Simplify intel_virt_detect_pch() by making it return a PCH id rather than returning the PCH type and setting PCH id for some PCHs. Map the PCH id to PCH type using the shared routine.

This code is similar enough to the CNL code that I considered just adding ICL support to the CNL function, but I think it's still different enough, and having a function specific to ICL allows us to more easily adapt code in case the spec changes more later. We're still missing the power wells and the mbus code, so leave those pieces with a FIXME comment while they're not here yet. v2: Don't use _PICK, don't WARN_ON(1), don't forget the chicken bits. v3: Use _MMIO_PORT() (Ville).

On ICL we have two sets of registers: one for port A and another for port B. The set of port A registers is the same as the CNL registers. Since the procmon table on ICL is the same we want to reuse the CNL function. To do that we add a port argument and make CNL always call the function passing port A. This way, we'll be able to easily reuse the function on ICL when we add icl_display_core_init(). v2: Don't use _PICK() when you can use a ternary operator. v3: Don't use a ternary operation when you can use _MMIO_PORT (Ville).

On BXT/GLK GEN6_PCODE_READ_RC6VIDS fails with MAILBOX_P24C_CC_ILLEGAL_CMD, so don't try to do the query on these platforms. Do it only on SNB, IVB and HSW, where we use this command anyway for RC6 enabling. Based on my tests the command also succeeds on all LLC platforms, but it's not clear if it's really supported on those (it returns 0 aka 245mv for all RC6 states everywhere except on SNB). BSpec lists the command as supported on SKL+ (see P24C_PCODE_MAILBOX_INTERFACE) but that's clearly incorrect, since on SKL/KBL the same command ID is used for SKL_PCODE_LOAD_HDCP_KEYS. Since the command fails on BXT/GLK, the BSpec command list is also incorrect for those platforms (see P_CR_P24C_PCODE_MAILBOX_INTERFACE_0_2_0_GTTMMADR). I filed a request to update that info in Bspec, but for now let's assume a minimal set of platforms where the command is supported.

If we fail to reset the GPU (i915_reset()), we do one final intel_gpu_reset() attempt as we mark the device wedged. The idea here is even though the GPU has proven unreliable (and so we want to stop using it for the time being), we don't want it spinning away in the background whilst the driver idles so we try to reset it one more time. However, we want to dump the i915_gem_set_wedged() debugging info before we do, so that we can see the accurate state of the GPU when it failed.

FORCEWAKE_ACK is depricated by BSpec at least starting from BDW, referring to the multi-threaded version of it instead. Accessing FORCEWAKE_ACK triggers an unclaimed register access error - at least on GLK - see the Reference: below. The correct registers to use would be FORCEWAKE_MT_ACK on IVB+ and FORCEWAKE_ACK_RENDER_GEN9 on SKL+ like it's done elsewhere in the driver. The forcewake check itself is inconsistent and redundant, since there could be other forcewake requesters besides the kernel (being the multithreaded version of the register) and the kernel's per-domain forcewake counters are shown anyway at the end of the file. So let's just remove the check.

After we assert the reset request (and wait for 20us), when the device has been fully reset it asserts the reset-status bit. Before we stop requesting the reset and allow the device to return to normal, we should wait for the reset to be completed. (Similar to how we wait for the device to return to normal after deasserting the reset request.) v2: Rename i915_reset_completed() probe to not cause as much confusion.

Although the mmio are uncached and so should be flushed on every write, be paranoid and do a mmio read after setting the ring head/tail to be sure they have taken effect before moving on. v2: post tail to be pleasing to the eye Signed-off-by: NChris Wilson <chris@chris-wilson.co.uk> Cc: Mika Kuoppala <mika.kuoppala@linux.intel.com> Cc: Joonas Lahtinen <joonas.lahtinen@linux.intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20180208072800.595-1-chris@chris-wilson.co.ukReviewed-by: NMika Kuoppala <mika.kuoppala@linux.intel.com>

Reduce the window of opportunity for set-wedged being called concurrently with reset (after i915_reset() has performed the i915_gem_unset_wedged()) by moving the set_bit(I915_WEDGED) to before we complete the inflight requests. When i915_reset() is being blocked on a request, such completion may allow it to start and beginning resetting the GPU before i915_gem_set_wedged() has finished (and so before set-wedge will have marked the device as wedged). As such, i915_gem_init_hw() may see a wedged device even from inside i915_reset().

Userspace provides a 64b value for the priority, we need to be careful to preserve the full range before validation to prevent truncation (and letting an illegal value pass).
