* gbm: Use unsigned for BO offset getterDaniel Stone2017-03-231-1/+1
| | | | | | | | | | | | | | | | The actual offset returned is uint32_t, however int64_t was used as the return type from gbm_bo_get_offset to allow negative returns to signal errors to the caller. In case of an error getting the offset, the user will also be unable to get the handle/FD, and thus have nothing to offset into. This means that returning 0 as an error value is harmless, allowing us to change the return type to uint32_t in order to avoid signed/unsigned confusion in callers.

| | | | | | | | | | | | | | | | | | | | | | | | | This patch originally had i965 specific code and was named: commit 61cd3c52b868cf8cb90b06e53a382a921eb42754 Author: Ben Widawsky <[email protected]> Date: Thu Oct 20 18:21:24 2016 -0700 gbm: Get modifiers from DRI To accomplish this, two new query tokens are added to the extension: __DRI_IMAGE_ATTRIB_MODIFIER_UPPER __DRI_IMAGE_ATTRIB_MODIFIER_LOWER The query extension only supported 32b queries, and modifiers are 64b, so we needed two of them.

* gbm: Introduce modifiers into surface/bo creationBen Widawsky2017-03-151-2/+37
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The idea behind modifiers like this is that the user of GBM will have some mechanism to query what properties the hardware supports for its BO or surface. This information is directly passed in (and stored) so that the DRI implementation can create an image with the appropriate attributes. A getter() will be added later so that the user GBM will be able to query what modifier should be used. Only in surface creation, the modifiers are stored until the BO is actually allocated. In regular buffer allocation, the correct modifier can (will be, in future patches be chosen at creation time. v2: Make sure to check if count is non-zero in addition to testing if calloc fails. (Daniel) v3: Remove "usage" and "flags" from modifier creation. Requested by Kristian. v4: Take advantage of the "INVALID" modifier added by the GET_PLANE2 series. v5: Don't bother with storing modifiers for gbm_bo_create because that's a synchronous operation and we can actually select the correct modifier at create time (done in a later patch) (Jason) v6: Make modifier condition outside the check so that dri_use will work properly (Jason) Cc: Kristian Høgsberg <[email protected]> References (v4): https://lists.freedesktop.org/archives/intel-gfx/2017-January/116636.html Signed-off-by: Ben Widawsky <[email protected]> Reviewed-by: Eric Engestrom <[email protected]> (v1) Reviewed-by: Jason Ekstrand <[email protected]> Acked-by: Daniel Stone <[email protected]>

* gbm: Add gbm_bo_write entry pointKristian Høgsberg2012-05-031-0/+19
| | | | | | | | | | | | | | | | This new gbm entry point allows writing data into a gbm bo. The bo has to be created with the GBM_BO_USE_WRITE flag, and it's only required to work for GBM_BO_USE_CURSOR_64X64 bos. The gbm API is designed to be the glue layer between EGL and KMS, but there was never a mechanism initialize a buffer suitable for use with KMS hw cursors. The hw cursor bo is typically not compatible with anything EGL can render to, and thus there's no way to get data into such a bo. gbm_bo_write() fills that gap while staying out of the efficient cpu->gpu pixel transfer business.

| | | | | | | | | | | | The idea here is to be able to create an egl window surface from a gbm_surface. This avoids the need for the surfaceless extension and lets the EGL platform handle buffer allocation, while keeping the user in charge of somehow presenting the buffers (using kms page flipping, for example). gbm_surface_lock_front_buffer() locks a surface's front buffer and returns a gbm bo representing it. This bo should later be returned to the gbm surface using gbm_surface_release_buffer().
