[PULL 1/1] meson: fix Windows build

From: oltolm Sorry, I forgot to cc the maintainers. The build failed when run on Windows. I replaced calls to Unix programs like ´cat´, ´sed´ and ´true´ with calls to ´python´. I wrapped calls to ´os.path.relpath´ in try-except because it can fail when the two paths are on different drives. I ma

[PATCH v13 1/7] target/arm/tcg: increase cache level for cpu=max

This patch addresses cache description in the `aarch64_max_tcg_initfn` function for cpu=max. It introduces three layers of caches and modifies the cache description registers accordingly. Reviewed-by: Jonathan Cameron Signed-off-by: Alireza Sanaee --- target/arm/tcg/cpu64.c | 13 +

[PATCH v13 0/7] Specifying cache topology on ARM

Specifying the cache layout in virtual machines is useful for applications and operating systems to fetch accurate information about the cache structure and make appropriate adjustments. Enforcing correct sharing information can lead to better optimizations. Patches that allow for an interface to e
