blockdev-reopen will have to wait for it to complete in the polling

'Or' the IRQs coming from the QSPI and QSPI DMA models. This is done for
avoiding the situation where one of the models incorrectly deasserts an
interrupt asserted from the other model (which will result in that the IRQ
is lost and will not reach guest SW).

While changing to the use of cfg_ptr, the conditions for REQUIRE_ZB[ABCS]
inadvertently became inverted and slipped through the initial testing (which
used RV64GC_XVentanaCondOps as a target).
This fixes the regression.
Tested against SPEC2017 w/ GCC 12 (prerelease) for RV64GC_zba_zbb_zbc_zbs.

We start the reconnect delay timer to cancel the reconnection attempt
after a while. Once nbd_co_do_establish_connection() has returned, this
attempt is over, and we no longer need the timer.
Delete it before returning from nbd_reconnect_attempt(), so that it does
not persist beyond the I/O reque
This is a rather simple class that allows creating a QSD instance
running in the background and stopping it when no longer needed.
The __del__ handler is a safety net for when something goes so wrong in
a test that e.g. the tearDown() method is not called (e.g. setUp()
launches the QSD, but then l
We start the open timer to cancel the connection attempt after a while.

Hi,
I’ve sent an RFC for this before, which can be found here:
https://lists.nongnu.org/archive/html/qemu-block/2022-01/msg00765.html
...and is basically patch 6 in this series.
That was an RFC for two reasons:
(1) I didn’t know what to do with the two timers that the NBD BDS has

Our two timers must not remain armed beyond nbd_clear_bdrvstate(), or
they will access freed data when they fire.
This patch is separate from the patches that actually fix the issue
(HEAD^^ and HEAD^) so that you can run the associated regression iotest
(281) on a configuration that reproducibly e
Put an NBD block device into an I/O thread, and then read data from it,
hoping that the NBD connection will yield during that read. When it
does, the coroutine must be reentered in the block device's I/O thread,
which will only happen if the NBD block driver attaches the connection's

Prior to "block/nbd: Delete reconnect delay timer when done" and
"block/nbd: Delete open timer when done", both of those timers would
remain scheduled even after successfully (re-)connecting to the server,
and they would not even be deleted when the BDS is deleted.

Unlike most virtio features ACCESS_PATFORM is considered mandatory, i.e.
the driver must accept it if offered by the device. The virtio
specification says that the driver SHOULD accept the ACCESS_PLATFORM
feature if offered, and that the device MAY fail to operate if
ACCESS_PLATFORM was offered but

The main news here are the usage of .allowed() and .require() methods for
features. These simplify a lot the generation of errors when features
depend on the results of compile or OS tests. The reduction in LoC is
smaller than past conversions, but still not bad.
There aren't many tests left in
The method is now in 0.59, using it simplifies some boolean conditions.
The other new methods .require() and .disable_auto_if() can be used too,
but introducing them is not just a matter of search-and-replace.
