Give a name to the plane watermark related data we have currently stored under intel_plane->wm. We also observe that this data is more or less the same that we have in the hsw_pipe_wm_parameters structure, so use it there as well. v2: Make pahole happier Reviewed-by:

There is a bunch of global state that needs to be considered when checking watermarks for validity. Move most of that to a new structure intel_wm_config, to avoid having to pass around so many variables. One notable thing left out is the DDB partitioning information, since we often anyway need to check the same watermarks against both 1/2 and 5/6 DDB partitioning layouts. v2: s/pipes_active/num_pipes_active Reviewed-by:

There are quite a few variables we need to take into account to determine the maximum watermark levels, so it feels a bit cleaner to calculate those rather than just have a bunch of what look like magic numbers. v2: s/pipes_active/num_pipes_active s/othwewise/otherwise Reviewed-by: -

Refactor the code a bit to split the watermark level validity check into a separate function. Also add hack there that allows us to use it even for LP0 watermarks. ATM we don't pre-compute/check the LP0 watermarks, so we just have to clamp them to the maximum and hope things work out. v2: Add some debug prints when we exceed max WM0 Kill pointless ret = false' assignment. Include the check for the already disabled 'result' which got shuffled around when the patchs got reorderd Signed-off-by: -

With the current code there shouldn't be a distinction - however with an upcoming change we intend to allocate a vma much earlier, before it's actually bound anywhere. To do this we have to check node allocation as well for the _bound() check. Signed-off-by:
Ben Widawsky <ben@bwidawsk.net> [danvet: move list_del(&vma->vma_link) from vma_unbind to vma_destroy, again fallout from the loss of "rm/i915: Cleanup more of VMA in destroy".] Signed-off-by:

formerly: "drm/i915: Create VMAs (part 4) - Error capture" Since the active/inactive lists are per VM, we need to modify the error capture code to be aware of this, and also extend it to capture the buffers from all the VMs. For now all the code assumes only 1 VM, but it will become more generic over the next few patches. NOTE: If the number of VMs in a real world system grows significantly we'll have to focus on only capturing the guilty VM, or else it's likely there won't be enough space for error capture. v2: Squashed in the "part 6" which had dependencies on the mm_list change. Since I've moved the mm_list change to an earlier point in the series, we were able to accomplish it here and now. v3: Rebased over new error capture Signed-off-by:

Ben Widawsky authored
formerly: "drm/i915: Create VMAs (part 5) - move mm_list" The mm_list is used for the active/inactive LRUs. Since those LRUs are per address space, the link should be per VMx . Because we'll only ever have 1 VMA before this point, it's not incorrect to defer this change until this point in the patch series, and doing it here makes the change much easier to understand. Shamelessly manipulated out of Daniel: "active/inactive stuff is used by eviction when we run out of address space, so needs to be per-vma and per-address space. Bound/unbound otoh is used by the shrinker which only cares about the amount of memory used and not one bit about in which address space this memory is all used in. Of course to actual kick out an object we need to unbind it from every address space, but for that we have the per-object list of vmas." v2: only bump GGTT LRU in i915_gem_object_set_to_gtt_domain (Chris) v3: Moved earlier in the series v4: Add dropped message from v3 Signed-off-by:

formerly: "drm/i915: Create VMAs (part 3.5) - map and fenceable tracking" The map_and_fenceable tracking is per object. GTT mapping, and fences only apply to global GTT. As such, object operations which are not performed on the global GTT should not effect mappable or fenceable characteristics. Functionally, this commit could very well be squashed in to a previous patch which updated object operations to take a VM argument. This commit is split out because it's a bit tricky (or at least it was for me). Signed-off-by:

We're going to use the 1/2 vs. 5/6 split option already on IVB so the HSW name is not proper. Just give it an intel_ prefix and move it to i915_drv.h so that we can use it there later. Signed-off-by:

We don't need to store the FBC WM enabled status in each watermark level. We anyway have to reduce it down to a single boolean, so just delay checking the FBC WM limit until we're computing the final value. Signed-off-by:

Refactor the watermarks computation for one level to a separate function. This function will now set the ->enable flag to true, even if the watermark level wasn't actually checked yet. In the future we will delay the checking so we must consider all unchecked watermarks as possibly valid. v2: Preserve comment about latency units Signed-off-by:

set_frame() wraps the write_frame() vfunc. Be consistent and name the wrapping function like the vfunc being called. It's doubly confusing as we also have a set_infoframes() vfunc and set_infoframe() doesn't wrap it. Reviewed-by:

From CEA-861: Data Byte 1, bit A0 indicates whether Active Format Data is present in Data Byte 2 bits R3 through R0. A source device shall set A0=1 when any of the AFD bits are set. ie. if we want to set active_aspect, we need to set the active_info_valid bit to 1 as well.

If the user if this API is providing a bigger buffer than the infoframe size, it could be for a could reason. For instance it could be because it gives the buffer that will be written to the hardware, up to the maximum of an infoframe size. Instead of just zeroing up to the infoframe size, let's zero the whole incoming buffer as those extra bytes are also used to compute the ECC and need to be 0. Signed-off-by:

In some places, we want to know if an object is bound in any address space, and not just the global GTT. This often applies when there is a single global resource (object, pages, etc.) function | reason -------------------------------------------------- i915_gem_object_is_inactive | global object i915_gem_object_put_pages | object's pages 915_gem_object_unpin | global object i915_gem_execbuffer_unreserve_object | temporary until we plumb vma pread/pwrite | see the note below Note: set_to_gtt_domain in pwrite/pread is abused as a wait_rendering call - but that once only worked if the object is bound. We really should replace this with a plain wait_rendering call, which would have the upside that in pread it would be clearer that we actually only wait for oustanding gpu writes. Signed-off-by:

Eviction code, like the rest of the converted code needs to be aware of the address space for which it is evicting (or the everything case, all addresses). With the updated bind/unbind interfaces of the last patch, we can now safely move the eviction code over. Signed-off-by:

As alluded to in several patches, and it will be reiterated later... A VMA is an abstraction for a GEM BO bound into an address space. Therefore it stands to reason, that the existing bind, and unbind are the ones which will be the most impacted. This patch implements this, and updates all callers which weren't already updated in the series (because it was too messy). This patch represents the bulk of an earlier, larger patch. I've pulled out a bunch of things by the request of Daniel. The history is preserved for posterity with the email convention of ">" One big change from the original patch aside from a bunch of cropping is I've created an i915_vma_unbind() function. That is because we always have the VMA anyway, and doing an extra lookup is useful. There is a caveat, we retain an i915_gem_object_ggtt_unbind, for the global cases which might not talk in VMAs. > drm/i915: plumb VM into object operations > > This patch was formerly known as: > "drm/i915: Create VMAs (part 3) - plumbing" > > This patch adds a VM argument, bind/unbind, and the object > offset/size/color getters/setters.

These messages are not really useful since it's very easy to check which mode is used for each port: The values programmed are based on the port type, then assigned to the ddi_translations variable. Currently we use DP mode for ports A-D and FDI mode for port E. Also, when we add the code to enable/disable PC8+, intel_prepare_ddi_buffers will be called more often and will eat your dmesg buffers. While at it, fix the coding style of the "for" statement above. Signed-off-by:

Return UINT_MAX for the calculated WM level if the latency is zero. This will lead to marking the WM level as disabled. I'm not sure if latency==0 should mean that we want to disable the level. But that's the implication I got from the fact that we don't even enable the watermark code of the SSKDP register is 0. v2: Use WARN() to scare people Signed-off-by:
