...rrently on Windows x86-64 the processor features are not detected because the inline assembly (which Visual C++ deprecated for x64) does not have an alternative that uses intrinsics. Later tests for x86-64 then only enable SSE2, leaving any more recent instruction set unused. The patch uses the __cpuid intrinsic that compile under 32-bit as well as 64-bit. I've only tested it with my own experimental project on Windows x64 but I see no potential issues for other platforms. A potential additional improvement would be to cause a compiler error when the GetCpuIDAndInfo does not compile to the in...

Its over 10 years old and aren't there free versions of more recent MSVCs available? Erik -- ---------------------------------------------------------------------- Erik de Castro Lopo

Hi all, The latest version of FLAC has been releases. See: https://xiph.org/flac/index.html https://xiph.org/flac/changelog.html The source tarball and Windows binaries are available (with md5 and sha256 checksums) at: http://downloads.xiph.org/releases/flac/ The source tarball is also available at: https://sourceforge.net/projects/flac/files/flac-src/ and similarly the

I have finally gotten off the pot and finished writing up my new CPUID/MSR driver, which contains support for registers that need arbitrary GPRs touched. For i386 vs x86-64 compatibility, both use an x86-64 register image (16 64-bit register fields); this allows 32-bit userspace to access the full 64-bit image if the kernel is 64 bits. Anyway, this presumably requires new paravirtualization

This patch cleans up some 80-odd warnings I was seeing when compiling the xenpci driver, all completely trivial. It also replaces the use of asm for calling cpuid with the __cpuid compiler intrinsic, and modifies calling code accordingly. I''m pretty sure my mailer going to mangle the inline patch (below) so I''m attaching the pristine version.
