This package builds and installs the Linux kernel driver for
|
the Mali GPU on Allwinner platforms, compatible with recent
|
Linux kernels (>= 4.4). Note that it should be installed
|
together with the corresponding userspace OpenGL libraries,
|
which are provided as binaries only at:
|
https://github.com/bootlin/mali-blobs
|
|
sunxi-mali-mainline-driver requires a Linux kernel >= 4.4
|
with the following options enabled:
|
|
- CONFIG_CMA
|
- CONFIG_DMA_CMA
|
|
starting from Linux Kernel >= 4.20 following options must be
|
enabled:
|
- CONFIG_DRM_FBDEV_LEAK_PHYS_SMEM
|
|
The following kernel command line options must be passed:
|
|
- drm_kms_helper.drm_leak_fbdev_smem = 1
|
since drm_kms_helper.drm_leak_fbdev_smem is set to 0 by
|
default
|
|
- drm_kms_helper.drm_fbdev_overalloc >= 200
|
since the driver requires at least double buffering and
|
fails to work with the default value(100).
