minigbm: vc4: Fix error log for DRM_IOCTL_VC4_CREATE_BO

2020-07-27T22:24:20+00:00

An ioctl call is made to DRM_IOCTL_VC4_CREATE_BO. On error, it
incorrectly reports that DRM_IOCTL_VC4_GEM_CREATE has failed. This fixes
the log message.

minigbm: Fix consistency in return values

2019-03-26T11:43:19+00:00

minigbm functions don't use errno; however drmIoctl does. So we need
to return -errno instead of returning exactly what drmIoctl returns.

Use Android log system in helpers.c.

2018-03-22T06:23:37+00:00

This code might be loaded by a daemonized process now, so the existing
logging to stderr goes nowhere. It's better to use the Android logger.

minigbm: make drv_add_combinations return nothing

2017-11-16T21:52:02+00:00

Two reasons for this:

	1) We can use drv_array for driver combinations (see next patch)
	2) It's less verbose.

minigbm: refactor and rename mapping struct

2017-11-09T06:21:56+00:00

Since some drivers (AMDGPU, Tegra) may have to do expensive tiling
and detiling operations, we should try to take advantage of the
access regions passed in by gralloc and gbm. Let's refactor struct
map_data so we can separate the actual mapping and access region.

Here is the Coccinelle rule used in this change:

@@ struct map_info *M; @@
-   (M)
+   M->vma

In addition, struct map_data was also renamed to struct mapping.

minigbm: re-const-ify driver backends

2017-11-08T23:10:09+00:00

minigbm driver creation needs to be re-entrant (see CL:674528). Let's
re-constify to make this behavior explicit.
