From 1071695f17daf050638e0bc550db647f8237c3bb Mon Sep 17 00:00:00 2001 From: David Brownell Date: Fri, 22 Feb 2008 21:54:24 -0800 Subject: ACPI: crosslink ACPI and "real" device nodes Add cross-links between ACPI device and "real" devices in sysfs, exposing otherwise-hidden interrelationships between the various device nodes for ACPI stuff. As a representative example, one hardware device is exposed as two logical devices (PNP and ACPI): .../pnp0/00:06/ .../LNXSYSTM:00/device:00/PNP0A03:00/device:15/PNP0B00:00/ The PNP device gets a "firmware_node" link pointing to the ACPI device, and is what a Linux device driver binds to. The ACPI device has instead a "physical_node" link pointing back to the PNP device. Other firmware frameworks, like OpenFirmware, could do the same thing to couple their firmware tables to the rest of the system. (Based on a patch from Zhang Rui. This version is modified to not depend on the patch makig ACPI initialize driver model wakeup flags.)

At the same time one of them is non-wake(runtime) device and the other are wake devices. In such case OSPM should call the _PSW object to disable the device's ability to wake the sleeping system in the boot phase. Otherwise there will be ACPI interrupt flood triggered by the GPE input. The _PSW object is depreciated in ACPI 3.0 and is replaced by _DSW. So it is necessary to call _DSW object first.

In this case, these operators created namespace nodes that were incorrectly left marked as permanent nodes instead of temporary nodes. This could cause a problem if there is race condition between an exiting control method and a running namespace walk. (Reported by Linn Crosetto). Fixed a problem where the CreateField and CreateXXXField operators would incorrectly allow duplicate names (the name of the field) with no exception generated.

Passing only the pnp_dev * reduces the possibility for error in the caller and removes the pnp_resource_table implementation detail from the interface. Even though pnp_init_resource_table() is exported, I did not export pnp_init_resources() because it is used only by the PNP core.

I split this out because it changes the behavior slightly: we used to check for conflicts only with earlier resources, e.g., we checked resource 2 against resources 0 and 1 but not against 3, 4, etc. Now we will check against all resources except 2. Since resources are assigned in ascending order, the old behavior was probably safe, but I don't like to depend on that ordering.

We need this because it is important to write ISAPNP configuration back to the same registers we read it from. For example, if we read valid regions from memory descriptors 0, 1, and 3, we'd better write them back to the same registers, without compressing them to descriptors 0, 1, and 2. This was previously guaranteed by using the index into the pnp_resource_table array as the ISAPNP config register index. However, I am removing those fixed-size arrays, so we need to save the ISAPNP register index elsewhere.

The switch to the ACPI backlight mode in the firmware is designed to be safe to use only as an one way trapdoor. One is not to force the firmware to switch back to "DOS/bootloader" mode except by rebooting. The mode switch itself is performed by calling any of the ACPI _BCL methods at least once. When in ACPI mode, the backlight firmware just issues (standard) events for the brightness up/down hot key presses along with the non-standard HKEY events which thinkpad-acpi traps, and doesn't touch the hardware. thinkpad-acpi will: 1. Place the ThinkPad firmware in ACPI backlight control mode if one is available 2. Suppress HKEY backlight change notifications by default to avoid double-reporting when ACPI video is loaded when the ThinkPad is in ACPI backlight control mode 3. Urge the user to load the ACPI video driver The user is free to use either the ACPI video driver to get the brightness key events, or to override the thinkpad-acpi default hotkey mask to get them from thinkpad-acpi as well (this will result in duplicate events if ACPI video is loaded, so let's hope distros won't screw this up). Provided userspace is sane, all should work (and *keep* working), which is more that can be said about the non-ACPI mode of the new Lenovo ThinkPad BIOSes when coupled to current userspace and X.org drivers. Full guidelines for backlight hot key reporting and use of the thinkpad-acpi backlight interface have been added to the documentation.

Unfortunately, this information has not filtered down everywhere it needs to, yet. Notably, old ibm-acpi documentation and most "thinkpad setup guides" will have wrong information on this area. Warn the local admin once whenever any of the following patterns are met: 1. Attempts to set hotkey mask to 0xffff (artifact from docs and config for the old ibm-acpi driver and behaviour). This mask makes no real-world sense; 2. Attempts to set hotkey mask to 0xffffffff, which means the user is trying to just have "everything work" without even reading the documentation, or that we need to get a bug report, because there is a new thinkpad out there with new exciting hot keys :-) 3. Attempts to set hotkey mask to 0xffffff, which is almost never the correct way to set up volume and brightness event reporting (and with the current state-of-the-art, it is known to never be right way to do it). The driver will perform any and all requested operations, though, regardless of any warnings. I hope these warnings can be removed one or two years from now.

The problem is that, at boot time acpi driver is checking for "idle=" boot option and not registering the acpi idle handler. But, when there is a CST changed callback (typically when switching AC <-> battery or suspend-resume) there are no checks for boot_option_idle_override and acpi idle handler tries to get installed with nasty side effects. With CPU_IDLE configured this issue causes results in a nasty oops on CST change callback and without CPU_IDLE there is no oops, but boot option of "idle=" gets ignored and acpi idle handler gets installed. Change the behavior to not do anything in acpi idle handler when there is a "idle=" boot option. Note that the problem is only there when "idle=" boot option is used.
