[PATCH 0/4][Xen-devel] update current microcode logic and add microcode S3 support
These patches are used to add microcode S3 support. However, current xen microcode logic has some issues, so before we add microcode S3 support, we update some current microcode logic. patch1/4: microcode-1-remove-redundant.patch X86 microcode: cancel redundant input parameter of microcode functions Cancel redundant input parameter ''uci'', since it can get from another input parameter ''cpu'' as index. patch2/4: microcode-2-update.patch X86 microcode: microcode logic update Update microcode logic: 1. separate microcode_fini_cpu() into 2 level to avoid deadlock (when fail at microcode_update_cpu); 2. cancel redundant collect_cpu_info at microcode.c level, use relative function at microcode driver level; 3. separate microcode_resume_cpu from microcode_update_cpu, because it''s redundant (should only be called when S3 wakeup) and will block newer microcode update when user update newer microcode.dat from user level; patch3/4: microcode-3-optimizing.patch X86 microcode: optimizing microcode update It''s possible the data file has multiple matching ucode, we needn''t to update multiple times, just keep searching the latest version, and update once. patch4/4: microcode-4-s3.patch X86 microcode: add S3 micorcode update When wakeup from S3, use per cpu microcode image to update cpu microcode.

RE: [PATCH 0/4][Xen-devel] update current microcode logic and add microcode S3 support
BTW, all microcode patches are rebased and tested on latest tree (xen c/s 19063, linux-2.6.18-xen.hg c/s 780) Thanks, Jinsong Liu, Jinsong wrote:> These patches are used to add microcode S3 support. > However, current xen microcode logic has some issues, so before we > add microcode S3 support, we update some current microcode logic. > > patch1/4: microcode-1-remove-redundant.patch > X86 microcode: cancel redundant input parameter of microcode functions > Cancel redundant input parameter ''uci'', since it can get from another > input parameter ''cpu'' as index. > > patch2/4: microcode-2-update.patch > X86 microcode: microcode logic update > Update microcode logic: > 1. separate microcode_fini_cpu() into 2 level to avoid deadlock (when > fail at microcode_update_cpu); > 2. cancel redundant collect_cpu_info at microcode.c level, use > relative function at microcode driver level; > 3. separate microcode_resume_cpu from microcode_update_cpu, because > it''s redundant (should only be called when S3 wakeup) and will block > newer microcode update when user update newer microcode.dat from user > level; > > patch3/4: microcode-3-optimizing.patch > X86 microcode: optimizing microcode update > It''s possible the data file has multiple matching ucode, we needn''t > to update multiple times, just keep searching the latest version, and > update once. > > patch4/4: microcode-4-s3.patch > X86 microcode: add S3 micorcode update > When wakeup from S3, use per cpu microcode image to update cpu > microcode. > > > Thanks, > Jinsong > _______________________________________________ > Xen-devel mailing list > Xen-devel@lists.xensource.com > http://lists.xensource.com/xen-devel_______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel
