Subject: [PATCH 0/2] esp: minor fixes for older Linux versions
Date: Tue, 18 May 2021 22:25:09 +0100 [thread overview]
Message-ID: <20210518212511.21688-1-mark.cave-ayland@ilande.co.uk> (raw)
Following on from the ESP changes in QEMU 6.0 someone pointed out that the old
Linux 2.6 ESP driver as used in Aurelian's SPARC image at
https://people.debian.org/~aurel32/qemu/sparc/ emits a constant stream of
"esp0: STEP_ASEL for tgt 0" messages to the console during boot.
These patches solve the issue so that the older image is able to boot cleanly
once again. The first patch is a genuine bug fix for the QEMU 6.0 changes whilst
the second works around the delayed bus phase change when deferring IO transfers
from the end of the command phase to the start of the information transfer
phase.
I've tested this using the extended suite of images used for the QEMU 6.0 changes
and confirmed that there are no other regressions.
