Hi Marek,
Hi,
I've got a patch in the same spirit in downstream.
The test campaign reveals performance issues with this patch.
In fact, hard IRQ have been introduced in stm32-usart driver to solve
performance issues due to short FIFO size (16 bytes).
We are currently testing another patch, similar as your RFC proposition,
for RT context.
But results are not ready yet. We can wait them before merging this big
change into driver ?
Can you post your patch as an RFC so others can test as well ?
