[LLVMdev] Spilling register and frame indices
...ackSlot 3. At later stage, frame indices are replaced by calling to MRegisterInfo::eliminateFrameIndex. This works for me, but there's slight problem. The target does not have "register + contant" addressing mode, so accessing frame index should be done like this: some_register = frame_pointer + offset ...... [some_register] Since frame index eliminations happens after register allocation, I must make sure 'some_register' does not participate in normal register allocation. That approach sounds suboptimal. By "reserving" one register we can already cause som...

ftrace_enabled set to 1 on bootup, slow downs with CONFIG_FUNCTION_TRACER in virt environments?
Hey, I was running some benchmarks (netserver/netperf) where the init script just launched the netserver and nothing else and was concerned to see the performance not up to par. This was an HVM guest running with PV drivers. If I compile the kernel without CONFIG_FUNCTION_TRACER it is much better - but it was my understanding that the tracing code does not impact the machine unless it is

Re: Debugging Xen via serial console
Hi, kdb: to debug xen hypervisor, could also debug guests gdbsx: to debug PV/HVM linux guests The tree is : http://xenbits.xensource.com/ext/debuggers.hg See README-dbg. You''ll need to setup serial access for kdb. Thanks, Mukesh > > Hi Dan, > > I''m currently using your version of ssplitd as it is. I haven''t tried > kdb. For some reason I

[PATCH RFC 0/8] xen/arm: initial cubieboard2 support.
See http://www.gossamer-threads.com/lists/xen/devel/297170 for some information on how to get this going. I''ve rebased and addressed the review comments. As before several of the patches are not to be applied because they can be done better using infrastructure from Julien''s "Allow Xen to boot with a raw Device Tree" patch. They are included for completeness. With

[PATCH v3 0/7] support for cubieboard2 / sunxi processors
See http://www.gossamer-threads.com/lists/xen/devel/297170 for some information on how to get this going. I''ve rebased and addressed the review comments. With this rebase I''ve picked up some patches from Julien which were required to do things properly, so the gic v7 and device blacklisting patches have been changed to use the proper mechanisms. Previously I was able to boot
