In function enable_stream_features(), the variable "old_downspread.raw"
could be uninitialized if core_link_read_dpcd() fails, however, it is
used in the later if statement, and further, core_link_write_dpcd()
may write random value, which is potentially unsafe.

it does not check the return value and directly use the "type" in

Log engine resets done by the GuC firmware in the similar way it is done
by the execlists backend.
This way we have notion of where the hangs are before the GuC gains
support for proper error capture.

Hi,
I'm just letting you know that drm-misc-next-fixes is now open for bug
fixes. -rc6 will presumably be tagged this weekend, which means that
drm-next is in feature freeze until the next -rc1 comes out.
The transition from/to drm-misc-fixes-next often results in patches that
are applied to

IOMMU/DT folks, any thoughts about this approach? The patches that are

FWIW it looks fairly innocuous to me. I don't understand host1x -

Currently we allow rediculous ammounts of kernel memory being allocated
via the etnaviv GEM_SUBMIT ioctl, which is a pretty easy DoS vector. Put
some reasonable limits in to fix this.
The commandstream size is limited to 64KB, which was already a soft limit
on older kernels after which the kernel

Currently, there is no size check for allocation.
If the alloc size is larger than DRAM, it will cause OOM issue.
Besides, if it runs on a process that won't be killed by OOM flow, it will
cause a kernel exception finally, and we couldn't find the correct
memory usage by dma-buf
