| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

Untangle this namespace spaghetti by setting ->acpi_madt_oem_check() to NULL on those subarchitectures that have no detection quirks, and rename the other ones (summit, es7000) that do. Also change default_acpi_madt_oem_check() to handle NULL entries, and clean its control flow up as well. Signed-off-by: Ingo Molnar <mingo@elte.hu>

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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

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.

And it is used to check whether the Cx type is supported or not. On some boxes the following Cx state package is obtained from _CST object: >{ ResourceTemplate () { Register (FFixedHW, 0x01, // Bit Width 0x02, // Bit Offset 0x0000000000889759, // Address 0x03, // Access Size ) }, 0x03, 0xF5, 0x015E } In such case we should use the bit[7:4] of Cx address to check whether the Cx type is supported or not. mask the MWAIT hint to avoid array address overflow Signed-off-by: Zhao Yakui <yakui.zhao@intel.com> Acked-by:Venki Pallipadi <venkatesh.pallipadi@intel.com> Signed-off-by: Len Brown <len.brown@intel.com>
* | | ACPI: disable MPS when NO APIC-table foundLen Brown2008-12-231-0/+11
|/ / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When ACPI is asked to find an MADT (APIC table) and fails, then ACPI expects to run in PIC mode. However, if an MP Table is was found, IRQs will be registered as if an IOAPIC is being used, even though ACPI is configuring interrupt links links for PIC mode. In this scenario, disable MPS so that IRQs are registered in PIC mode, consistent with ACPI. http://bugzilla.kernel.org/show_bug.cgi?id=12257 Signed-off-by: Len Brown <len.brown@intel.com>
* | ACPI: pci_link: remove acpi_irq_balance_set() interfaceBjorn Helgaas2008-11-111-1/+0
|/ | | | | | | | | | | | | | | | | | | This removes the acpi_irq_balance_set() interface from the PCI interrupt link driver. x86 used acpi_irq_balance_set() to tell the PCI interrupt link driver to configure links to minimize IRQ sharing. But the link driver can easily figure out whether to turn on IRQ balancing based on the IRQ model (PIC/IOAPIC/etc), so we can get rid of that external interface. It's better for the driver to figure this out at init-time. If we set it externally via the x86 code, the interface reduces modularity, and we depend on the fact that acpi_process_madt() happens before we process the kernel command line.

For further information, see http://bugzilla.kernel.org/show_bug.cgi?id=11516 Instead of removing the related dmi-quirks completely we'd like to keep them for (at least) one kernel version -- to double-check whether the early-quirks really took effect. But the dmi-quirks need to be called after early-quirks are executed. With this patch calling sequence for dmi-quriks is changed as follows: acpi_boot_table_init() (dmi-quirks) ... early_quirks() (detect bogus IRQ0 override) ... acpi_boot_init() (late dmi-quirks and setup IO APIC) Note: Plan is to remove the "late dmi-quirks" with next kernel version.

This breaks resume from suspend to RAM on x86_64 UP systems using SMP kernels, because this part of head_64.S is also executed during the resume and the invalid GDT address causes the system to crash. It doesn't break on 'true' SMP systems, because early_gdt_descr.address is modified every time native_cpu_up() runs. However, during resume it should point to the GDT of the boot CPU rather than to another CPU's GDT. For this reason, during suspend to RAM always make early_gdt_descr.address point to the boot CPU's GDT. This fixes http://bugzilla.kernel.org/show_bug.cgi?id=11568, which is a regression from 2.6.26.
