v2: https://lists.gnu.org/archive/html/qemu-devel/2017-06/msg01147.html
Changes from v2:
- Dropped the configure-time check. Instead, do this at init-time
as suggested by Richard.
- Added Pranith's R-b tag to the TCG patch.
- Added cache info query for Windows thanks to Geerd's help.
- Added cache info query for MacOS [ #ifdef __APPLE__ ] via sysctl. (Note:
I only tested the code on a standalone program, since I cannot install
QEMU's dependences on the MacOS machine I got access to)
- Use int instead of unsigned int for the line sizes. This allows
us to use ROUND_UP without having to cast to int (ROUND_UP negates
the alignment parameter)
Question: is it worth adding a paranoid check to make sure the linesizes
we obtain are a pow2? If there's a bug somewhere in the reporting,
we'll get in trouble due to ROUND_UP, which only works with pow2
parameters. A safer alternative is to use QEMU_ALIGN_UP, but it's slower.
This patchset applies cleanly on top of the current master (65dfad62a).
Thanks,
Emilio
