Subject: [PATCH v2 00/27] maintainer updates for 9.0 pre-PR (tests, plugin register support)
Date: Fri, 23 Feb 2024 16:21:35 +0000 [thread overview]
Message-ID: <20240223162202.1936541-1-alex.bennee@linaro.org> (raw)
The test patch is a simple house keeping one to clean up some
inadvertent GPLv3 tagging to GPLv2-or-later. I've also increased the
timeout for check-tcg due to TCI timesouts.
The main bulk of this series is register reading support for TCG
plugins. The main change to the API is that the get/read_register
functions are now implicitly vCPU context only so have dropped the
vcpu index parameter and use current_cpu instead. This avoids the need
for locking the gdbstub structures in case there is a cross-vCPU
access.
I've pulled in some patches from Pierrick's inline enhancement series
that allow this to happen (making sure the init callback is in the
vCPU context).
Changes for v2:
After lots of back and forth in the last review I've dropped trying to
be clever with CPUClass as it was pointed out even with a common
CPUClass we might see different sets of registers depending on what
features are enabled on a CPU. Now I just have a hash per CPUState
(stored in the new CPUPluginState structure) with a simple reg_num key.
I also fixed a bug in nios2-linux-user.
The following still need review:
contrib/plugins: extend execlog to track register changes
tests/tcg: expand insn test case to exercise register API
plugins: create CPUPluginState and migrate plugin_mask
gdbstub: expose api to find registers
linux-user: ensure nios2 processes queued work
tests/tcg: bump TCG test timeout to 120s
But I'd like to get this merged soon so its not a mad rush before soft
freeze and so we can get the new inline support stabilised and merged.
Alex.
