2009-03-16ACPI: remove doubled status checkingJiri Slaby
There was a misplaced status test (two consequent tests without a statement in between) in acpi_bus_init for ages. Remove it, since the function which should be checked (acpi_os_initialize1) has BUG_ONs on failure paths.

2009-02-21ACPI: remove CONFIG_ACPI_SYSTEMBjorn Helgaas
Remove CONFIG_ACPI_SYSTEM. It was always set the same as CONFIG_ACPI, and it had no menu label, so there was no way to set it to anything other than "y". Some things under CONFIG_ACPI_SYSTEM (acpi_irq_handled, acpi_os_gpe_count(), event_is_open, register_acpi_notifier(), etc.) are used unconditionally by the CA, the OSPM, and drivers, so we depend on them always being present.

2009-02-21battery: don't assume we are fully charged when not charging or dischargingRichard Hughes
On hardware like the T61 it can take a couple of seconds for the battery to start charging after the power is connected, and we incorrectly tell userspace that we are fully charged, and then go back to charging. Only mark a battery as fully charged when the preset charge matches either the last full charge, or the design charge. http://bugzilla.kernel.org/show_bug.cgi?id=12632 Signed-off-by: Richard Hughes <hughsient@gmail.com> Acked-by: Alexey Starikovskiy <astarikovskiy@suse.de> Acked-by: Henrique de Moraes Holschuh <hmh@hmh.eng.br> Signed-off-by: Len Brown <len.brown@intel.com>

2009-02-07ACPICA: Fix table entry truncation calculationMyron Stowe
During early boot, ACPI RSDT/XSDT table entries are gathered into the 'initial_tables[]' array. 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.

2009-02-06ACPI: dock: Don't eval _STA on every show_docked sysfs readHolger Macht
Some devices trigger a DEVICE_CHECK on every evalutation of _STA. 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>
2009-02-06ACPI: disable ACPI cleanly when bad RSDP foundLen Brown
When ACPI is disabled in the BIOS of this VIA C3 box, it invalidates the RSDP, which Linux notices: ACPI Error (tbxfroot-0218): A valid RSDP was not found [20080926] Bug Linux neglected to disable ACPI at that stage, and later scribbled on smp_found_config: ACPI: No APIC-table, disabling MPS But this box doesn't run well in legacy PIC mode, it needed IOAPIC mode to perform correctly: http://lkml.org/lkml/2009/2/5/39 So exit ACPI mode cleanly when we first detect that it is hopeless.

2009-02-02ACPI: Skip the first two elements in the _BCL packageZhao Yakui
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>
2009-01-28ACPI: remove BM_RLD access from idle entry pathLen Brown
It is true that BM_RLD needs to be set to enable bus master activity to wake an older chipset (eg PIIX4) from C3. 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>
2009-01-28ACPI: remove locking from PM1x_STS register readsLen Brown
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>
