2009-11-24[CPUFREQ] Enable ACPI PDC handshake for VIA/Centaur CPUsHarald Welte
In commit 0de51088e6a82bc8413d3ca9e28bbca2788b5b53, we introduced the use of acpi-cpufreq on VIA/Centaur CPU's by removing a vendor check for VENDOR_INTEL. However, as it turns out, at least the Nano CPU's also need the PDC (processor driver capabilities) handshake in order to activate the methods required for acpi-cpufreq. Since arch_acpi_processor_init_pdc() contains another vendor check for Intel, the PDC is not initialized on VIA CPU's. The resulting behavior of a current mainline kernel on such systems is: acpi-cpufreq loads and it indicates CPU frequency changes. However, the CPU stays at a single frequency This trivial patch ensures that init_intel_pdc() is called on Intel and VIA/Centaur CPU's alike.

2009-10-16x86: Document linker script ASSERT() quirkIngo Molnar
Older binutils breaks if ASSERT() is used without a sink for the output.

2009-08-28ACPI, x86: expose some IO-APIC routines when CONFIG_ACPI=nFeng Tang
Some IO-APIC routines are ACPI specific now, but need to be exposed when CONFIG_ACPI=n for the benefit of SFI. Remove #ifdef ACPI around these routines: io_apic_get_unique_id(int ioapic, int apic_id); io_apic_get_version(int ioapic); io_apic_get_redir_entries(int ioapic); Move these routines from ACPI-specific boot.c to io_apic.c: uniq_ioapic_id(u8 id) mp_find_ioapic() mp_find_ioapic_pin() mp_register_ioapic() Also, since uniq_ioapic_id() is now no longer static, re-name it to io_apic_unique_id() for consistency with the other public io_apic routines. For simplicity, do not #ifdef the resulting code ACPI || SFI, thought that could be done in the future if it is important to optimize the !ACPI !SFI IO-APIC x86 kernel for size.

Cc: len.brown@intel.com At the time, the IOAPIC version number was deliberately not printed in the x86_64 code path. However, after the x86 and x86_64 files were merged, the net result is that the IOAPIC version is printed incorrectly in the x86_64 code path. The patch below provides a fix.

This is the same case even for NMI structure reporting. The Processor X2APIC Affinity structure provides the association between the X2APIC ID of a logical processor and the proximity domain to which the logical processor belongs.

As acpi_enter_sleep_state can fail, take this into account in do_suspend_lowlevel and don't return to the do_suspend_lowlevel's caller. This would break (currently) fpu status and preempt count. Technically, this means use `call' instead of `jmp' and `jmp' to the `resume_point' after the `call' (i.e. if acpi_enter_sleep_state returns=fails). `resume_point' will handle the restore of fpu and preempt count gracefully.

2009-02-09x86: add mp_find_ioapic_pinJeremy Fitzhardinge
Add mp_find_ioapic_pin() to find an IO APIC's specific pin from a GSI, and use this function within acpi/boot. Make it non-static so other code can use it too. Signed-off-by: Jeremy Fitzhardinge <jeremy.fitzhardinge@citrix.com>

2009-02-09acpi/x86: introduce __apci_map_table, v4Yinghai Lu
to prevent wrongly overwriting fixmap that still want to use. ACPI used to rely on low mappings being all linearly mapped and grew a habit: it never really unmapped certain kinds of tables after use. This can cause problems - for example the hypothetical case when some spurious access still references it. v2: remove prev_map and prev_size in __apci_map_table v3: let acpi_os_unmap_memory() call early_iounmap too, so remove extral calling to early_acpi_os_unmap_memory v4: fix typo in one acpi_get_table_with_size calling Signed-off-by: Yinghai Lu <yhlu.kernel@gmail.com> Acked-by: Len Brown <len.brown@intel.com> Signed-off-by: Ingo Molnar <mingo@elte.hu>
2009-02-09acpi: remove final __acpi_map_table mapping before setting ↵Jeremy Fitzhardinge
acpi_gbl_permanent_mmap On x86, __acpi_map_table uses early_ioremap() to create the mapping, replacing the previous mapping with a new one. Once enough of the kernel is up an running it switches to using normal ioremap(). At that point, we need to clean up the final mapping to avoid a warning from the early_ioremap subsystem. This can be removed after all the instances in the ACPI code are fixed that rely on early-ioremap's implicit overmapping of previously mapped tables.

2009-02-09x86: always explicitly map acpi memoryJeremy Fitzhardinge
Always map acpi tables, rather than assuming we can use the normal linear mapping to access the acpi tables. This is necessary in a virtual environment where the linear mappings are to pseudo-physical memory, but the acpi tables exist at a real physical address. It doesn't hurt to map in the normal non-virtual case, so just do it unconditionally.

2009-02-09x86: use early_ioremap in __acpi_map_tableJeremy Fitzhardinge
__acpi_map_table() effectively reimplements early_ioremap(). Rather than have that duplication, just implement it in terms of early_ioremap(). However, unlike early_ioremap(), __acpi_map_table() just maintains a single mapping which gets replaced each call, and has no corresponding unmap function. Implement this by just removing the previous mapping each time its called. Unfortunately, this will leave a stray mapping at the end.
