CPUID command 80000021 unsupported

[dborel]

Spotify (with the bundled libcef) from https://repository-origin.spotify.com/pool/non-free/s/spotify-client works great on my rpi5 with latest raspbian, but it crashes with the following on my rpi4:

[BOX64] Warning, CPUID command 80000021 unsupported (ECX=00000000)
Trace/breakpoint trap

I don't think this message is linked to your issue. Pretty sure the same message appears on your Pi5 run. YOu should run with BOX64_LOG=1 and BOX64_SHOWSEGV=1 and copy/paste the log here for more info.

I don't have v4l2-request yet. Trying to build that. Not sure if it helps, but vainfo says:

The signal you are having is a SIGILL, triggered by 0F 0B opcode wich is UD2, an opcode that will trigger SIGILL by design. This is done on purpose by libcef, something is not right and libcef just abort. You are on a 4K pagesize right? because libcef will not run on 16K pagesize.

getconf PAGE_SIZE says 4096. System is on default settings of wayland, v3d GL device, 2GB swap. Full log attached.

One thing I noticed was TLS. It's 1592B, right up against the limit, which I think is ~1664B. readelf -Wl libcef.so | grep TLS shows this:

I got spotify to launch on rpi4 by commenting out "BOX64_DYNAREC_BIGBLOCK=0" in the [spotify] section of /etc/box64.box64rc. However, it still says "No internet connection detected. (Error code: accounts:4)" and complains about OPENSSL_memory_alloc, free, get_size (among others) as "Weak Symbol .. not found". EDIT: those seem to be minor OpenSSL vs BoringSSL differences. But the "[BOX64] Warning: Unsupported libc Syscall 0x1BC (444)" is landlock failing, which might cut off network.
