drm/msm: Fix error handling crashes seen when VRAM allocation fails

2016-11-04T15:51:37Z

If VRAM allocation fails, the error handling path crashes in msm_drm_uninit(). The following changes are made to fix this: msm_gem_shrinker_cleanup() is fixed to unregister the shrinker only if it was init-ed in the first place. Before calling kms->funcs->destroy(), we check if kms->funcs is also non-NULL. This is needed for MDP5, since during msm_drm_int(), priv->kms becomes non-NULL early, but msm_kms_init() is called on it only later in mdp5_kms_init().

drm/msm/mdp5: no scaling support on RGBn pipes for 8x16

2016-11-02T14:49:43Z

Looks like cut/paste error from the other device cfgs (which do support scaling on RGBn pipes). Signed-off-by: Rob Clark

drm/msm/mdp5: handle non-fullscreen base plane case

2016-11-02T14:49:33Z

If the bottom-most layer is not fullscreen, we need to use the BASE mixer stage for solid fill (ie. MDP5_CTL_BLEND_OP_FLAG_BORDER_OUT). The blend_setup() code pretty much handled this already, we just had to figure this out in _atomic_check() and assign the stages appropriately. Also fix the case where there are zero enabled planes, where we also need to enable BORDER_OUT. Signed-off-by: Rob Clark

drm/msm: Set CLK_IGNORE_UNUSED flag for PLL clocks

2016-11-02T14:48:09Z

The DSI/HDMI PLLs in MSM require resources like interface clocks, power domains to be enabled before we can access their registers. The clock framework doesn't have a mechanism at the moment where we can tie such resources to a clock, so we make sure that the KMS driver enables these resources whenever a PLL is expected to be in use. One place where we can't ensure the resource dependencies are met is when the clock framework tries to disable unused clocks. The KMS driver doesn't know when the clock framework calls the is_enabled clk_op, and hence can't enable interface clocks/power domains beforehand. We set the CLK_IGNORE_UNUSED flag for PLL clocks for now. This needs to be revisited, since bootloaders can enable display, and we would want to disable the PLL clocks if there isn't a display driver using them.

drm/msm/dsi: Queue HPD helper work in attach/detach callbacks

2016-11-02T14:48:09Z

The msm/dsi host drivers calls drm_helper_hpd_irq_event in the mipi_dsi_host attach/detatch callbacks. mipi_dsi_attach()/mipi_dsi_detach() from a panel/bridge driver could be called from a context where the drm_device's mode_config.mutex is already held, resulting in a deadlock. Queue it as work instead. Signed-off-by: Archit Taneja Signed-off-by: Rob Clark
