[ I think this is a straight repost this patch, which addresses all the previous comments. I'd like to submit this for .24 as the basis for a unified paravirt_ops. Any objections? ] This patch refactors the paravirt_ops structure into groups of functionally related ops: pv_info - random info, rather than function entrypoints pv_init_ops - functions used at boot time (some for module_init

Here's a first attempt at splitting up paravirt_ops into more specific chunks. Its pretty clunky and chunky; mostly just a lot of replacement. The grouping of ops is very first cut; I'm open to suggestions about what groups should exist and what ops they each should contain. The only slightly subtle part is that I've kept the structures wrapped in a paravirt_ops structure,

Convert the hard-coded native patch assembly code strings to macros to facilitate sharing common code between 32-bit and 64-bit. These macros will also be used by a future patch which requires the GCC extended asm syntax of two '%' characters instead of one when specifying a register name.

In a future patch, the NATIVE_* instruction string macros will be used in GCC extended inline asm, which requires registers to have two '%' instead of one in the asm template string. Convert the DEF_NATIVE macro to the GCC extended asm syntax so the NATIVE_* macros can be shared more broadly. Signed-off-by: Josh Poimboeuf <jpoimboe at redhat.com> ---

Instead of using six globally visible paravirt ops structures combine them in a single structure, keeping the original structures as sub-structures. This avoids the need to assemble struct paravirt_patch_template at runtime on the stack each time apply_paravirt() is being called (i.e. when loading a module).

With removal of lguest some of the paravirt functions are no longer needed. Remove them.

Hi all, I've been working on a port of paravirt_ops for the x86_64 architectures for a couple of days. Here's the result so far. I'm posting it soon for early cooments. The more, the better. It's obviously based on the previous work for i386, with the needed modifications. By now, I'm able to boot a bare metal kernel, but there are still some known issues, that are in my TODO

There is a lot of infrastructure for functionality which is used exclusively in __{save,restore}_processor_state() on the suspend/resume path. cr8 is an alias of APIC_TASKPRI, and APIC_TASKPRI is saved/restored independently by lapic_{suspend,resume}(). Delete the saving and restoration of cr8, which allows for the removal of both PVOPS. Signed-off-by: Andrew Cooper <andrew.cooper3 at
