Re: arm: cortex_r: config_userspace: nested interrupt level is not decremented following syscall
Phil Erwin Jr
I opened GH issue #26912, and Stephanos is assigned to it.
My platform is an internal chip, that has an R5 core. I'm fairly certain that one of our team members uses QEMU, though, so I'll check with him to see if we need to up-stream anything to get that working. It sure would be nice to close this testing hole with each upgrade.

Hi Phil, can you open a GH issue on this? Stephanos or maybe Ioannis may want to take a look at it.
Also, what platform do you use to test user mode on cortex-R? qemu_cortex_r5 doesn't work with it (gaps in emulation support for the MPU perhaps?)
