Qemu-5.2.0

dodoLQ · 03-16-2021, 01:46 PM

Does anyone successfully compiled the latest release of qemu on -current? Thanks

No - did you try?

Yes, I'm using it since December without problems.

Yes. Had to apply this upstream patch to get it to work on current.

Thank you for these two patches

walecha · 03-18-2021, 01:23 AM

I'm using it on 64. Without the patches.

dodoLQ · 03-23-2021, 02:03 PM

Hi, the two patches works but i've that message:

Code:

qemu-5.2.0/configure
qemu-5.2.0/qemu.nsi
qemu-5.2.0/Kconfig
qemu-5.2.0/.gdbinit
patching file configure
patching file Makefile
patch unexpectedly ends in middle of line

I don't know if it comes from the last .diff or inside ./pc-bios/optionrom/Makefile ..
But anyway the compilation works!

MDKDIO · 03-23-2021, 03:13 PM

I just built 5.2.0, went fine here.

At the point:
qemu-5.2.0/.gdbinit

The only thing I noticed was this:
chmod: cannot operate on dangling symlink './roms/skiboot/ccan/heap/LICENSE'
chmod: cannot operate on dangling symlink './roms/edk2/EmulatorPkg/Unix/Host/X11IncludeHack'

Else from that it built fine

(Current 64-bit updated as of March 22)

This is my build list for qemu, plus those patches (thanks for the info). I'm also adding liburing since we are now using linux 5.10/5.11 and io_uring in kernel is much more stable. It's very fast with very low performance overheads (cpu/ram) for I/O. In my system, io_uring can performs GB/s I/O with nearly 0% cpu using high performance pcie gen3 nvme drive. But the drawback is I can't use io='io_uring' for windows VM. They're just went BSOD because they can't tracks their own I/O :-P
