2013-05-29x86: Increase precision of x86_platform.get/set_wallclock()David Vrabel1-2/+2
All the virtualized platforms (KVM, lguest and Xen) have persistent wallclocks that have more than one second of precision. read_persistent_wallclock() and update_persistent_wallclock() allow for nanosecond precision but their implementation on x86 with x86_platform.get/set_wallclock() only allows for one second precision. This means guests may see a wallclock time that is off by up to 1 second. Make set_wallclock() and get_wallclock() take a struct timespec parameter (which allows for nanosecond precision) so KVM and Xen guests may start with a more accurate wallclock time and a Xen dom0 can maintain a more accurate wallclock for guests.

2013-04-10x86, mm: Patch out arch_flush_lazy_mmu_mode() when running on bare metalBoris Ostrovsky1-0/+1
Invoking arch_flush_lazy_mmu_mode() results in calls to preempt_enable()/disable() which may have performance impact. Since lazy MMU is not used on bare metal we can patch away arch_flush_lazy_mmu_mode() so that it is never called in such environment. [ hpa: the previous patch "Fix vmalloc_fault oops during lazy MMU updates" may cause a minor performance regression on bare metal. This patch resolves that performance regression.

2011-07-22lguest: use a special 1:1 linear pagetable mode until first switch.Rusty Russell1-6/+5
The Host used to create some page tables for the Guest to use at the top of Guest memory; it would then tell the Guest where this was. In particular, it created linear mappings for 0 and 0xC0000000 addresses because lguest used to switch to its real page tables quite late in boot. However, since d50d8fe19 Linux initialized boot page tables in head_32.S even before the "are we lguest?" boot jump. So, now we can simplify things: the Host pagetable code assumes 1:1 linear mapping until it first calls the LHCALL_NEW_PGTABLE hypercall, which we now do before we reach C code. This also means that the Host doesn't need to know anything about the Guest's PAGE_OFFSET. (Non-Linux guests might not even have such a thing). Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
2011-05-30lguest: fix timer interrupt setupRusty Russell1-0/+1

2010-12-16lguest: populate initial_page_tableRusty Russell1-3/+0
Two x86 patches broke lguest: 1) v2.6.35-492-g72d7c3b, which changed x86 to use the memblock allocator. In lguest, the host places linear page tables at the top of mem, which used to be enough to get us up to the swapper_pg_dir page tables. With the first patch, the direct mapping tables used that memory: Before: kernel direct mapping tables up to 4000000 @ 7000-1a000 After: kernel direct mapping tables up to 4000000 @ 3fed000-4000000 I initially fixed this by lying about the amount of memory we had, so the kernel wouldn't blatt the lguest boot pagetables (yuk!), but then... 2) v2.6.36-rc8-54-gb40827f, which made x86 boot use initial_page_table. This was initialized in a part of head_32.S which isn't executed by lguest; it is then copied into swapper_pg_dir. So we have to initialize it; and anyway we switch to it before we blatt the old tables, so that fixes the previous damage as well. For the moment, I cut & pasted the code into lguest's boot code, but next merge window I will merge them.

2010-12-16lguest: restore boot speedRusty Russell1-4/+7
lguest is dumb and drops *all* the pagetables for set_pte (which is only used for kernel mapping manipulation, so it's OK without highmem). But it's used a lot in boot, too. As a guest optimization, we suppressed this flushing until the first page switch. Now we have initial_page_table, that happens much earlier, so extend the heuristic to wait until we switch to something other than the swapper_pg_dir or initial_page_table. As measured on my laptop under kvm, this dropped the time-to-mount-root from 48 seconds to 4.3 seconds. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>

2010-04-14lguest: stop using KVM hypercall mechanismRusty Russell1-31/+30
This is a partial revert of 4cd8b5e2a159 "lguest: use KVM hypercalls"; we revert to using (just as questionable but more reliable) int $15 for hypercalls. I didn't revert the register mapping, so we still use the same calling convention as kvm. KVM in more recent incarnations stopped injecting a fault when a guest tried to use the VMCALL instruction from ring 1, so lguest under kvm fails to make hypercalls. It was nice to share code with our KVM cousins, but this was overreach.

2010-03-15ACPI: delete the "acpi=ht" boot optionLen Brown1-1/+0
acpi=ht was important in 2003 -- before ACPI was universally deployed and enabled by default in the major Linux distributions. At that time, there were a fair number of people who or chose to, or needed to, run with acpi=off, yet also wanted access to Hyper-threading. Today we find that many invocations of "acpi=ht" are accidental, and thus is it possible that it is doing more harm than good. In 2.6.34, we warn on invocation of acpi=ht. In 2.6.35, we delete the boot option. Signed-off-by: Len Brown <len.brown@intel.com>
