EHL defines two new MOCS table entries but is otherwise compatible with the ICL MOCS table. These table entries (16 and 17) should still be considered unused for ICL and as such their behavior remains undefined for that platform. Signed-off-by:

While we need to flush the wakeref before parking, we do not need to perform the i915_gem_park() itself underneath the wakeref lock, merely the struct_mutex. If we rearrange the locks, we can avoid the unnecessary tainting. Signed-off-by:

To continue the onslaught of removing the assumption of a global execution ordering, another casualty is the engine->timeline. Without an actual timeline to track, it is overkill and we can replace it with a much less grand plain list. We still need a list of requests inflight, for the simple purpose of finding inflight requests (for retiring, resetting, preemption etc). Signed-off-by:

We no longer track the execution order along the engine and so no longer need to enforce ordering of retire along the engine. Signed-off-by:
-
Chris Wilson authored
We need to keep the context image pinned in memory until after the GPU has finished writing into it. Since it continues to write as we signal the final breadcrumb, we need to keep it pinned until the request after it is complete. Currently we know the order in which requests execute on each engine, and so to remove that presumption we need to identify a request/context-switch we know must occur after our completion. Any request queued after the signal must imply a context switch, for simplicity we use a fresh request from the kernel context. The sequence of operations for keeping the context pinned until saved is: - On context activation, we preallocate a node for each physical engine the context may operate on. This is to avoid allocations during unpinning, which may be from inside FS_RECLAIM context (aka the shrinker) - On context deactivation on retirement of the last active request (which is before we know the context has been saved), we add the preallocated node onto a barrier list on each engine - On engine idling, we emit a switch to kernel context. When this switch completes, we know that all previous contexts must have been saved, and so on retiring this request we can finally unpin all the contexts that were marked as deactivated prior to the switch. We can enhance this in future by flushing all the idle contexts on a regular heartbeat pulse of a switch to kernel context, which will also be used to check for hung engines. v2: intel_context_active_acquire/_release Signed-off-by:

This chicken bit should be set before enabling FBC to avoid screen corruption when the plane size has odd vertical and horizontal dimensions. It is safe to leave the bit set even when FBC is disabled. v2: - The bspec's name for this bit on these platforms ("Spare 14") is pretty meaningless. Let's rename the bit definition to something that more accurately reflects what the bit really does.

All AML parts are either KBL ULX or CFL ULX so there is no point in keeping INTEL_SUBPLATFORM_AML around. As these are the only CFL ULX parts (normal CFL didn't have Y SKUs) so we'll just replace IS_AML_ULX with IS_CFL_ULX (it was already paired with IS_KBL_ULX which accounts for the other half of the AML parts).

On non-ULT HSW the "special" WRPLL reference clock select actually means non-SSC. Take that into account when reading out the WRPLL state. Also the non-SSC reference may be either 24MHz or 135MHz, which we can read out from FUSE_STRAP3. The BDW docs actually say: "also indicates whether the CPU and PCH are in a single package or separate packages", so it may be that this is not actually required and we could just assume 135 MHz (just like the code already did). But it doesn't really hurt to read this out as the HSW docs aren't quite so clear. Signed-off-by:

Our PCH refclk init code currently assumes that the PCH SSC reference can only be used for FDI. That is not true and it can be used by SPLL/WRPLL for eDP SSC or clock bending as well. Before we go reconfiguring it let's make sure no PLL is currently using the PCH SSC reference. For some reason the hw is not particularly upset about losing the clock if we immediately follow up with a modeset. Can't really explain why nothing times out during the crtc disable at least, but that's what the logs say. With fastboot the story is quite different and we lose the entire display if we turn off the PCH SSC reference when it's still being used. Since we totally skip configuring the PCH SSC reference it may not be in the proper state for FDI. Hopefully that won't be a problem in practice. We really should move this code to be part of the modeset seqeuence and properly deal with the potentially conflicting requirements imposed on PLL reference clocks. But that requires actual work. Let's toss in a TODO for that. v2: Pimp the commit message with the fastboot vs. not details Cc: Julius B. <freedesktop@blln.gr> Cc: Johannes Krampf <johannes.krampf@gmail.com> Tested-by:Johannes Krampf <johannes.krampf@gmail.com> Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=108773Signed-off-by:
