| |
Hi Greg,
This is the pull request containing fixes for 5.2-rc2/3. It is now correctly rebased on your char-misc-linux branch.
It supersedes the pull request from 12/5, so you can discard that pull request, as I see you didn't merge it anyway.
It contains 3 fixes and 1 change to a new IOCTL that was introduced to kernel 5.2 in the previous pull requests.
See the tag comment for more details.
Thanks, Oded

habanalabs: Avoid using a non-initialized MMU cache mutex (2019-05-24 22:46:15 +0300)
---------------------------------------------------------------- This tag contains the following fixes:
- Halt debug engines when user process closes the FD. We can't allow the device to issue transactions for a user which doesn't exists anymore.
- Fix various security holes in debugfs API.
- Add a new opcode to the DEBUG IOCTL API. The opcode is designed for setting the device into and out of debug mode. Although not a fix per-se, because this is a new IOCTL which is upstreamed in kernel 5.2, I think this is justified at this point because we won't be able to change the API later.
- Fix a bug where the code used an uninitialized mutex

Oded Gabbay (1): uapi/habanalabs: add opcode for enable/disable device debug mode
