* x86_64: Early segment setup for VTZachary Amsden2007-08-111-0/+7
| | | | | | | | | | | | | | | | VT is very picky about when it can enter execution. Get all segments setup and get LDT and TR into valid state to allow VT execution under VMware and KVM (untested). This makes the boot decompression run under VT, which makes it several orders of magnitude faster on 64-bit Intel hardware. Before, I was seeing times up to a minute or more to decompress a 1.3MB kernel on a very fast box.

* [PATCH] x86: add command line length to boot protocolBernhard Walle2007-05-021-1/+6
| | | | | | | | | | | | | | | | | | | | | | Because the command line is increased to 2048 characters after 2.6.21, it's not possible for boot loaders and userspace tools to determine the length of the command line the kernel can understand. The benefit of knowing the length is that users can be warned if the command line size is too long which prevents surprise if things don't work after bootup. This patch updates the boot protocol to contain a field called "cmdline_size" that contain the length of the command line (excluding the terminating zero). The patch also adds missing fields (of protocol version 2.05) to the x86_64 setup code.

* [PATCH] x86-64: Move cpu verification code to common fileVivek Goyal2007-05-022-60/+24
| | | | | | | | | | | | | | | | | | | o This patch moves the code to verify long mode and SSE to a common file. This code is now shared by trampoline.S, wakeup.S, boot/setup.S and boot/compressed/head.S o So far we used to do very limited check in trampoline.S, wakeup.S and in 32bit entry point. Now all the entry paths are forced to do the exhaustive check, including SSE because verify_cpu is shared. o I am keeping this patch as last in the x86 relocatable series because previous patches have got quite some amount of testing done and don't want to distrub that. So that if there is problem introduced by this patch, at least it can be easily isolated. Signed-off-by: Eric W.

| | | | | | | | | | | | | | | | | | | | o X86_64 kernel should run from 2MB aligned address for two reasons. - Performance. - For relocatable kernels, page tables are updated based on difference between compile time address and load time physical address. This difference should be multiple of 2MB as kernel text and data is mapped using 2MB pages and PMD should be pointing to a 2MB aligned address. Life is simpler if both compile time and load time kernel addresses are 2MB aligned. o Flag the error at compile time if one is trying to build a kernel which does not meet alignment restrictions.

* [PATCH] x86-64: Relocatable Kernel SupportVivek Goyal2007-05-025-216/+418
| | | | | | | | | | | | | | | | | | | | | | This patch modifies the x86_64 kernel so that it can be loaded and run at any 2M aligned address, below 512G. The technique used is to compile the decompressor with -fPIC and modify it so the decompressor is fully relocatable. For the main kernel the page tables are modified so the kernel remains at the same virtual address. In addition a variable phys_base is kept that holds the physical address the kernel is loaded at. __pa_symbol is modified to add that when we take the address of a kernel symbol. When loaded with a normal bootloader the decompressor will decompress the kernel to 2M and it will run there. This both ensures the relocation code is always working, and makes it easier to use 2M pages for the kernel and the cpu. AK: changed to not make RELOCATABLE default in Kconfig Signed-off-by: Eric W.

* [PATCH] x86-64: shorten the x86_64 boot setup GDT to what the comment saysSteven Rostedt2006-11-141-3/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | Stephen Tweedie, Herbert Xu, and myself have been struggling with a very nasty bug in Xen. But it also pointed out a small bug in the x86_64 kernel boot setup. The GDT limit being setup by the initial bzImage code when entering into protected mode is way too big. The comment by the code states that the size of the GDT is 2048, but the actual size being set up is much bigger (32768). This happens simply because of one extra '0'. Instead of setting up a 0x800 size, 0x8000 is set up. On bare metal this is fine because the CPU wont load any segments unless they are explicitly used. But unfortunately, this breaks Xen on vmx FV, since it (for now) blindly loads all the segments into the VMCS if they are less than the gdt limit. Since the real mode segments are around 0x3000, we are getting junk into the VMCS and that later causes an exception. Stephen Tweedie has written up a patch to fix the Xen side and will be submitting that to those folks. But that doesn't excuse the GDT limit being a magnitude too big.

| | | | | | | | | | | | | | | | When compiling a 64-bit kernel on an Ubuntu 6.06 32bit system (whose GCC is also a cross-compiler for x86_64) I've seen that head.o is compiled as a 64-bit file (while it should not) and ld complaining about this during linking: [AK: it happens on all systems with new binutils] ld: warning: i386:x86-64 architecture of input file `arch/x86_64/boot/compressed/head.o' is incompatible with i386 output I've verified that removing -m64 from compilation flags to turn "-m64 -traditional -m32" into "-traditional -m32" fixes the issue.

| | | | | | | | | | | | | | | | | | Bugzilla #6552 says: "In arch/i386/boot/setup.S, movw is used instead of movb for PS/2 mouse information, although it is unsigned char. This does not harm, because the jmp instruction overwritten by movw is used before executing movw, and never be used again" I've no idea if this is a real bug or how it gets fixed, so I'm submitting it for review instead of letting it die of boredom in bugzilla. Aditionally to i386, I've changed x86-64, which mirrors the same code. Credits to Yoshinori K. Okuji, who found the problem and suggested a fix.

* [PATCH] x86_64: coding style and whitespace fixupsDomen Puncer2005-06-255-12/+9
| | | | | | | | | | | Remove some of the unnecessary differences between arch/i386 and arch/x86_64. This patch fixes more whitespace issues, some miscellaneous typos, a wrong URL and a factually incorrect statement about the current boot sector code.

* [PATCH] kexec: x86_64: add CONFIG_PHYSICAL_STARTEric W. Biederman2005-06-252-6/+8
| | | | | | | | | | | | | | | | | | | For one kernel to report a crash another kernel has created we need to have 2 kernels loaded simultaneously in memory. To accomplish this the two kernels need to built to run at different physical addresses. This patch adds the CONFIG_PHYSICAL_START option to the x86_64 kernel so we can do just that. You need to know what you are doing and the ramifications are before changing this value, and most users won't care so I have made it depend on CONFIG_EMBEDDED bzImage kernels will work and run at a different address when compiled with this option but they will still load at 1MB. If you need a kernel loaded at a different address as well you need to boot a vmlinux.

* [PATCH] use ${CROSS_COMPILE}installkernel in arch/*/boot/install.shIan Campbell2005-06-231-2/+2
| | | | | | | | | | | | | | | | | | | | | | | The attached patch causes the various arch specific install.sh scripts to look for ${CROSS_COMPILE}installkernel rather than just installkernel (in both /sbin/ and ~/bin/ where the script already did this). This allows you to have e.g. arm-linux-installkernel as a handy way to install on your cross target. It also prevents the script picking up on the host /sbin/installkernel which causes the script to fall through and do the install itself (which is what I actually use myself, with $INSTALL_PATH set). I don't believe it causes back-compatibility problems since calling the host installkernel was never likely to work or be what you wanted when cross compiling anyway. If $CROSS_COMPILE isn't set then nothing changes. I only use ARM and i386 myself but I figured it couldn't hurt to do the whole lot. I've cc'd those who I hope are the arch maintainers for files that I've touched.
