Workers on the i915->wq may rearm themselves so for completeness we need to replace our flush_workqueue() with a call to drain_workqueue() before unloading the device. v2: Reinforce the drain_workqueue with an preceding rcu_barrier() as a few of the tasks that need to be drained may first be armed by RCU.

Turns out that just writing CURPOS isn't sufficient to move the cursor on some platforms. My 830 works just fine, but eg. 945 and PNV don't. On those platforms we need to arm even the CURPOS update with a CURBASE write. Even worse, a write to any of the cursor register apart from CURBASE will cancel an already pending cursor update. So if we have armed a CURCNTR/CURBASE update, a subsequent CURPOS write prior to vblank would cancel that armed update. Thus we're left with a cursor that doesn't appear to move, or even change shape. Fix the problem by always performing the CURBASE write after a CURPOS write. Bspec is somewhat unclear which platforms actually require this CURBASE write and which don't. So to keep it simple and to make sure we really fix the problem across all supported devices, let's just perform the CURBASE write unconditionally.

And new fixed_16_16_div wrapper always performs division operation in u64 internally, to avoid any data loss which was happening in earlier version of wrapper. earlier wrapper was converting u32 to fixed16 in 32 bit so we were losing 16-MSB data.

Paulo had noticed that inside cnl_ddi_vswing_program the case was handling voltage but with no indication of type where a missing type could also take us to that path. So my first attempt was to add a message to let clear who trigger that path. However DK had a better idea that is to handle the missed type sooner before it might take to that path. So this v2 here uses his approach. v2: Handle missed type sooner. Cc: Dhinakaran Pandiyan <dhinakaran.pandiyan@intel.com> Cc: Paulo Zanoni <paulo.r.zanoni@intel.com> Signed-off-by:

So far in an attempt to make sure all power wells get disabled during display uninitialization the driver removed any secondary request bits (BIOS, KVMR, DEBUG) that were set for a given power well. The known source for these requests was DMC's request on power well 1 and the misc IO power well. Since DMC is inactive (DC states are disabled) at the point we disable these power wells, there shouldn't be any reason to leave them on. However there are two problems with the above assumption: Bspec requires that the misc IO power well stays enabled (without providing a reason) and there can be KVMR requests that we can't remove anyway (the KVMR request register is R/O). Atm, a KVMR request can trigger a timeout WARN when trying to disable power wells. To make the code aligned to Bspec and to get rid of the KVMR WARN, don't try to remove the secondary requests, only detect them and stop polling for the power well disabled state when any one is set. Also add a comment about the timeout values required by Bspec when enabling power wells and the fact that waiting for them to get disabled is not required by Bspec.

Imre Deak authored
What we want to assert based on the conditions required by Bspec is that power well 2 is disabled, so no need to check for other power wells. In addition we can only check if the driver's request is removed, the actual state depends on whether the other request bits are set or not (BIOS, KVMR, DEBUG). So check only the driver's request bit. Signed-off-by:

Currently, we move all unreferenced contexts to an RCU free list and then onto a worker for eventual reaping. To compensate against this growing into a long list with frequent allocations starving the system of available memory, before we allocate a new context we reap all the stale contexts. This puts all the cost of destroying the context into the next allocator, which is presumably more sensitive to syscall latency and unfair. We can limit the number of contexts being freed by the new allocator to both keep the list trimmed and to allow the allocator to be reasonably fast. Signed-off-by:

Before we create a new context, we try and reap all the stale contexts (i.e. those that are freed but waiting for a worker to come and return their allocations to the system). Before we do this, we retire all requests so that we clear any inflight no longer used contexts (who are only being kept alived by those inflght requests). However, any context that is finally unreferenced by this retirement is put onto an RCU list and not available for immediately reaping, we stall for no immediate benefit. Signed-off-by:

In a IGD passthrough environment, the real ISA bridge may doesn't exist. then pch_id couldn't be correctly gotten from ISA bridge, but pch_id is used to identify LPT_H and LPT_LP. Currently i915 treat all LPT pch as LPT_H,then errors occur when i915 runs on LPT_LP machines with igd passthrough. This patch set pch_id for HSW/BDW according to IGD type and isn't fully correct. But it solves such issue on HSW/BDW ult/ulx machines. QA CI system is blocked by this issue for a long time, it's better that we could merge it to unblock QA CI system. We know the root cause is in device model of virtual passthrough, and will resolve it in the future with several parts cooperation in kernel, qemu and xen.
