This array is currently statically defined (see ./drivers/acpi/tables.c). When there are more table entries than can be held in the 'initial_tables[]' array, the message "Truncating N table entries!" is output. As currently implemented, this message will always erroneously calculate N as 0. This patch fixes the calculation that determines how many table entries will be missing (truncated). This modification may be used under either the GPL or the BSD-style license used for Intel ACPI CA code.

This can also be seen in commit 8b59560a3baf2e7c24e0fb92ea5d09eca92805db (ACPI: dock: avoid check _STA method). If an undock is processed, the dock driver sends a uevent and userspace might read the show_docked property in sysfs. This causes an evaluation of _STA of the particular device which causes the dock driver to immediately dock again. In any case, evaluation of _STA (show_docked) does not necessarily mean that we are docked, so check with the internal device structure. http://bugzilla.kernel.org/show_bug.cgi?id=12360 Signed-off-by: Holger Macht <hmacht@suse.de> Signed-off-by: Len Brown <len.brown@intel.com>

| | * ACPI: remove BM_RLD access from idle entry pathLen Brown2009-01-291-48/+9

This is contrary to the erroneous wording the ACPI 2.0, 3.0 specifications that suggests that BM_RLD is an indicator rather than a control bit. ACPI 1.0's correct wording should be restored in ACPI 4.0: http://www.acpica.org/bugzilla/show_bug.cgi?id=689 But the kernel should not have to clear BM_RLD when entering a non C3-type state just to set it again when entering a C3-type C-state. We should be able to set BM_RLD at boot time and leave it alone -- removing the overhead of accessing this IO register from the idle entry path. Signed-off-by: Len Brown <len.brown@intel.com>
| | * ACPI: remove locking from PM1x_STS register readsLen Brown2009-01-281-2/+2
| |/ |/| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | PM1a_STS and PM1b_STS are twins that get OR'd together on reads, and all writes are repeated to both. The fields in PM1x_STS are single bits only, there are no multi-bit fields. So it is not necessary to lock PM1x_STS reads against writes because it is impossible to read an intermediate value of a single bit. It will either be 0 or 1, even if a write is in progress during the read. Reads are asynchronous to writes no matter if a lock is used or not. Signed-off-by: Len Brown <len.brown@intel.com>
| * ACPI: Skip the first two elements in the _BCL packageZhao Yakui2009-02-031-4/+4
|/ | | | | | | | | | | | | | | | | | | | | | According to the Spec the first two elements in the _BCL package won't be regarded as the available brightness level. The first is the brightness when full power is connected to the box(It means that the AC adapter is plugged). The second is the brightness level when the box is on battery. If the first two elements are still used while finding the next brightness level, it will fall back to the lowest level when keeping on pressing hotkey. (On some boxes the brightness will be changed twice when hotkey is pressed once. One is in the ACPI video driver. The other is changed by sys I/F. In the ACPI video driver the first two elements will be used while changing the brightness. But the first two elements is skipped while using sys I/F. In such case there exists the inconsistency). So he first two elements had better be skipped while showing the available brightness or finding the next brightness level. http://bugzilla.kernel.org/show_bug.cgi?id=12450 Signed-off-by: Zhao Yakui <yakui.zhao@intel.com> Signed-off-by: Len Brown <len.brown@intel.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch changes pci_irq.c to always use PCI INTx pin encodings instead of a mix of PCI and _PRT encodings. The PCI INTx pin numbers from the PCI_INTERRUPT_PIN config register are 0=device doesn't use interrupts, 1=INTA, ..., 4=INTD. But the _PRT table uses 0=INTA, ..., 3=INTD. This patch converts the _PRT encoding to the PCI encoding immediately when we add a _PRT entry to the global list. All the rest of the code can then use the PCI encoding consistently. The point of this is to make the interrupt swizzling look the same as on other architectures, so someday we can unify them.

| | * | | ACPI/PCI: PCI MSI _OSC support capabilities called when root bridge addedAndrew Patterson2009-01-071-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The _OSC capability OSC_MSI_SUPPORT is set when the root bridge is added with pci_acpi_osc_support(), so we no longer need to do it in the PCI MSI driver. Also adds the function pci_msi_enabled, which returns true if pci=nomsi is not on the kernel command-line.
