WaDisable4x2SubspanOptimization isn't listed for VLV in the workaround database, but BSpec says that the relevant bit must be set. Add a comment to remind people of this. Signed-off-by:

Call gen7_setup_fixed_func_scheduler() on VLV as well. Signed-off-by:

Ville Syrjälä authored
BSpec states that the thread override values set by gen7_setup_fixed_func_scheduler() are invalid for HSW. So let's not muck around with them. Since gen7_setup_fixed_func_scheduler() now has two totally independent parts, one for IVB and one for HSW, move the HSW part directly into haswell_init_clock_gating(). Note tht there's another workaround by the name of WaHSWVSRefCountFullforceMissDisable which basically claims that later steppings don't need the fix, but since WaVSRefCountFullforceMissDisable is listed to be needed for all steppings play it safe and keep applying the workaround.

The current comments indicate that this function implements WaVSRefCountFullforceMissDisable, which is only true for HSW. The original purpose of the function is to implement WaVSThreadDispatchOverride (and a bit more). Fix up the comments to match reality. Signed-off-by:

Someone copy pasted the comment from the SNB code w/o reading it. We never actually implemented the workaround to disable RCPB unit clock gating on IVB. It would have been needed for early steppings, but we don't care about those anymore, so just remove the stale comment. Signed-off-by:

There are cases where we want to know if there is a full, or aliased PPGTT. Currently, in fact the only distinction we ever need to make is when we're using full PPGTT. This patch is simply to promote readability and clarify for the confusing existing usage where "aliasing" meant aliasing and full. v2: Remove USES_ALIASING_PPGTT since there are currently no cases where we need to check if we're using aliasing, but not full PPGTT.

Having to use i915.i915_foo is inconsistent and a bit on the verbose side. Drop the prefix per Daniel's request, who also says this is not ABI we need to maintain. Signed-off-by:

At least I couldn't find it in the Haswell Bspec any more and we've tried to test-boot a Haswell machine with num_pipes forced to 0 (i.e. hit the PCH_NOP path) and the unclaimed register logic complained. So restrict this dance to just ivb platforms. v2: Art pointed out that the bits simply moved on hsw+ v3: Buy code terseneness with a notch of sublety as suggested by Chris. v4: Frob the right bit, spotted by Art.

A lot of the WM functions are only reading from that structure and are already using const. While converting the code to use dev_priv instead of dev, I noticed a few places where we can give that hint. Signed-off-by:

With 20+ module parameters, I think referring to them via a struct improves clarity over just having a bunch of globals. While at it, move the parameter initialization and definitions into a new file i915_params.c to reduce clutter in i915_drv.c. Apart from the ill-named i915_enable_rc6, i915_enable_fbc and i915_enable_ppgtt parameters, for which we lose the "i915_" prefix internally, the module parameters now look the same both on the kernel command line and in code. For example, "i915.modeset". The downsides of the change are losing static on a couple of variables and not having the initialization and module_param_named() right next to each other. On the other hand, all module parameters are now defined in one place at i915_params.c. Plus you can do this to find all module parameter references: $ git grep "i915\." -- drivers/gpu/drm/i915 v2: - move the definitions into a new file - s/i915_params/i915/ - make i915_try_reset i915.reset, for consistency Signed-off-by:

WaMiSetContext_Hang tells us that a MI_NOOP must follow MI_SET_CONTEXT. The other thing WaMiSetContext_Hang seems to say is that URB_FENCE isn't allowed to straddle two cachelines. But we don't issue those from the kernel so we don't care. Signed-off-by:

Many times in the past we have concluded that the cause of the GPU hang has been that the hw status page was stale, usually because the GPU and CPU disagreed over the address of the page. Having stumbled across yet another issue that seems to be related to the HWSP, it is time to include that information in the GPU error dump. Signed-off-by:

Through a twisty and circuituous path it is possible to currently trick the code into creating a default context and forgetting to pin it immediately into the GGTT. (This requires a system using contexts without an aliasing ppgtt, which is currently restricted to Baytrails machines manually specifying a module parameter to force enable contexts, or on Sandybridge and later that manually disable the aliasing ppgtt.) The consequence is that during module unload we attempt to unpin the default context twice and encounter a BUG remonstrating that we attempt to unpin an unbound object.

Having a 4 byte register at 0x321b seems unlikely as that's not 4 byte aligned. Since later platforms have more or less the same FBC registers with new names, assume that FBC_FENCE_OFF is at 0x3218 just like DPFC_FENCE_YOFF. This feels like a simple typo in BSpec. 321Bh looks a lot like 3218h after all. Should still be tested on real hardware of course. But I don't have any mobile gen4 systems. Signed-off-by:
