Hi Qemu developers,
I am trying to bootup a loongarch64 Linux kernel in Qemu 7.1.0-rc2.
The problem is I get no output when using following command:
qemu-system-loongarch64 -M virt -nographic -kernel vmlinux
You can find my vmlinux initramfs here:
https://debug.openadk.org/vmlinux
It is cross-co

Hello,
I don't know if this is the right place to submit this report,
but I have a problem with my attempt to check the 7.1.0 release candidate
for linux user powerpc CPU.
I am testing a simple executable, compiled with Free Pacal compiler,
but also linked to libc.
This is what I obtain w

Hello,
I'm currently looking into implementing a 'file:' uri for migration save
in qemu. Ideally the solution will be O_DIRECT compatible. I'm aware of
the branch https://gitlab.com/berrange/qemu/-/tree/mig-file. In the
process of brainstorming how a solution would like the a couple of

It's too costly to write all the BAT to the disk. Let the flush function
write only dirty blocks.
Use parallels_set_bat_entry for setting a BAT entry and marking a relevant
block as dirty.
Move bdrv_co_flush call outside the locked area.
v2: Patch order was changed so the replacement is done in pa
v2: Move fragmentation counting code to this function too.

Fix image inflation when offset in BAT is out of image.
Replace whole BAT syncing by flushing only dirty blocks.
Move all the checks outside the main check function in
separate functions
Use WITH_QEMU_LOCK_GUARD for more clean code.
