Sometimes ringbuffer timer is not getting updated due to
race with the preemption. This can cause dispatcher to
detect false timeout gpu faults. Remove preempt state
check in adreno_dispatch_process_drawqueue(), which will
allow to update ringbuffer timeout value irrespective of
the preemption state.
If the preemption completes successfully, preemption logic
updates timer for new_rb. We don’t need to care if it is
not updated for prev_rb. If preemption in-progress timer
will be updated for cur_rb in adreno_dispatch_process_drawqueue().
In both cases we are taking care to update ringbuffer timer.
Hence we don’t need to check preemption state.

Move the QSEE handle from user space to kernel space.
In addition, fix possible overflow, when checking that
the command and response buffers fit in the shared buffer.

There is a potential race between fuse_dev_do_write()
and request_wait_answer() contexts as shown below:
TASK 1:
__fuse_request_send():
|--spin_lock(&fiq->waitq.lock);
|--queue_request();
|--spin_unlock(&fiq->waitq.lock);
|--request_wait_answer():
|--if (test_bit(FR_SENT, &req->flags))
<gets pre-empted after it is validated true> TASK 2:
fuse_dev_do_write():
|--clears bit FR_SENT,
|--request_end():
|--sets bit FR_FINISHED
|--spin_lock(&fiq->waitq.lock);
|--list_del_init(&req->intr_entry);
|--spin_unlock(&fiq->waitq.lock);
|--fuse_put_request();
|--queue_interrupt();
<request gets queued to interrupts list>
|--wake_up_locked(&fiq->waitq);
|--wait_event_freezable();
<as FR_FINISHED is set, it returns and then
the caller frees this request>
Now, the next fuse_dev_do_read(), see interrupts list is not empty
and then calls fuse_read_interrupt() which tries to access the request
which is already free'd and gets the below crash:
[11432.401266] Unable to handle kernel paging request at virtual address
6b6b6b6b6b6b6b6b
...
[11432.456168] PC is at __list_del_entry+0x6c/0xc4
[11432.463573] LR is at fuse_dev_do_read+0x1ac/0x474
...
[11432.679999] __list_del_entry+0x6c/0xc4

[11432.699082] __vfs_read+0xc0/0xe8
[11432.704459] vfs_read+0x90/0x108
As FR_FINISHED bit is set before deleting the intr_entry with input
queue lock in request completion path, do the testing of this flag and
queueing atomically with the same lock in queue_interrupt().

There is a chance for a CPR controller to use the run-time calibrated
step_quot of lower modes for higher modes. This can sometimes lead
to closed-loop voltage getting stuck at open-loop voltage. To avoid
this, configure APC0/1 and GFX CPR controllers in sdm660 to first use
the default step_quot and then later switch to the run-time calibrated
step_quot.
