2019-03-22drm/i915: Pick the first mode from EDID as the fixed mode when there is no ↵Ville Syrjälä1-3/+18
preferred mode 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 <[email protected]> Cc: Roberto Viola <[email protected]> Tested-by: Roberto Viola <[email protected]> Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=109780 Signed-off-by: Ville Syrjälä <[email protected]> Link: https://patchwork.freedesktop.org/patch/msgid/[email protected] Reviewed-by: Adam Jackson <[email protected]> Acked-by: Jani Nikula <[email protected]>

2019-03-22drm/i915: Allow contexts to share a single timeline across all enginesChris Wilson9-42/+138
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.

2019-03-22drm/i915: Introduce the i915_user_extension_methodChris Wilson5-0/+135
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.
