Some monitors apparently forget to mark any mode as preferred in the EDID. In this particular case we have a very generic looking ID "PNP Model 0 Serial Number 4" / "LVDS 800x600" so a specific quirk doesn't seem particularly wise. Also the quirk we have (EDID_QUIRK_FIRST_DETAILED_PREFERRED) is actually defunct so we'd have to fix it first. When there is no preferred mode we currently fall back to the VBT. That approach fails us here as the VBT mode is 1024x768 whereas the panel resolution is 800x600. So instead of falling back to the VBT when there is no preferred mode let's just pick the first probed mode. Only if the EDID provided no modes we fall back to the VBT. For this machine the VBIOS would appear to select the 800x600 60Hz EST mode rather than the first detailed mode (which is the new fallback will pick). The two modes differ only by having opposite sync polarities, which does not seem to matter to the panel in question. v2: Make sure the probed_modes list is not empty Cc: Adam Jackson <ajax@redhat.com> Cc: Roberto Viola <cagnulein@gmail.com> Tested-by: Roberto Viola <cagnulein@gmail.com> Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=109780Signed-off-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20190321132446.22394-2-ville.syrjala@linux.intel.comReviewed-by: Adam Jackson <ajax@redhat.com> Acked-by: Jani Nikula <jani.nikula@intel.com>

Previously, our view has been always to run the engines independently within a context. (Multiple engines happened before we had contexts and timelines, so they always operated independently and that behaviour persisted into contexts.) However, at the user level the context often represents a single timeline (e.g. GL contexts) and userspace must ensure that the individual engines are serialised to present that ordering to the client (or forgot about this detail entirely and hope no one notices - a fair ploy if the client can only directly control one engine themselves ;) In the next patch, we will want to construct a set of engines that operate as one, that have a single timeline interwoven between them, to present a single virtual engine to the user. (They submit to the virtual engine, then we decide which engine to execute on based.) To that end, we want to be able to create contexts which have a single timeline (fence context) shared between all engines, rather than multiple timelines. v2: Move the specialised timeline ordering to its own function.

Chris Wilson authored
An idea for extending uABI inspired by Vulkan's extension chains. Instead of expanding the data struct for each ioctl every time we need to add a new feature, define an extension chain instead. As we add optional interfaces to control the ioctl, we define a new extension struct that can be linked into the ioctl data only when required by the user. The key advantage being able to ignore large control structs for optional interfaces/extensions, while being able to process them in a consistent manner. In comparison to other extensible ioctls, the key difference is the use of a linked chain of extension structs vs an array of tagged pointers. For example, struct drm_amdgpu_cs_chunk { __u32 chunk_id; __u32 length_dw; __u64 chunk_data; }; struct drm_amdgpu_cs_in { __u32 ctx_id; __u32 bo_list_handle; __u32 num_chunks; __u32 _pad; __u64 chunks; }; allows userspace to pass in array of pointers to extension structs, but must therefore keep constructing that array along side the command stream. In dynamic situations like that, a linked list is preferred and does not similar from extra cache line misses as the extension structs themselves must still be loaded separate to the chunks array. v2: Apply the tail call optimisation directly to nip the worry of stack overflow in the bud. v3: Defend against recursion. v4: Fixup local types to match new uabi Opens: - do we include the result as an out-field in each chain? struct i915_user_extension { __u64 next_extension; __u64 name; __s32 result; __u32 mbz; /* reserved for future use */ }; * Undecided, so provision some room for future expansion.

If we are already in the desired write domain of a set-domain ioctl, then there is nothing for us to do and we can quickly return back to userspace, avoiding any lock contention. By recognising that the write_domain is always a subset of the read_domains, and excluding the no-op case of requiring 0 read_domains in the ioctl, we can infer if the current write_domain matches the target read_domains, there is nothing for us to do. Secondary aspect of this is that we undo the arbitrary fetching and potential flushing of all pages for a set-domain(.write=CPU) call on a fresh object -- which was introduced simply because we do the get-pages before taking the struct_mutex.

