Merge tag 'pull-ppc-20221029' of https://gitlab.com/danielhb/qemu into staging
ppc patch queue for 2022-10-29:
This queue has the second part of the ppc4xx_sdram cleanups, doorbell
instructions for POWER8, new pflash handling for the e500 machine and a
Radix MMU regression fix.
It also has a lot of performance optimizations in the PowerPC emulation
done by the researchers of the Eldorado institute. Between using gvec
for VMX/VSX instructions, a full rework of the interrupt model and PMU
optimizations, they managed to drastically speed up the emulation of
powernv8/9/10 machines. Here's an example with avocado tests:
- with master:
tests/avocado/boot_linux_console.py:BootLinuxConsole.test_ppc_powernv8:
PASS (38.89 s)
tests/avocado/boot_linux_console.py:BootLinuxConsole.test_ppc_powernv9:
PASS (43.89 s)
- with this queue applied:
tests/avocado/boot_linux_console.py:BootLinuxConsole.test_ppc_powernv8:
PASS (21.23 s)
tests/avocado/boot_linux_console.py:BootLinuxConsole.test_ppc_powernv9:
PASS (22.58 s)
Other ppc machines, like pseries, also had a noticeable performance
boost.
