Hello,
is there the possibility of using a DMA engine channel from userspace?
Something like:
- configure DMA using ioctl() (or whatever configuration mechanism)
- read() or write() to trigger the transfer
Let me add one more

Hello,
is there the possibility of using a DMA engine channel from userspace?
Something like:
- configure DMA using ioctl() (or whatever configuration mechanism)
- read() or write() to trigger the transfer

a new function to handle timeout
- modified the current ocores_process() function in order to be protected
by the new spinlock
Like this it is obvious at first sight that this locking serializes
the execution of ocores_process() and ocores_process_timeout()

If the Interrupt Flag (IF) is not set, we should not handle the IRQ:
- the line can be shared with other devices
- it can be a spurious interrupt
To avoid reading twice the status register, the ocores_process() function
expects it to be read by the caller.

not looping at all. But for reading an 4K AT24 EEPROM, it increased
the read time by 10ms, from 424ms to 434ms. So we should probably keep
with 8.

This patch set provides improvements to the i2c-ocore driver.
[V6 -> V7]
- restore accidentally removed 'reviewed-by' tags in changelog
[V5 -> V6]
- remove redundant code introduced in V5 (double read control register)
[V4 -> V5]
- deterministic status of IEN bit in register "CONTROL" at the
if there are other similar cases.
I do not know Perl, so I cannot investigate more, but I have a practical
example. I have this simple patch applied on my tree that introduces a spell
