[PATCH 0/15] adjust pvops to accomodate its x86_64 variant

[PATCH 0/15] adjust pvops to accomodate its x86_64 variant

[Glauber de Oliveira Costa]

Hi folks,

With this series, the bulk of the work of pvops64 is done.
Here, I integrate most of the paravirt.c and paravirt.h files, making
them applicable to both architectures.

CONFIG_PARAVIRT is _not_ present yet. Basically, this code is missing page
table integration (patches currently being worked on by Jeremy).

Enjoy

[PATCH 01/15] change paravirt_32.c name

[Glauber de Oliveira Costa]

This patch changes paravirt_32.c to paravirt.c. The goal
is to have paravirt support in x86_64, so we do it in a common file

[PATCH 02/15] adjust PVOP_CALL/VCALL macros for x86_64

[Glauber de Oliveira Costa]

This patch adjust the PVOP_VCALL and PVOP_CALL macros to
work with x86_64. It has a different calling convention, and
we use auxiliary macros to account for both calling conventions
as cleanly as possible

Comments are adjusted accordingly.

[PATCH 03/15] cleanup write_tsc

[Glauber de Oliveira Costa]

write_tsc() does not need to be enclosed in any paravirt closure,
as it uses wrmsr(). So we rip off the duplicate in msr.h
and the definition from paravirt.h

[PATCH 03/15] cleanup write_tsc

[Glauber de Oliveira Costa]

write_tsc() does not need to be enclosed in any paravirt closure,
as it uses wrmsr(). So we rip off the duplicate in msr.h
and the definition from paravirt.h

[PATCH 05/15] change assembly definition of paravirt_patch_site

[Glauber de Oliveira Costa]

To account for differences in x86_64, we change the macros that
create raw instances of the paravirt_patch_site struct.
We need to align 64-pointers to 64-bit boundaries, so we add an alignment
directive. Also, we need to make room for a word-sized pointer,
instead of a fixed 32-bit one

[PATCH 07/15] change irq functions to accomodate x86_64

[Glauber de Oliveira Costa]

This patch changes the irq handling function definitions
in paravirt.h (like raw_local_irq_disable) to accomodate for x86_64.
The differences are in the calling convention.

[PATCH 08/15] add macro for privileged x86_64 operation

[Glauber de Oliveira Costa]

i386 has a macro GET_CR0_INTO_EAX, used in early trap handling code.
x86_64 has similar needs, only it needs to put cr2 into rcx. We provide
a macro for such task, in the same way

[PATCH 10/15] replace privileged instructions with paravirt macros

[Glauber de Oliveira Costa]

The assembly code in entry_64.S issues a bunch of privileged instructions,
like cli, sti, swapgs, and others. Paravirt guests are forbidden to do so,
and we then replace them with macros that will do the right thing.

[PATCH 11/15] cleanup CLI_STRING, STI_STRING and friends

[Glauber de Oliveira Costa]

Since the advent of ticket locking, CLI_STRING, STI_STRING, and friends
are not used anymore. They can now be safely deleted.

[PATCH 12/15] add CLBR_ defines for x86_64.

[Glauber de Oliveira Costa]

x86_64 needs a potentially larger clobber list than i386, due to its calling
convention. So we add more CLBR_ defines for it.
Note that CLBR_ANY is different for each of the architectures, since it comprises
the notion of "All call clobbers in this architecture"

this patch adds the paravirt_patch_32.o:

> -obj-$(CONFIG_PARAVIRT)		+= paravirt.o
> +obj-$(CONFIG_PARAVIRT)		+= paravirt.o paravirt_patch_32.o

but does not add that file nor any other rule to build that target, so 
it fails to build with the attached config:

make[1]: *** No rule to make target 
 `arch/x86/kernel/paravirt_patch_32.o', needed by 
 `arch/x86/kernel/built-in.o'.  Stop.

Re: [PATCH 13/15] move patching code to arch-specific file.

[Ingo Molnar]

[-- Attachment #1: Type: text/plain, Size: 578 bytes --]


* Glauber de Oliveira Costa <gcosta@redhat.com> wrote:

> The core patching code for paravirt is sufficiently different

this patch adds the paravirt_patch_32.o:

> -obj-$(CONFIG_PARAVIRT)		+= paravirt.o
> +obj-$(CONFIG_PARAVIRT)		+= paravirt.o paravirt_patch_32.o

but does not add that file nor any other rule to build that target, so 
it fails to build with the attached config:

make[1]: *** No rule to make target 
 `arch/x86/kernel/paravirt_patch_32.o', needed by 
 `arch/x86/kernel/built-in.o'.  Stop.

if it's just that single missing file then please send me a patch that 
adds that file and i'll add it to this patch. (instead of resending the

[PATCH 13/15] move patching code to arch-specific file.

[Glauber de Oliveira Costa]

The core patching code for paravirt is sufficiently different
among i386 and x86_64, and we move them to specific files.

[PATCH 10/15] replace privileged instructions with paravirt macros

[Glauber de Oliveira Costa]

The assembly code in entry_64.S issues a bunch of privileged instructions,
like cli, sti, swapgs, and others. Paravirt guests are forbidden to do so,
and we then replace them with macros that will do the right thing.

[PATCH 07/15] change irq functions to accomodate x86_64

[Glauber de Oliveira Costa]

This patch changes the irq handling function definitions
in paravirt.h (like raw_local_irq_disable) to accomodate for x86_64.
The differences are in the calling convention.

[PATCH 02/15] adjust PVOP_CALL/VCALL macros for x86_64

[Glauber de Oliveira Costa]

This patch adjust the PVOP_VCALL and PVOP_CALL macros to
work with x86_64. It has a different calling convention, and
we use auxiliary macros to account for both calling conventions
as cleanly as possible

Comments are adjusted accordingly.

[PATCH 01/15] change paravirt_32.c name

[Glauber de Oliveira Costa]

This patch changes paravirt_32.c to paravirt.c. The goal
is to have paravirt support in x86_64, so we do it in a common file
