Hi Dave, A few comments below: > + for (i = 0; i < PAGES_PER_SECTION; i++) { Performance wise, this is unfortunate that we have to add this loop for every hot-plug. But, I do like the finer hot-plug granularity that you achieve, and do not have a better suggestion how to avoid this loop.

[PATCH 11/15] tty: hvc: hvc_poll break hv read loop

Avoid looping with the spinlock held while there is read data being returned from the hv driver. Instead note if the entire size returned by tty_buffer_request_room was read, and request another read poll. This limits the critical section lengths, and provides more even service to other consoles

[PATCH 04/15] powerpc/powernv: opal-kmsg use flush fallback from console code

Use the more refined and tested event polling loop from opal_put_chars as the fallback console flush in the opal-kmsg path. This loop is used by the console driver today, whereas the opal-kmsg fallback is not likely to have been used for years. Use WARN_ONCE rather than a printk when the fallback

[PATCH 00/15] hvc and powerpc opal console latency reduction

I'm seeing scattered reports of hard lockups triggering in the OPAL console code. I haven't got a full latency trace -- they are difficult to reproduce and sometimes just show up in dmesg of a bug report when the system is having other issues. But it does seem like there are some improvements that

[PATCH 01/15] powerpc/powernv: opal_put_chars partial write fix

The intention here is to consume and discard the remaining buffer upon error. This works if there has not been a previous partial write. If there has been, then total_len is no longer total number of bytes to copy. total_len is always "bytes left to copy", so it should be added to written bytes.

[PATCH 09/15] tty: hvc: remove unexplained "just in case" spin delay

This delay was in the very first OPAL console commit 6.5 years ago, and came from the vio hvc driver. The firmware console has hardened sufficiently to remove it. Reviewed-by: Benjamin Herrenschmidt Signed-off-by: Nicholas Piggin ---

[PATCH 08/15] powerpc/powernv: implement opal_put_chars_atomic

The RAW console does not need writes to be atomic, so relax opal_put_chars to be able to do partial writes, and implement an _atomic variant which does not take a spinlock. This API is used in xmon, so the less locking that is used, the better chance there is that a crash can be debugged. Cc:
