* x86: Fix efi directory cleanupDaniel Kiper2013-05-071-2/+2
| | | | | | | | clean target is never called from xen/arch/x86/efi/Makefile. Move all needed stuff to xen/arch/x86/Makefile and additionally remove efi.lds. Signed-off-by: Daniel Kiper <daniel.kiper@oracle.com>
* x86: re-introduce map_domain_page() et alJan Beulich2013-01-231-0/+1
| | | | | | | | | | | | | | | | | | This is being done mostly in the form previously used on x86-32, utilizing the second L3 page table slot within the per-domain mapping area for those mappings. It remains to be determined whether that concept is really suitable, or whether instead re-implementing at least the non-global variant from scratch would be better. Also add the helpers {clear,copy}_domain_page() as well as initial uses of them. One question is whether, to exercise the non-trivial code paths, we shouldn't make the trivial shortcuts conditional upon NDEBUG being defined. See the debugging patch at the end of the series.

* x86: consolidate microcode loading codeJan Beulich2011-12-011-1/+2
| | | | | | | | | | | | | | | | | | | | | | - memory was leaked on a CPU offline/online cycle (including S3) - memory was leaked on AMD systems when microcode_update() ran a 2nd time with the same data that was used on the first run - microcode never got restored on APs during S3 resume (or post-boot onlining of a CPU that was also online when microcode_update() first ran [in the event the prior microcode update got lost intermediately, which supposedly shouldn't happen]); this will still be the case when no other online CPU has an identical signature (which however is now consistent with bringing up such a CPU the very first time) - resume was unimplemented in the AMD case - there was a race between microcode_update_cpu() and microcode_resume_cpu() This also moves vendor specific type declarations to the vendor source file and sets the stage for boot time microcode loading (i.e. without Dom0 involvement).

* x86-64: EFI boot codeJan Beulich2011-06-281-4/+61
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Besides introducing the relevant code paralleling parts of what is under xen/arch/x86/boot/, this adjusts the build logic so that with a single compilation two images (gzip-compressed ELF and EFI application) can get created. The EFI part of this depends on a new enough compiler (supposedly gcc 4.4.x and above, but so far only tested to work with 4.5.x) and a properly configured linker (must support the i386pep emulation). If either functionality is found to not be available, the EFI part of the build will simply be skipped. The patch adds all code to allow Xen and the (accordingly enabled) Dom0 kernel to boot, but doesn't allow Dom0 to make use of EFI runtime calls (this will be the subject of the next patch). Parts of the code were lifted from an earlier never published OS project of ours - whether respective license information needs to be added to the respective source file is unclear to me (I was told internally that adding a GPLv2 license header can be done if needed by the community). Open issues (not preventing this from being committed imo): The trampoline allocation and initialization isn't really nice. This is due to the trampoline needing to be placed at a fixed address, and hence making the trampoline relocatable would seem desirable here (as well as for BIOS-based booting, where the trampoline location needed to be adjusted a number of time already in the past, due to it colliding with firmware data). By excluding mem.S, edd.S, and video.S from copied trampoline (i.e. moving up wakeup.S? and making sure none of the symbols are used from EFI code), the effective trampoline size could at least be reduced. Should the mappings of [__XEN_VIRT_START, mbi.mem_upper) and [_end, __XEN_VIRT_START+BOOTSTRAP_MAP_BASE) be destroyed, despite non-EFI code also keeping them?

* x86/fpu: extract extended related code into xstate.h and xstate.cWei Huang2011-05-091-0/+1
| | | | | | | | | | Current extended code is mixing with FPU code in i387.c. As part of FPU code cleanup, this patch moves all extended state code into independent files. Not much semantic are changed and most function names are kept untouched, except for xsave() and xsaveopt(). These two functions are combined into a single function.

* xen: add "lto=y" option to build Xen with link-time optimizations.Tim Deegan2011-03-071-7/+21

Only tested for x86_64 Xen builds using Clang/LLVM bitcode; it should be possible to do the same with newer GCCs and GIMPLE.

* x86: merge final linking scriptsKeir Fraser2009-07-131-1/+1
| | | | | | | | | | | | | While unrelated to the previous four patches, I realized that the two scripts are nearly identical when coding those earlier patches, and this patch depends on them in order to apply cleanly. As an extra measure, it also adjusts the (unused) space freed at the end of the per-CPU area to include all alignment space needed before the first actual constituent of the .bss section (up to 7 pages on x86-64).

The 32-bit C code framework that this sets up can also be used for other stuff in future: * early cmdline parsing * relocating multiboot modules so they too are guaranteed accessible Its interaction with normal Xen start-of-day, and with the 16-bit assembly trampoline, needs a bit of thought.

* xen: Big changes to x86 start-of-day:kfraser@localhost.localdomain2007-05-101-8/+6
| | | | | | | | | | | | | | | | | | | | 1. x86/64 Xen now relocates itself to physical high memory. This is useful if we have devices that need very low memory, or if in future we want to grant a 1:1 mapping of low physical memory to a special 'native client domain'. 2. We now only map low 16MB RAM statically. All other RAM is mapped dynamically within the constraints of the e820 map. It is recommended never to map MMIO regions, and this change means that Xen now obeys this constraint. 3. The CPU bootup trampoline is now permanently installed at 0x90000. This is necessary prereq for CPU hotplug. 4. Start-of-day asm is generally cleaned up and diff between x86/32 and x86/64 is reduced. Signed-off-by: Keir Fraser <keir@xensource.com>

* Replace dom0_ops hypercall with three new hypercalls:kfraser@localhost.localdomain2006-08-251-1/+3
| | | | | | | | | | | | | | | | | | | | | | 1. platform_op -- used by dom0 kernel to perform actions on the hardware platform (e.g., MTRR access, microcode update, platform quirks, ...) 2. domctl -- used by management tools to control a specified domain 3. sysctl -- used by management tools for system-wide actions Benefits include more sensible factoring of actions to hypercalls. Also allows tool compatibility to be tracked separately from the dom0 kernel. The assumption is that it will be easier to replace libxenctrl, libxenguest and Xen as a matched set if the dom0 kernel does not need to be replaced too (e.g., because that would require vendor revalidation). From here on we hope to maintain dom0 kernel compatibility. This promise is not extended to tool compatibility beyond the existing guarantee that compatibility will not be broken within a three-level stable release [3.0.2, 3.0.3, etc.].
