Peter Maydell	dc249aaf57	misc: Clean up includes This commit deals with various .c files that included system headers that are already pulled in by osdep.h, where the .c file includes osdep.h already itself. This commit was created with scripts/clean-includes: ./scripts/clean-includes '--git' 'misc' 'hw/core' 'semihosting' 'target/arm' 'target/i386/kvm/kvm.c' 'target/loongarch' 'target/riscv' 'tools' 'util' All .c should include qemu/osdep.h first. The script performs three related cleanups: * Ensure .c files include qemu/osdep.h first. * Including it in a .h is redundant, since the .c already includes it. Drop such inclusions. * Likewise, including headers qemu/osdep.h includes is redundant. Drop these, too.

Vladimir Sementsov-Ogievskiy	1ed8903916	treewide: handle result of qio_channel_set_blocking() Currently, we just always pass NULL as errp argument. That doesn't look good. Some realizations of interface may actually report errors. Channel-socket realization actually either ignore or crash on errors, but we are going to straighten it out to always reporting an errp in further commits. So, convert all callers to either handle the error (where environment allows) or explicitly use &error_abort. Take also a chance to change the return value to more convenient bool (keeping also in mind, that underlying realizations may return -1 on failure, not -errno). Suggested-by: Daniel P.

Markus Armbruster	720a0e417e	cleanup: Re-run return_directly.cocci Coccinelle's indentation of virt_create_plic() results in a long line. Avoid that by mimicking the old indentation manually. Don't touch tests/tcg/mips/user/. I'm not sure these files are ours to make style cleanups on. They might be imported third-party code, which we should leave as is to not complicate future updates.

Paolo Bonzini	2a99c2ba82	qemu-vmsr-helper: implement --verbose/-v Similar to qemu-pr-helper, do not print errors from the socket handling loop unless a --verbose or -v option is provided explicitly on the command line. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>	2 years ago
Paolo Bonzini	768a28394c	qemu-vmsr-helper: fix socket loop breakage Between v5 and v6 of the series, the socket loop of qemu-vmsr-helper was changed to allow sending multiple requests on the same socket. Unfortunately, the condition of the while loop is botched and the loop will never be entered. Clean it up, and also unify the handling of error reporting.

Anthony Harivel	84369d7621	tools: build qemu-vmsr-helper Introduce a privileged helper to access RAPL MSR. The privileged helper tool, qemu-vmsr-helper, is designed to provide virtual machines with the ability to read specific RAPL (Running Average Power Limit) MSRs without requiring CAP_SYS_RAWIO privileges or relying on external, out-of-tree patches. The helper tool leverages Unix permissions and SO_PEERCRED socket options to enforce access control, ensuring that only processes explicitly requesting read access via readmsr() from a valid Thread ID can access these MSRs. The list of RAPL MSRs that are allowed to be read by the helper tool is defined in rapl-msr-index.h. This list corresponds to the RAPL MSRs that will be supported in the next commit titled "Add support for RAPL MSRs in KVM/QEMU." The tool is intentionally designed to run on the Linux x86 platform. This initial implementation is tailored for Intel CPUs but can be extended to support AMD CPUs in the future.
