Weinan Li authored
For the vGPU workloads, now GVT-g use per vGPU scheduler, the per-ring work_thread only pick workload belongs to the current vGPU. And with time slice based scheduler, it waits all the engines become idle before do vGPU switch. So we can run free dispatch in per-ring work_thread, different ring running in different 'vGPU' won't happen. For the workloads between vGPU and Host, this scheduler_mutex can't block host to dispatch workload into other ring engines. Here remove this mutex since it impacts the performance when applications use more than 1 ring engines in 1 vgpu. ring0 running in vGPU1, ring1 running in Host. Will happen. ring0 running in vGPU1, ring1 running in vGPU2. Won't happen. Signed-off-by:

Commit fabef825 ("drm/i915: Drop struct_mutex around frontbuffer flushes") adds a dependency to ifbdev->vma when flushing the framebufer, but the checks are only against the existence of the ifbdev->fb and not against ifbdev->vma. This leaves a window of opportunity where we may try to operate on the fbdev prior to it being probed (thanks to asynchronous booting).

Mario Kleiner authored
The late 2009, 27 inch Apple iMac10,1 has an internal eDP display and an external Mini- Displayport output, driven by a DCE-3.2, RV730 Radeon Mobility HD-4670. The machine worked fine in a dual-display setup with eDP panel + externally connected HDMI or DVI-D digital display sink, connected via MiniDP to DVI or HDMI adapter. However, booting the machine single-display with only eDP panel results in a completely black display - even backlight powering off, as soon as the radeon modesetting driver loads. This patch fixes the single dispay eDP case by assigning encoders based on dig->linkb, similar to DCE-4+. While this should not be generally necessary (Alex: "...atom on normal boards should be able to handle any mapping."), Apple seems to use some special routing here. One remaining problem not solved by this patch is that an external Minidisplayport->DP sink does still not work on iMac10,1, whereas external DVI and HDMI sinks continue to work. The problem affects at least all tested kernels since Linux 3.13 - didn't test earlier kernels, so backporting to stable probably makes sense. v2: With the original patch from 2016, Alex was worried it will break other DCE3.2 systems. Use dmi_match() to apply this special encoder assignment only for the Apple iMac 10,1 from late 2009.

During the review of Coffee Lake workarounds Mika pointed out that WaDisableKillLogic and GEN9_DISABLE_OCL_OOB_SUPPRESS_LOGIC should be removed from CFL and with that I should carry the rv-b. However when doing the v2 I removed another Workaround that should remain because although not mentioned by spec the history of hangs around it advocates on its favor. On some follow-up patches I continued operating on the wrong workardound, but Ville noticed that, so here is the fix for the current CFL code that is upstream already.

When computing a hash for looking up relocation target handles in an execbuf, we start with a large size for the hashtable and proceed to halve it until the allocation succeeds. The final attempt is with an order of 0 (i.e. a single element). This means that we then pass bits=0 to hash_32() which then computes "hash >> (32 - 0)" to lookup the single element. Right shifting a value by the width of the operand is undefined, so limit the smallest hash table we use to order 1. v2: Keep the retry allocation flag for the final pass Fixes: 4ff4b44c ("drm/i915: Store a direct lookup from object handle to vma") Signed-off-by:

There are still cases on these platforms where an attempt is made to configure the CDCLK while the power domain is off, like when coming back from a suspend. So the workaround below is still needed.

We have pretty clear evidence that MSIs are getting lost on g4x and somehow the interrupt logic doesn't seem to recover from that state even if we try hard to clear the IIR. Disabling IER around the normal IIR clearing in the irq handler isn't sufficient to avoid this, so the problem really seems to be further up the interrupt chain. This should guarantee that there's always an edge if any IIR bits are set after the interrupt handler is done, which should normally guarantee that the CPU interrupt is generated. That approach seems to work perfectly on VLV/CHV, but apparently not on g4x. MSI is documented to be broken on 965gm at least. The chipset spec says MSI is defeatured because interrupts can be delayed or lost, which fits well with what we're seeing on g4x. Previously we've already disabled GMBUS interrupts on g4x because somehow GMBUS manages to raise legacy interrupts even when MSI is enabled. Since there's such widespread MSI breakahge all over in the pre-gen5 land let's just give up on MSI on these platforms. Seqno reporting might be negatively affected by this since the legcy interrupts aren't guaranteed to be ordered with the seqno writes, whereas MSI interrupts may be? But an occasioanlly missed seqno seems like a small price to pay for generally working interrupts. Cc: stable@vger.kernel.org Cc: Diego Viola <diego.viola@gmail.com> Tested-by:
