When compiling qemu-fuzz-i386 on aarch64 host, clang reported the following error: ../util/cacheflush.c:38:44: error: value size does not match register size specified by the constraint and modifier [-Werror,-Wasm-operand-widths] asm volatile("mrs\t%0, ctr_el0" : "=r"(save_ctr_el0));

[Bug 1908450] Re: ide/core.c ATA Major Version reporting incorrect

for what it's worth, i have yet to see a driver actually check this field. I have seen a ton of code (OVMF and others) detect other information and just straight up say "I'm in QEMU" and YOLO a bunch of things like assuming DMA is available and such, so I somewhat doubt anyone *actually* checks

[Bug 1908450] Re: ide/core.c ATA Major Version reporting incorrect

I doubt we truly implement *any* standard precisely correctly, but if we are advertising support for ATA7 and it works, I'd rather just fix the comment to keep behavior the same. It probably was a mistake in the original commit from ... sometime before 2006, but if nothing is observably broken,

[PATCH v2] linux-user: Remove obsolete F_SHLCK and F_EXLCK translation

These lock types are unsupported by Linux since v2.2[0][1] and always return EINVAL (except on SPARC up until v2.6, which just warned). musl libc does not define these constants, so just remove them from the translation cases. [0]

[RFC PATCH v3 5/6] virtio-net: Added eBPF RSS to virtio-net.

From: Andrew When RSS is enabled the device tries to load the eBPF program to select RX virtqueue in the TUN. If eBPF can be loaded the RSS will function also with vhost (works with kernel 5.8 and later). Software RSS is used as a fallback with vhost=off when eBPF can't be loaded or when hash

[RFC PATCH v3 4/6] ebpf: Added eBPF RSS loader.

[RFC PATCH v3 0/6] eBPF RSS support for virtio-net

This set of patches introduces the usage of eBPF for packet steering and RSS hash calculation: * RSS(Receive Side Scaling) is used to distribute network packets to guest virtqueues by calculating packet hash * Additionally adding support for the usage of RSS with vhost The eBPF works on kernels

[RFC PATCH v3 3/6] ebpf: Added eBPF RSS program.

From: Andrew RSS program and Makefile to build it. The bpftool used to generate '.h' file. The data in that file may be loaded by libbpf. EBPF compilation is not required for building qemu. You can use Makefile if you need to regenerate rss.bpf.skeleton.h. Signed-off-by: Yuri Benditovich
