Huang, Ying authored
This patch adds basic runtime services support for EFI x86_64 system. The main file of the patch is the addition of efi_64.c for x86_64. This file is modeled after the EFI IA32 avatar. EFI runtime services initialization are implemented in efi_64.c. Some x86_64 specifics are worth noting here. On x86_64, parameters passed to EFI firmware services need to follow the EFI calling convention. For this purpose, a set of functions named efi_call<x> (<x> is the number of parameters) are implemented. EFI function calls are wrapped before calling the firmware service. The duplicated code between efi_32.c and efi_64.c is placed in efi.c to remove them from efi_32.c. Signed-off-by:

This patch unifies the set_tss_desc between i386 and x86_64, which can now have a common implementation. After the old functions are removed from desc_{32,64}.h, nothing important is left, and the files can be removed. Signed-off-by:Glauber de Oliveira Costa <gcosta@redhat.com> Signed-off-by:

This patch moves _set_gate and its users to desc.h. We can now use common code for x86_64 and i386. [ mingo@elte.hu: set_system_gate() fixes for nasty crashes. ] Signed-off-by:

Glauber de Oliveira Costa authored
With the types used to access descriptors in x86_64 and i386 now being the same, the code that effectively handles them can now be easily shared. This patch moves the paravirt part of desc_32.h into desc.h, and then, we get paravirt support in x86_64 for free. Signed-off-by:

This patch makes get_desc_base() receive a struct desc_struct, and then uses its internal fields to compute the base address. This is done at both i386 and x86_64, and then it is moved to common header Signed-off-by:

This patch changes the type of tls_array in x86_64 to a desc_struct. Now, both i386 and x86_64 tls_array have the same type, and code accessing it can be shared. Signed-off-by:

This patch unifies the non-paravirt part of desc_{32,64}.h into desc.h. Most of it, is simply common code, that is moved to the shared header. The only exception is the set_ldt_desc in desc_64.h, which is changed - included its name - to accomodate for the way the ldt is set up in i386. Also, constant definitions used in desc_32.h are moved to desc_defs.h Signed-off-by: -

This patch changes the write_gdt_entry function signature. Instead of the old "a" and "b" parameters, it now receives a pointer to a desc_struct, and the size of the entry being handled. This is because x86_64 can have some 16-byte entries as well as 8-byte ones. Signed-off-by:

this patch changes write_idt_entry signature. It now takes a gate_desc instead of the a and b parameters. It will allow it to be later unified between i386 and x86_64. Signed-off-by:

This patch unifies struct desc_ptr between i386 and x86_64. They can be expressed in the exact same way in C code, only having to change the name of one of them. As Xgt_desc_struct is ugly and big, this is the one that goes away. There's also a padding field in i386, but it is not really needed in the C structure definition. Signed-off-by:

Glauber de Oliveira Costa authored
This patch aims to make the access of struct desc_struct variables equal across architectures. In this patch, I unify the i386 and x86_64 versions under an anonymous union, keeping the way they are accessed untouched (a and b for 32-bit code, individual bit-fields for 64-bit). This solution is not beautiful, but will allow us to integrate common code that differed by the way descriptors were used. This is to be viewed incrementally. There's simply too much code to be fixed at once. In the future, goal is to set up in a single way of acessing the desc_struct fields. Signed-off-by:

This patch prepares the x86_64 architecture initialization for paravirt. It requires a memory initialization step, which is done by implementing 64-bit version for machine_specific_memory_setup, and putting an ARCH_SETUP hook, for guest-dependent initialization. This last step is done akin to i386 Signed-off-by:

We need something here because we can't call in and out instructions directly. However, we have to be careful, because no indirections are allowed in misc_64.c , and paravirt_ops is a kind of one. So just call it directly there Signed-off-by:

This patch add provisions for time related functions so they can be later replaced by paravirt versions. it basically encloses {g,s}et_wallclock inside the already existent functions update_persistent_clock and read_persistent_clock, and defines {s,g}et_wallclock to the core of such functions. it also allow for a later-on-game time initialization, as done by i386. Paravirt guests can set a function to do their own initialization this way. Signed-off-by: -

under paravirt, read cr2 cannot be issued directly anymore. So wrap it in a macro, defined to the operation itself in case paravirt is off, but to something else if we have paravirt in the game Signed-off-by:
