if we find ourselves with a device without any rings.

SNB (and IVB too I suppose) starts to misbehave if the GPU gets stuck in an infinite batch buffer loop. The GPU apparently hogs something critical and CPUs start to lose interrupts and whatnot. We can keep the system limping along by unmasking some interrupts in GEN6_PMINTRMSK. The EI up interrupt has been previously chosen for that task, so let's never mask it. v2: s/gen6_rps_pm_mask/gen6_sanitize_rps_pm_mask/ (Chris) Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=93122Signed-off-by:

Inside the error capture itself, we refer to not only the hardware engine, its ringbuffer but also the capture state.

Bspec tells us to keep bashing the PCU for up to 3ms when trying to inform it about an upcoming change in the cdclk frequency. Currently we only keep at it for 15*10usec (+ whatever delays gets added by the sandybridge_pcode_read() itself). Let's change the limit to 3ms. I decided to keep 10 usec delay per iteration for now, even though the spec doesn't really tell us to do that.

The obj->batch_pool_link is only inspected when traversing the batch pool list and when on the batch pool list the object is referenced. Thus when freeing the batch pool list, we only need to unreference the object and do not have to worry about the obj->batch_pool_link. Signed-off-by:

Upon release of the file (i.e. the user calls close(fd)), we decouple all objects from the client list so that we don't chase the dangling file_priv. As we always inspect file_priv first, we only need to nullify that pointer and can safely ignore the list_head. Signed-off-by:

During the idle-worker we disable the hangcheck and so kick any waiters that should have been completed (since the GPU is now idle). Unlike the hangcheck, we do not take any care to avoid the race between the irq handler and ourselves, and so it is possible for us to declare a missed interrupt even as the bottom-half is being scheduled to run. Let's ignore this race to stop a potential false-positive error. References: https://bugs.freedesktop.org/show_bug.cgi?id=96974Signed-off-by:

The exit path in intel_overlay_put_image_ioctl() first unlocks the struct_mutex, then drops its reference to 'new_bo' by calling i915_gem_object_put(). As it isn't holding the mutex at this point, this should be i915_gem_object_put_unlocked(). This was previously correct but got splatted in the recent s/drm_gem_object_unreference/i915_gem_object_put/ where the _unlocked suffix was lost in this one case. v2: don't bother fixing whitespace glitch [Chris Wilson] Chris can do it next time he touches gem_evict.c ;) Fixes: f8c417cd drm/i915: Rename drm_gem_object_unreference in preparation ...

'ring' is an old deprecated term for a GPU engine, so we're trying to phase out all such terminology. eb_select_ring() not only has 'ring' (meaning engine) in its name, but it has an ugly calling convention whereby it returns an errno and stores a pointer-to-engine indirectly through an output parameter. As there is only one error it ever returns (-EINVAL), we can make it return the pointer directly, and have the caller pass back the error code -EINVAL if the pointer result is NULL. Thus we can replace - ret = eb_select_ring(dev_priv, file, args, &engine); - if (ret) - return ret; with + engine = eb_select_engine(dev_priv, file, args); + if (!engine) + return -EINVAL; for increased clarity and maybe save a few cycles too.

'ring' is an old deprecated term for a GPU engine. Chris Wilson wants to use the name for what is currently known as an intel_ringbuffer, but it will be dreadfully confusing if some rings are ringbuffers but other rings are still engines. So this patch changes the names of a bunch of parameters called 'ring' to either 'engine' or 'engine_id' according to what they actually are. Signed-off-by:

Ringbuffers are now being written to either through LLC or WC paths, so treating them as simply iomem is no longer adequate. However, for the older !llc hardware, the hardware is documentated as treating the TAIL register update as serialising, so we can relax the barriers when filling the rings (but even if it were not, it is still an uncached register write and so serialising anyway.). For simplicity, let's ignore the iomem annotation. v2: Remove iomem from ringbuffer->virtual_address v3: And for good measure add iomem elsewhere to keep sparse happy Signed-off-by:
