* Power Management Update @ 2003-08-30 21:25 Patrick Mochel 2003-08-31 12:31 ` Felipe Alfaro Solana ` (3 more replies) 0 siblings, 4 replies; 14+ messages in thread From: Patrick Mochel @ 2003-08-30 21:25 UTC (permalink / raw) To: linux-kernel I'm pleased to announce the release of the first patchset of power management changes for 2.6.0. The purpose of this release is to give people a chance to review and test the PM code before it's sent on to Linus. These patches include a number of cleanups and fixes to the PM core code, the driver core PM code, and swsusp. I have verified that all suspend states (standby, suspend-to-ram, and suspend-to-disk) work on a number of personal systems using ACPI as the low-level power interface. However, this is with limited functionality (from a VGA console with minimal processes running). These patches should restore suspend functionality for those that were able to successfully do it before -test3 and -test4. My apologies for the inconvenience my previous changes caused. These patches will probably not allow any more people to suspend/resume than before. The net benefit of these, and the already committed ones, are a cleaner power management subsystem and the development of the proper framework for successfully suspending and resuming the entire system. There are still several rough edges, though we seem to be making headway on those relatively rapidly, and are my sole focus at the moment. My main concerns right now are: - Platform devices, and more generally, devices that may belong to more than one class. It's mainly a driver model problem, though it has PM implications that appear to be holding a few people up. - Drivers Drivers have always been the main impedence to having a working PM core, though it's been difficult to make a lot of progress. I have a number of devices that I will verify work properly, and be in contact with the maintainers if necessary. (Though, I seem to be having more problems with IRQ routing at the moment.) - Getting it work on more systems. Hopefully we will not run into any serious issues, though the PM code has traditionally been finicky. I have a wide array of test machines and willing testers, so this should move quickly. - APM I unfortunately have not had a chance to look into the reported APM problems. But, I'm happy to say that I finally dug out an old laptop that has APM on it. I should make traction soon. I encourage willing people to download the patch, test, and report any problems back to me and/or the list. I cannot guarantee definite or timely results for systems where PM simply doesn't work. However, the more systems we characterize, the easier this will become in the future. Please be patient. If you're using BitKeeper, you can pull the tree from: bk://kernel.bkbits.net:/home/mochel/linux-2.5-power Or, a GNU patch is available at: http://developer.osdl.org/~mochel/patches/test4-pm1/test4-pm1.diff.bz2 There are split patches for each BK revision in that directory.

Reinstated in the name of compatibility. - Restored original semantics - if software_suspend() is enabled, then just call that (and never go into low-power state). Otherwise, call acpi_suspend(). - acpi_suspend() is simply a wrapper for pm_suspend(), passing down the right argument. This is so we don't have to do everything manually anymore. - Fixed long-standing bug by checking for "4b" in string written in to determine if we want to enter S4bios. <mochel@osdl.org> (03/08/30 1.1300) [swsusp] Restore software_suspend() call. - Allows 'backdoor' interface to swsusp, as requested by Pavel. - Simply a wrapper to pm_suspend(), though guaranteeing that swsusp is used, and system is shutdown (and put into low-power state). - Call in sys_reboot() changed back to call to software_suspend(). <mochel@osdl.org> (03/08/30 1.1299) [swsusp] Use BIO interface when reading from swap. - bios are the preferred method for doing this type of stuff in 2.6. The __bread() uses bio's in the end anyway. - bios make it really easy to implement write functionality, so we are able to reset the swap signature immediately after checking it during resume. So, if something happens while resuming, we will still have valid swap to use. - Thanks to Jens for some help in getting it working several months ago. <mochel@osdl.org> (03/08/29 1.1298) [swsusp] Minor cleanups in read_suspend_image() - Make resume_bdev global to file, so we don't have to pass it around (we always use the same one, so it shouldn't make a difference). - Allocate cur in read_suspend_image(), since it's the only function that uses it. - Check all errors and make sure we free cur if any happen. - Make sure to return errors from the functions called, not our own. - Free the pagedir if we hit an error after we allocate it. <mochel@osdl.org> (03/08/27 1.1297) [acpi] Move register save closer to call to enter sleep state. - By moving acpi_{save,restore}_state_mem() into acpi_pm_enter(), implying after interrupts have been disabled and nothing else is running on the system, S3 is able to resume properly. <mochel@osdl.org> (03/08/27 1.1296) [power] Make sure devices get added to the PM lists before bus_add_device(). - Prevents ordering issues when drivers add more devices ->probe(). <mochel@osdl.org> (03/08/26 1.1295) [power] Separate suspend-to-disk from other suspend sequences. - Put in kernel/power/disk.c - Make compilation depend on CONFIG_SOFTWARE_SUSPEND (should probably be renamed to CONFIG_PM_STD or some such). <mochel@osdl.org> (03/08/25 1.1294) [power] Fix handling of pm_users. - Actually decrement on device_pm_release() - Call from device_pm_remove(). <mochel@osdl.org> (03/08/25 1.1292) [power] Fix device suspend handling - Handle -EAGAIN in device_suspend() properly: keep going, with error reset to 0. - Call dpm_resume() if we got a real error, instead of device_resume(), which would deadlock. <mochel@osdl.org> (03/08/22 1.1276.19.8) [power] swsusp Cleanups - do_magic() - Rename to swsusp_arch_suspend(). - Move declaration to swsusp.c - arch_prepare_suspend() - Return an int - Fix x86 version to return -EFAULT if cpu does not have pse, instead of calling panic(). - Call from swsusp_save(). - do_magic_suspend_1() - Move body to pm_suspend_disk() - Remove. - do_magic_suspend_2() - Rename to swsusp_suspend() - Move IRQ fiddling to suspend_save_image(), since that's the only call that needs it. - Return an int. - do_magic_resume_1() - Move body to pm_resume(). - Remove - do_magic_resume_2() - Rename to swsusp_resume(). - Return an int. - swsusp general - Remove unnecessary includes. - Remove suspend_pagedir_lock, since it was only used to disable IRQs. - Change swsusp_{suspend,resume} return an int, so pm_suspend_disk() knows if anything failed. <mochel@osdl.org> (03/08/22 1.1276.19.7) [power] Move i386-specific swsusp code to arch/i386/power/ <mochel@osdl.org> (03/08/22 1.1276.19.6) [power] Fix up sysfs state handling. <mochel@osdl.org> (03/08/22 1.1276.19.5) [power] Make sure console level is high when suspending. <mochel@osdl.org> (03/08/22 1.1276.20.1) [power] Fix sysfs state reporting. ^ permalink raw reply [flat|nested] 14+ messages in thread

I apologize for the delay in getting back to you - I wanted to test an actual fix, rather than just a work around. I encountered this problem by having an IDE CD-ROM, but not having the ide-cd drier compiled in. The patch below is from Benh, who wrote the IDE power managment handlers. He mentioned producing a cleaner patch, but this should at least fix the Oops. Please give it a try and report if it helps or not.

Definitely. I take it you have preempt enabled, right? Below is a patch that should fix the problem. The problem was due to the fact that I removed the kernel_fpu_end() call from kernel/power/swsusp.c::swsusp_suspend(). kernel_fpu_end() disables preempt, which causes any subsequent schedule() to trigger that BUG(). I apologize for this regression. The patch needs a bit more explanation, because I didn't simply replace the call. Doing so would be a layering violation of the structure of the code. kernel_fpu_end() is called by save_processor_state(), which is called by swsusp_arch_suspend(). We should be calling it from the same chain, and we shouldn't be calling a function from generic code that is defined on only two architectures. I modified swsusp_arch_suspend() to unconditionally call restore_processor_state() when exiting, which provides the same layering. However, it is still too late WRT to the other things that swsusp_suspend() was doing (resuming drivers and writing the image). Since those are unrelated to snapshotting memory, I divorced them from the function. swsusp_save() now is the function that is responsible for snapshoting memory, while swsusp_write() is responsible for writing the image, only. The resulting code is cleaner and more streamlined. It behaves as predicted locally. Please try it and report whether or not it works for you. Andrew, please apply this to -test4-mm5. I realize I said I would not touch swsusp any more, and this patch may become irrelevant in the future. But, it fixes a real bug now.

I don't have preempt enabled, so I thought that this patch wasn't concerning me, but I tried it anyway. Result is a definite regression. standby/S1 or mem/S3 make the kernel oops and hangs. Call strace: enter_state suspend_prepare enter_state state_store subsys_attr_store fill_write_buffer sysfs_write_file vfs_write sys_write sysenter_past_esp or acpi_system_write_sleep acpi_system_write_sleep vfs_write sys_write sysenter_past_esp (depending on whether I use /sys/power/state or /proc/acpi/sleep) Before the patch, S1 and S3 would have the screen blink and computer immediately resume to normal operation. Sometimes, S1 would actually standby (screen lit and hard disk spinning, though) waiting for a keypress. disk/S4 don't suspend anymore.

Based on your dmesg here: http://perso.nerim.net/~tudia/bug-reports/2.6.0-pre4-pm Your system does not support S3, so returning immediately would be the proper thing to do.

Gracious renames to make sure I can not orient in the code :-(. -/* do_magic() is implemented in arch/?/kernel/suspend_asm.S, and basically does: +/* swsusp_arch_suspend() is implemented in arch/?/power/swsusp.S, + and basically does: if (!resume) { - do_magic_suspend_1(); save_processor_state(); SAVE_REGISTERS - do_magic_suspend_2(); + swsusp_suspend(); return; } GO_TO_SWAPPER_PAGE_TABLES - do_magic_resume_1(); COPY_PAGES_BACK RESTORE_REGISTERS restore_processor_state(); - do_magic_resume_2(); + swsusp_resume(); */ do_magic_suspend_1() did disable interrupts, where do you disable them now? Did you test it with CONFIG_PREEMPT to hunt for "scheduling in atomic" bugs? Your new naming is even worse than my original (and that's quite an achievement). swsusp_write() does swsusp_arch_suspend(), which in turn calls swsusp_suspend() ^- and that does the writing. Ouch. do_magic_* was clearer than *that*. I do not see why you had to change to BIOs just now. Perhaps you should get it into stable state, first, and then adding more code to make it look 2.6-like is good idea? [Will add more comments after a test].

[S3 blanks screen but does not enter sleep, S4 On 4030cdt, I could not test S3 due to unrelated ACPI error. I tried to enter S4 -- its still in progress; you moved io into atomic session with your "cleanups", so I get about 10000 "scheduling in atomic" messages. It actually does suspend and resume, but drivers are in very bad state after that, and machine is about 20x slower than it should be (you have broken UHCI, this might be side effect; or it might be one of 1001 other things). You imported ton of untested crap into -test4. If you want power managment to get into working state, REVERT THAT CRAP! Pavel -- When do you have a heart between your knees?
