2019-05-07util/cacheinfo: Use uint64_t on LLP64 model to satisfy Windows ARM64Cao Jiaxi
Windows ARM64 uses LLP64 model, which breaks current assumptions.

2017-09-07configure: Drop AIX host supportPeter Maydell
Nobody has mentioned AIX host support on the mailing list for years, and we have no test systems for it so it is most likely broken. We've advertised in configure for two releases now that we plan to drop support for this host OS, and have had no complaints. Drop the AIX host support code. We can also drop the now-unused AIX version of sys_cache_info(). Note that the _CALL_AIX define used in the PPC tcg backend is also used for Linux PPC64, and so that code should not be removed.

2017-07-19util/cacheinfo: Add missing include for ppc linuxPhilippe Mathieu-Daudé
This include was forgotten when splitting cacheinfo.c out of tcg/ppc/tcg-target.inc.c (see commit b255b2c8). For a Centos7 host, the include path <signal.h> <bits/sigcontext.h> <asm/sigcontext.h> <asm/elf.h> <asm/auxvec.h> implicitly pulls in the desired AT_* defines. Not so for Debian Jessie.

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.

2017-06-19util: add cacheinfoEmilio G. Cota
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.
