[Qemu-devel] [PATCH v3 0/2] tcg: allocate TB structs preceding translate

[Emilio G. Cota]

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
