| * ACPI: fix early DSDT dmi check warnings on ia64Lin Ming2010-05-191-1/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | WARNING: at drivers/firmware/dmi_scan.c:423 dmi_matches+0x70/0x160() dmi check: not initialized yet. This is caused by commit aa2110c (ACPI: add boot option acpi=copy_dsdt to fix corrupt DSDT). DMI is not initialized yet in acpi_early_init on ia64. The DSDT DMI check table is x86 specific, so make it empty on other archs. And this fixes the warnings on ia64.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We have ported Rafael's major GPE changes (ACPI: Use GPE reference counting to support shared GPEs) into ACPICA code base. But the port and Rafael's original patch have some differences, so we made below patch to make linux GPE code consistent with ACPICA code base. Most changes are about comments and coding styles. Other noticeable changes are based on: Rafael: Reduce code duplication related to GPE lookup https://patchwork.kernel.org/patch/86237/ Rafael: Always use the same lock for GPE locking https://patchwork.kernel.org/patch/90471/ A new field gpe_count in struct acpi_gpe_block_info to record the number of individual GPEs in block.

| * ACPI: add boot option acpi=copy_dsdt to fix corrupt DSDTLin Ming2010-04-204-0/+46
| | | | | | | | | | | | | | | | | | | | | | | | | | Some BIOS on Toshiba machines corrupt the DSDT, so add a new boot option acpi=copy_dsdt to workaround it. Add warning message to ask users to use this option if corrupt DSDT detected. Also build a DMI blacklist to check it and automatically copy DSDT. https://bugzilla.kernel.org/show_bug.cgi?id=14679 Signed-off-by: Lin Ming <ming.m.lin@intel.com> Signed-off-by: Len Brown <len.brown@intel.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | Optionally copy the entire DSDT to local memory (instead of simply mapping it.) There are some BIOSs that corrupt or replace the original DSDT, creating the need for this option.

Introduce soc_mixer_control.platform_max value, which initially equals to chip maximum. The snd_soc_limit_volume function only modify the platform_max, all volsw_info call returns this as well. The .max value holds the chip default (maximum), and it is used for the inversion, if it is needed. Additional check in the volsw_info call has been added to check the validity of the platform_max in case, when custom macros used by codec drivers are not initializing it correctly.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | As well as allowing DAPM pins to be marked as ignoring suspend allow DAI links to be similarly marked. This is primarily intended for digital links between CODECs and non-CPU devices such as basebands in mobile phones and will suppress all suspend calls for the DAI link. It is likely that this will need to be revisited if used with devices which are part of the SoC CPU.

One of the most common examples is smartphone systems, which are normally designed to allow audio to be run between the baseband and the CODEC without passing through the CPU and so can suspend the CPU when on a voice call for additional power savings. Support such systems by providing an API snd_soc_dapm_ignore_suspend(). This can be used to mark DAPM endpoints as not being sensitive to system suspend. When the system is being suspended paths between endpoints which are marked as ignoring suspend will be kept active. Both source and sink must be marked, and there must already be an active path between the two endpoints prior to suspend. When paths are active over suspend the bias management will hold the device bias in the ON state. This is used to avoid suspending the CODEC while it is still in use.

Since the core moves us into D3 prior to initating the suspend all power checks during suspend will cause the widgets to be powered down. In order to ensure that widgets are powered up on resume set the card to D2 at the start of resume handling (ALSA API calls require D0 so we are still protected against userspace access).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The core will ensure that the device is in either STANDBY or OFF bias before suspending, restoring the bias in the driver is unneeded.
