[PATCH] uml: reuse i386 cpu-specific tuning Make UML share the underlying cpu-specific tuning done on i386. Actually, for now many config options aren't used a lot - but that can be done later. Also, UML relies on GCC optimization for things like memcpy and such more than i386, so specifying the correct -march and -mtune should be enough. Later, we may want to correct some other stuff. For instance, since FPU context switching, for us, is done (at least partially, i.e. between our kernelspace and userspace) by the host, we may allow usage of FPU operations by GCC. This doesn't hold for kernelspace vs. kernelspace, but we don't support preemption.

[PATCH] uml: reuse i386 cpu-specific tuning Make UML share the underlying cpu-specific tuning done on i386. Actually, for now many config options aren't used a lot - but that can be done later. Also, UML relies on GCC optimization for things like memcpy and such more than i386, so specifying the correct -march and -mtune should be enough. Later, we may want to correct some other stuff. For instance, since FPU context switching, for us, is done (at least partially, i.e. between our kernelspace and userspace) by the host, we may allow usage of FPU operations by GCC. This doesn't hold for kernelspace vs. kernelspace, but we don't support preemption.

[PATCH] i386: Add an option for the VIA C7 which sets appropriate L1 cache The VIA C7 is a 686 (with TSC) that supports MMX, SSE and SSE2, it also has a cache line length of 64 according to http://www.digit-life.com/articles2/cpu/rmma-via-c7.html. This patch sets gcc to -march=686 and select s the correct cache shift.

[PATCH] uml: reuse i386 cpu-specific tuning Make UML share the underlying cpu-specific tuning done on i386. Actually, for now many config options aren't used a lot - but that can be done later. Also, UML relies on GCC optimization for things like memcpy and such more than i386, so specifying the correct -march and -mtune should be enough. Later, we may want to correct some other stuff. For instance, since FPU context switching, for us, is done (at least partially, i.e. between our kernelspace and userspace) by the host, we may allow usage of FPU operations by GCC. This doesn't hold for kernelspace vs. kernelspace, but we don't support preemption.

x86: Eliminate redundant/contradicting cache line size config options Rather than having X86_L1_CACHE_BYTES and X86_L1_CACHE_SHIFT (with inconsistent defaults), just having the latter suffices as the former can be easily calculated from it. To be consistent, also change X86_INTERNODE_CACHE_BYTES to X86_INTERNODE_CACHE_SHIFT, and set it to 7 (128 bytes) for NUMA to account for last level cache line size (which here matters more than L1 cache line size). Finally, make sure the default value for X86_L1_CACHE_SHIFT, when X86_GENERIC is selected, is being seen before that for the individual CPU model options (other than on x86-64, where GENERIC_CPU is part of the choice construct, X86_GENERIC is a separate option on ix86).

It was set to 128 bytes due to some cacheline aliasing problems on older P4 systems, but those are many years old and we dont optimize for them anymore.

x86-32: Rework cache flush denied handler The cache flush denied error is an erratum on some AMD 486 clones. If an invd instruction is executed in userspace, the processor calls exception 19 (13 hex) instead of #GP (13 decimal). On cpus where XMM is not supported, redirect exception 19 to do_general_protection(). Also, remove die_if_kernel(), since this was the last user.

[PATCH] uml: reuse i386 cpu-specific tuning Make UML share the underlying cpu-specific tuning done on i386. Actually, for now many config options aren't used a lot - but that can be done later. Also, UML relies on GCC optimization for things like memcpy and such more than i386, so specifying the correct -march and -mtune should be enough. Later, we may want to correct some other stuff. For instance, since FPU context switching, for us, is done (at least partially, i.e. between our kernelspace and userspace) by the host, we may allow usage of FPU operations by GCC. This doesn't hold for kernelspace vs. kernelspace, but we don't support preemption.

x86: Optimize cmpxchg64() at build-time some more Try to avoid the 'alternates()' code when we can statically determine that cmpxchg8b is fine. We already have that CONFIG_x86_CMPXCHG64 (enabled by PAE support), and we could easily also enable it for some of the CPU cases. Note, this patch only adds CMPXCHG8B for the obvious Intel CPU's, not for others. (There was something really messy about cmpxchg8b and clone CPU's, so if you enable it on other CPUs later, do it carefully.) If we avoid that asm-alternative thing when we can assume the instruction exists, we'll generate less support crud, and we'll avoid the whole issue with that extra 'nop' for padding instruction sizes etc. LKML-Reference: <alpine.LFD.2.01.0909301743150.6996@localhost.localdomain> Signed-off-by: Ingo Molnar <mingo@elte.hu>

kconfig: rename CONFIG_EMBEDDED to CONFIG_EXPERT The meaning of CONFIG_EMBEDDED has long since been obsoleted; the option is used to configure any non-standard kernel with a much larger scope than only small devices. This patch renames the option to CONFIG_EXPERT in init/Kconfig and fixes references to the option throughout the kernel. A new CONFIG_EMBEDDED option is added that automatically selects CONFIG_EXPERT when enabled and can be used in the future to isolate options that should only be considered for embedded systems (RISC architectures, SLOB, etc). Calling the option "EXPERT" more accurately represents its intention: only expert users who understand the impact of the configuration changes they are making should enable it.

x86: configuration options to compile out x86 CPU support code This patch adds some configuration options that allow to compile out CPU vendor-specific code in x86 kernels (in arch/x86/kernel/cpu). The new configuration options are only visible when CONFIG_EMBEDDED is selected, as they are mostly interesting for space savings reasons. An example of size saving, on x86 with only Intel CPU support: text data bss dec hex filename 1125479 118760 212992 1457231 163c4f vmlinux.old 1121355 116536 212992 1450883 162383 vmlinux -4124 -2224 0 -6348 -18CC +/- However, I'm not exactly sure that the Kconfig wording is correct with regard to !64BIT / 64BIT.
