Here's a little cleanup of VCHI this morning, working toward building
on aarch64 (not there yet) and adding some notes on what I think we
need to do with the driver.
Eric Anholt (5):
staging/vchi: Fix build error in debugfs ops on aarch64.
staging/vchi: Fix build warnings when formatting pointers on aarch64.
staging/vchi: Fix some pointer math for 64-bit.
staging/vchi: Add a TODO file of things I know we need to deal with.
MAINTAINERS: Add the staging vchiq driver as a bcm2835 responsibility.

file_operations.write returns a ssize_t, which worked out fine on 32
bit but errors out on 64 bit.

The code was generally using "%x" to print and "(unsigned int)" to
cast the pointers, but we have %p for printing pointers in the same
format without any broken casts.

* [PATCH 2/5] staging/vchi: Fix build warnings when formatting pointers on aarch64.
@ 2016-10-17 19:44 ` Eric Anholt
0 siblings, 0 replies; 26+ messages in thread
From: Eric Anholt @ 2016-10-17 19:44 UTC (permalink / raw)
To: linux-arm-kernel
The code was generally using "%x" to print and "(unsigned int)" to
cast the pointers, but we have %p for printing pointers in the same
format without any broken casts.

I've left out the downstream HDMI audio driver from the "to be
imported" section, as we'll want to handle it natively in vc4. The
downstream kernel will likely continue to use that driver for a while
due to using the interim "vc4 firmware KMS" mode while vc4 gets its
featureset (such as HDMI audio!) completed.
I've also left out VC-CMA, which appears to be about having Linux
manage a CMA area that the firmware gets to make allocations out of.
I'm not clear on if this is useful (the firmware's need for memory
drops massively with vc4 present, and may drop even more depending on
how we resolve dmabuf handling for camera and video decode)

I already did this work, it's all checked into my tree, and is in
linux-next now. You were cc:ed on the patches as well.
Also, please use "%pK" for kernel pointers, you never want to print an
address to userspace unless debugging is enabled, as it is a security
leak.

I actually haven't seen any of those messages about the patches. It
looks like it's actually that notmuch is still failing to parse some
mails (they apparently disagree with postfix on how maildir files should
be formatted, so they just drop some mail on the floor).
I did check the staging-testing branch before I started, since that's
where things were last I knew, and didn't know it had moved to -next.

But staging-testing has those fixes in it (it gets pulled into -next).

VC-CMA allows unused memory from the gpu to be used as CMA on the
linux side in a dynamic way.
However it has always had some issues, so is not enabled by default.
The main reason for wanting the gpu side to have significant memory is
for textures used
by the gpu side 3D driver. In the vc4-kms-v3d driver world the
requirement for significant amounts
of gpu memory goes away.
For most camera and video decode usage, the default gpu_mem=64M is sufficient.
As such, I'd ignore VC-CMA upstream, and assume it will disappear
downstream eventually.
vc_mem is used by vcdbg to get gpu side addresses for debug features
(e.g. extracting gpu debug log and viewing its memory heaps and vchiq state).
vcsm is currently used for allocating arm accessible memory from the gpu.
It is used by mmal when in zero copy mode (typically enabled) and as Eric says,
is likely to be used for dmabuf allocation.
