Subject: [PATCH 00/14] arm_gicv3_its: Implement MOVI and MOVALL commands
Date: Sat, 22 Jan 2022 18:24:30 +0000 [thread overview]
Message-ID: <20220122182444.724087-1-peter.maydell@linaro.org> (raw)
I noticed while working on the new-in-GICv4 ITS commands
that we'd forgotten to implement the GICv3 MOVI and MOVALL
commands. These move interrupts from one redistributor to
another; Linux doesn't use MOVALL but does use MOVI if
it wants to power down a CPU (when it needs to migrate
interrupts formerly targeting that CPU to a different one).
This patchseries starts with a couple of patches that I
found useful to improve the debug logging when I was
writing this. It then has a collection of fixes for various
minor bugs that I noticed while I was in the code (including
yet another fix to the table lookup bounds checking...).
Finally the last two patches implement the two new commands.
thanks
