This patch fixes the issue due to: [ 89.572883] divide_error: 0000 [#1] SMP KASAN PTI [ 89.572897] CPU: 3 PID: 16083 Comm: repro Not tainted 5.9.0-rc7.20200930.rc1.allarch-19-g3e32d0d.syzk #5 [ 89.572902] Hardware name: QEMU Standard PC (i440FX + PIIX, 1996), BIOS 0.5.1 01/01/2011 [ 89.572934] RIP: 0010:cirrusfb_check_var+0x84/0x1260 The error happens when the pixels value is calculated before performing the sanity checks on bits_per_pixel. A bits_per_pixel set to zero causes divide by zero error. This patch moves the calculation after the sanity check. Signed-off-by:

If the DSI driver is the last to probe, component_add will try to run all the bind callbacks straight away and return the error code. However, since we depend on a power domain, we're pretty much guaranteed to be in that case on the BCM2711, and are just lucky on the previous SoCs since the v3d also depends on that power domain and is further in the probe order. In that case, the DSI host will not stick around in the system: the DSI bind callback will be executed, will not find any DSI device attached and will return EPROBE_DEFER, and we will then remove the DSI host and ask to be probed later on. But since that host doesn't stick around, DSI devices like the RaspberryPi touchscreen whose probe is not linked to the DSI host (unlike the usual DSI devices that will be probed through the call to mipi_dsi_host_register) cannot attach to the DSI host, and we thus end up in a situation where the DSI host cannot probe because the panel hasn't probed yet, and the panel cannot probe because the DSI host hasn't yet. In order to break this cycle, let's wait until there's a DSI device that attaches to the DSI host to register the component and allow to progress further. Acked-by:

User-space should avoid parsing EDIDs for metadata already exposed via other KMS interfaces and properties. For instance, user-space should not try to extract a list of modes from the EDID: the kernel might mutate the mode list (because of link capabilities or quirks for instance). Other metadata not exposed by KMS can be parsed by user-space. This includes for instance monitor identification (make/model/serial) and supported color-spaces. v2: add short explanation why user-space shouldn't do this (Brian) Signed-off-by:

The move notify callback is only used in one place, this should be removed in the future, but for now just rename it to the use case which is to notify the driver that the GPU memory is to be deleted. Drivers can be cleaned up after this separately. Reviewed-by:

Hooray for generic fbdev support, making this a oneliner. We just needed to fix preferred_depth fixed and the vmap support added first. This is useful for testing fbdev testcases in igt. Right now we only have a simple one in the fbdev testcases, which passes both info and mmap subtests. v2: Augment commit message as suggested by Melissa. Acked-by:
