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:

I cannot find any evidence what we shouldn't try to set those fields when setting a non-CEA mode on an HDMI sink. So just kill that return. Suggested-by:

Let's use the drivers/video/hmdi.c and drm infoframe helpers to build our infoframes. v2: Simplify the logic to compute the buffer size.

First step in the move to the shared infoframe infrastructure, let's move the different infoframe helpers and the write_infoframe() vfunc to a type (enum hdmi_infoframe_type) and a buffer + len instead of using our struct dip_infoframe. v2: constify the infoframe pointer and don't mix signs (Ville Syrjälä) Signed-off-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.

In order to do this for all VMs, it's convenient to rework the logic a bit. This should have no functional impact. Signed-off-by:

Rather than open-code the teardown of a framebuffer, export the routine from intel_display.c. This then make intel_fbdev symmetric in its use of the common intel_framebuffer routines to initialise and clean up the struct intel_framebuffer.

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:

The code itself is no longer accurate without updating once we have multiple address space since clearing the domains of every object requires scanning the inactive list for all VMs. "This code is dead. Just remove it rather than port it to vma." - Chris Wilson Recommended-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:

Seeing the watermark latency values in dmesg might help sometimes. v2: Use DRM_ERROR() when expected latency values are missing Note: We might hit the DRM_ERROR added in this patch and apparently there's not much we can do about that. But I think it'd be interesting to figure out whether that actually happens in the real world, so I didn't apply a s/DRM_ERROR/DRM_DEBUG_KMS/ bikeshed while applying. Signed-off-by:

Rather than having to read the latency values out every time, just store them in dev_priv.

ILK has a slightly different way to read out the watermark latency values. On ILK the LP0 latenciy values are in fact not stored in any register, and instead we must use fixed values. Signed-off-by:

Hangcheck, and some of the recent reset code for guilty batches need to know which address space the object was in at the time of a hangcheck. This is because we use offsets in the (PP|G)GTT to determine this information, and those offsets can differ depending on which VM they are bound into. Since we still only have 1 VM ever, this code shouldn't yet have any impact. Signed-off-by:

With multiple VMs, the eviction code benefits from being able to blindly put pages without needing to know if there are any entities still holding on to those pages. As such it's preferable to return the -EBUSY before the BUG. Eviction code is the only user for now, but overall it makes sense anyway, IMO. Signed-off-by:

For now, objects will maintain the same cache levels amongst all address spaces. This is to limit the risk of bugs, as playing with cacheability in the different domains can be very error prone. In the future, it may be optimal to allow setting domains per VMA (ie. an object bound into an address space). Signed-off-by:

This represents the first half of hooking up VMs to execbuf. Here we basically pass an address space all around to the different internal functions. It should be much more readable, and have less risk than the second half, which begins switching over to using VMAs instead of an obj,vm. The overall series echoes this style of, "add a VM, then make it smart later" Signed-off-by:

Make it aware of which domain it is bound into GGTT, or PPGTT. While modifying the function, add a global gtt flag to the object description. Global is more interesting than aliasing since aliasing is the default. v2: Access VMA directly for start/size instead of helpers (Daniel) Signed-off-by:

To verbalize it, one can say, "pin an object into the given address space." The semantics of pinning remain the same otherwise. Certain objects will always have to be bound into the global GTT. Therefore, global GTT is a special case, and keep a special interface around for it (i915_gem_obj_ggtt_pin). v2: s/i915_gem_ggtt_pin/i915_gem_obj_ggtt_pin Signed-off-by:

Do to the move active/inactive lists, it no longer makes sense to use them for shrinking, since shrinking isn't VM specific (such a need may also exist, but doesn't yet). What we can do instead is use the global bound list to find all objects which aren't active. Signed-off-by:
