As discussed with Baolin Wang, Michal Nazarewicz and Felipe Balbi. I propose
the forced buffer alignment of OUT endpoints USB requests. This is implemented
by patches #1 and #2.
That not just simplifies the driver code, but it also prevents nasty bugs when
buflen is not aligned or even less than w
512 is the value used by wMaxPacketSize, as specified by the USB Spec. This
makes sure this driver uses, by default, the most optimal value for IN and OUT

This change makes sure that the ALSA buffers are cleaned if an endpoint

Before this change, if the internal ALSA buffer did overflow, the MIDI

The variable "req" will eventually be set to an appropriate pointer
from a call of the ptlrpc_request_alloc() function.
Thus omit the explicit initialisation which became unnecessary with
a previous update step.

This parameter was not really necessary and gadget drivers would almost always
create an inline function to pass the same value to len and default_len.
So this patch also removes duplicate code from few drivers.

My apologies in advance if I misunderstand the purposes of this patch.
IIUC, this patch adds a random gap between various mmap() mappings,
with the goal of ensuring that both the mmap base address and gaps
between pages are randomized.
If that's the goal, please note that this behavior has caused

We'd end up NULL pointer dereferencing because we didn't take the
error path out in the parent. Fixes igt vc4_lookup_fail test.

Overflow memory handling is tricky: While it's still referenced by the
BPO registers, we want to keep it from being freed. When we are
putting a new set of overflow memory in the registers, we need to
assign the old one to the last rendering job using it.
We were looking at "what's currently runn
If you exceeded the size that kmalloc would return, you'd get a dmesg
warning and an error from the job submit. We can handle much larger
allocations with vmalloc, and drm_malloc_ab makes that decision.
Fixes failure in piglit's scissor-many.

If the device was already up, a 1 is returned instead of 0. We were
erroring out, leading the 3D driver to sometimes fail at screen
initialization (generally with ENOENT returned to it).

Here are a bunch of miscellaneous fixes for 3D I've come up with while

I've got a test almost ready for large CLs.

If you managed to exceed the limit to switch to vmalloc, we'd use the
wrong free.

The BO cache will complain if BOs are still allocated when we try to
destroy it (since freeing those BOs would try to hit the cache). You
could hit this if you were to unload the module after a GPU hang.
