Thank you Marc for reviewing the change and fixing the issues, I have picked up your patches and sent out v2. Tested on Cortex-A32. Best Regards, Zaid Al-Bassam On Wed, Feb 8, 2023 at 11:40 AM Marc Zyngier [off-list ref] wrote:

Currently, PMUv3 driver is only available for ARMv8 aarch64 platforms, ARMv8 running in aarch32 mode dont have access to the driver. This is, especially, a problem for ARMv8 platforms that only have aarch32 support, like the Cortex-A32.FWIW, I've pushed out my own interpretation of this series to [1], including the changes I suggested. The results seems to correctly work in a 32bit guest on a 64bit host, which is what I (used to) care about. Feel free to pick it up. M.
