* x86: pre-initialize boot_cpu_data.x86_phys_bits to avoid system_state testsJeremy Fitzhardinge2009-03-05
| | | | | | | | | | | Impact: cleanup, micro-optimization Pre-initialize boot_cpu_data.x86_phys_bits to a reasonable default to remove the use of system_state tests in __virt_addr_valid() and __phys_addr().

| * x86: fix DMI on EFIBrian Maly2009-03-04
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Impact: reactivate DMI quirks on EFI hardware DMI tables are loaded by EFI, so the dmi calls must happen after efi_init() and not before. Currently Apple hardware uses DMI to determine the framebuffer mappings for efifb. Without DMI working you also have no video on MacBook Pro. This patch resolves the DMI issue for EFI hardware (DMI is now properly detected at boot), and additionally efifb now loads on Apple hardware (i.e. video works).

* | x86: refactor x86_quirks supportIngo Molnar2009-02-22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Impact: cleanup Make x86_quirks support more transparent. The highlevel methods are now named: extern void x86_quirk_pre_intr_init(void); extern void x86_quirk_intr_init(void); extern void x86_quirk_trap_init(void); extern void x86_quirk_pre_time_init(void); extern void x86_quirk_time_init(void); This makes it clear that if some platform extension has to do something here that it is considered ... weird, and is discouraged.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | With refactoring of wake_cpu macros the 32bit code in tip doesn't execute generic_apic_probe if CONFIG_X86_32_NON_STANDARD is not set. Even on a x86 STANDARD cpu we need to execute the generic_apic_probe function, as we rely on this function to execute the update_genapic quirk which initilizes apic->wakeup_cpu. Failing to do so results in we making a call to a null function in do_boot_cpu. The stack trace without the patch goes like this.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | x86/Voyager had this Kconfig quirk: config X86_FIND_SMP_CONFIG def_bool y depends on X86_MPPARSE || X86_VOYAGER Which splits off the find_smp_config() callback into a build-time quirk. Voyager should use the existing x86_quirks.mach_find_smp_config() callback to introduce SMP-config quirks. NUMAQ-32 and VISWS already use this. Signed-off-by: Ingo Molnar <mingo@elte.hu>
* | x86: generalize boot_cpu_idIngo Molnar2009-01-29
| | | | | | | | | | | | | | | | x86/Voyager can boot on non-zero processors. While that can probably be fixed by properly remapping the physical CPU IDs, keep boot_cpu_id for now for easier transition - and expand it to all of x86. Signed-off-by: Ingo Molnar <mingo@elte.hu>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The x86/Voyager subarch used to have this distinction between 'x86 SMP support' and 'Voyager SMP support': config X86_SMP bool depends on SMP && ((X86_32 && !X86_VOYAGER) || X86_64) This is a pointless distinction - Voyager can (and already does) use smp_ops to implement various SMP quirks it has - and it can be extended more to cover all the specialities of Voyager. So remove this complication in the Kconfig space. Signed-off-by: Ingo Molnar <mingo@elte.hu>

This avoids multiple calls to the hypervisor detection function. This patch adds function to detect if we are running under VMware. The current way to check if we are on VMware is following, # check if "hypervisor present bit" is set, if so read the 0x40000000 cpuid leaf and check for "VMwareVMware" signature. # if the above fails, check the DMI vendors name for "VMware" string if we find one we query the VMware hypervisor port to check if we are under VMware. The DMI + "VMware hypervisor port check" is needed for older VMware products, which don't implement the hypervisor signature cpuid leaf. Also note that since we are checking for the DMI signature the hypervisor port should never be accessed on native hardware. This patch also adds a hypervisor_get_tsc_freq function, instead of calibrating the frequency which can be error prone in virtualized environment, we ask the hypervisor for it. We get the frequency from the hypervisor by accessing the hypervisor port if we are running on VMware. Other hypervisors too can add code to the generic routine to get frequency on their platform.

The sparseirq branch is just preliminary groundwork: no sparse IRQs are actually implemented by this tree anymore - just the new APIs are added while keeping the old way intact as well (the new APIs map 1:1 to irq_desc[]). The 'real' sparse IRQ support will then be a relatively small patch ontop of this - with a v2.6.29 merge target. * 'genirq-v28-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/linux-2.6-tip: (178 commits) genirq: improve include files intr_remapping: fix typo io_apic: make irq_mis_count available on 64-bit too genirq: fix name space collisions of nr_irqs in arch/* genirq: fix name space collision of nr_irqs in autoprobe.c genirq: use iterators for irq_desc loops proc: fixup irq iterator genirq: add reverse iterator for irq_desc x86: move ack_bad_irq() to irq.c x86: unify show_interrupts() and proc helpers x86: cleanup show_interrupts genirq: cleanup the sparseirq modifications genirq: remove artifacts from sparseirq removal genirq: revert dynarray genirq: remove irq_to_desc_alloc genirq: remove sparse irq code genirq: use inline function for irq_to_desc genirq: consolidate nr_irqs and for_each_irq_desc() x86: remove sparse irq from Kconfig genirq: define nr_irqs for architectures with GENERIC_HARDIRQS=n ...