When we return pages to the system, we ensure that they are marked as being in the CPU domain since any external access is uncontrolled and we must assume the worst. This means that we need to always flush the pages on acquisition if we need to use them on the GPU, and from the beginning have used set-domain. Set-domain is overkill for the purpose as it is a general synchronisation barrier, but our intent is to only flush the pages being swapped in. If we move that flush into the pages acquisition phase, we know then that when we have obj->mm.pages, they are coherent with the GPU and need only maintain that status without resorting to heavy handed use of set-domain. The principle knock-on effect for userspace is through mmap-gtt pagefaulting. Our uAPI has always implied that the GTT mmap was async (especially as when any pagefault occurs is unpredicatable to userspace) and so userspace had to apply explicit domain control itself (set-domain). However, swapping is transparent to the kernel, and so on first fault we need to acquire the pages and make them coherent for access through the GTT. Our use of set-domain here leaks into the uABI that the first pagefault was synchronous. This is unintentional and baring a few igt should be unoticed, nevertheless we bump the uABI version for mmap-gtt to reflect the change in behaviour. Another implication of the change is that gem_create() is presumed to create an object that is coherent with the CPU and is in the CPU write domain, so a set-domain(CPU) following a gem_create() would be a minor operation that merely checked whether we could allocate all pages for the object. On applying this change, a set-domain(CPU) causes a clflush as we acquire the pages. This will have a small impact on mesa as we move the clflush here on !llc from execbuf time to create, but that should have minimal performance impact as the same clflush exists but is now done early and because of the clflush issue, userspace recycles bo and so should resist allocating fresh objects. Internally, the presumption that objects are created in the CPU write-domain and remain so through writes to obj->mm.mapping is more prevalent than I expected; but easy enough to catch and apply a manual flush. For the future, we should push the page flush from the central set_pages() into the callers so that we can more finely control when it is applied, but for now doing it one location is easier to validate, at the cost of sometimes flushing when there is no need.

The timeline->name is only used for convenience in pretty printing the i915_request.fence->ops->get_timeline_name() and it is just as convenient to pull it from the gem_context directly.

Switch to bitmap_zalloc() to show clearly what we are allocating. Besides that it returns pointer of bitmap type instead of opaque void *.

skl_update_pipe_wm() is quite pointless now. Just inline it into skl_compute_wm(). v2: s/skl_build_pipe_wm/skl_update_pipe_wm/ in the commit message (Matt) Cc: Neel Desai <neel.desai@intel.com> Signed-off-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20190312205844.6339-10-ville.syrjala@linux.intel.comReviewed-by: Matt Roper <matthew.d.roper@intel.com>

{skl,icl}_build_plane_wm() don't need to be passed the pipe_wm, so don't. And skl_build_pipe_wm() can easily dig it out itself.

Clean up skl_allocate_pipe_ddb() a bit by moving the 'wm' variable to tighter scope. We'll also consitify it where appropriate. Also initialize plane_alloc/uv_plane_alloc when decrlaring them rather than later. v2: Update commit message (Matt) Cc: Neel Desai <neel.desai@intel.com> Signed-off-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20190312205844.6339-8-ville.syrjala@linux.intel.comReviewed-by: Matt Roper <matthew.d.roper@intel.com>

Currently we disable all the watermarks above the selected max level for every plane. That would mean that the cursor's watermarks may also get modified when another plane causes the selected max watermark level to change. That is not so great as we would like to keep the cursor as indepenedent as possible to avoid having to throttle it in resposne to other plane activity. To avoid that let's keep the watermarks enabled even for levels above the max selected watermark level, iff the plane has enough ddb for that particular level. This way the cursor's enabled watermarks only depend on the cursor itself. This is safe because the hardware will never choose to use a watermark level unless all enabled planes have also enabled that level.
