[PATCH 6.1 298/600] drm/msm/a2xx: Call adreno_gpu_init() earlier

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



6.1-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Fabio Estevam <festevam@xxxxxxx>

[ Upstream commit db07ce5da8b26bfeaf437a676ae49bd3bb1eace6 ]

The adreno_is_a20x() and adreno_is_a225() functions rely on the
GPU revision, but such information is retrieved inside adreno_gpu_init(),
which is called afterwards.

Fix this problem by caling adreno_gpu_init() earlier, so that
the GPU information revision is available when adreno_is_a20x()
and adreno_is_a225() run.

Tested on a imx53-qsb board.
