Subject: [PATCH] staging: vc04_services: Add 32-bit compatibility ioctls
VCHIQ/vc04_services has a userland device interface
that includes ioctls. The ioctls are very pointer
dependent, so in the case of 32-bit running on top
of a 64-bit kernel, it is necessary to deal with
the structure differences.
The solution to this is that the standard ioctl numbering
mechanism includes a data size field. Since the size of the
userland data structures change between 32-bit and 64-bit,
the length of the data can be used to easily determine the
type of application.
On 64-bit ONLY - Compatibility ioctls are defined.
Example:
Native ioctl:
_IOW(VCHIQ_IOC_MAGIC, 4, VCHIQ_QUEUE_MESSAGE_T)
Compatibility ioctl:
_IOW(VCHIQ_IOC_MAGIC, 4, VCHIQ_QUEUE_MESSAGE32_T)
For this particular ioctl, the two ioctls share a different
code path. For some ioctls, it is much easier to share
the same code path and only occasionally handle the differences.
This is typically done by copying the 32-bit datastructure into
the 64-bit datastructure after it has been read from userland.
Testing:
1. vchiq_test -f 10 and vchiq_test -p 1 were run from a native
64-bit OS(debian sid) to check for regressions.
2. vchiq_test -f 10 and vchiq_test -p 1 where run from a 32-bit
chroot install from the same OS to test the compatibility ioctls.
Both test cases now pass.
