2017-07-09	util/cacheinfo: Fix warning generated by clang	Pranith Kumar	1	-1/+1
	Clang generates the following warning on aarch64 host: CC util/cacheinfo.o /home/pranith/qemu/util/cacheinfo.c:121:48: warning: value size does not match register size specified by the constraint and modifier [-Wasm-operand-widths] asm volatile("mrs\t%0, ctr_el0" : "=r"(ctr)); ^ /home/pranith/qemu/util/cacheinfo.c:121:28: note: use constraint modifier "w" asm volatile("mrs\t%0, ctr_el0" : "=r"(ctr)); ^~ %w0 Constraint modifier 'w' is not (yet?) accepted by gcc. Fix this by increasing the ctr size. Tested-by: Emilio G. Cota <cota@braap.org> Reviewed-by: Emilio G.

2017-06-19	util: add cacheinfo	Emilio G. Cota	1	-0/+185
	Add helpers to gather cache info from the host at init-time. For now, only export the host's I/D cache line sizes, which we will use to improve cache locality to avoid false sharing.
