| * | teach the side-effect free drivers about the partition they are dealing | deraadt | 2013-11-06 | 1 | -16/+13 | |
| | | | | | | | | by passing a start/length in the HIB_INIT op. Then rebase all hibernate-time block offsets to be relative to the start of that partition. This simplifies things a lot. ok mlarkin | |||||
| * | Errant assignment that snuck in long ago. Pointed out by deraadt@ |   mlarkin | 2013-11-06 | 1 | -3/+1 | |

| * | Change an #if 0 surrounding a debug printf into a DPRINTF instead. | mlarkin | 2013-11-05 | 1 | -4/+2 | |

| * | Provide more debugging aids when failing to read the packed image from disk | mlarkin | 2013-10-20 | 1 | -2/+3 | |
| | | | | | | | during hibernate resume. requested by deraadt | |||||
| * | DPRINTFs for various failure cases, disabled by default (uncomment | mlarkin | 2013-10-20 | 1 | -4/+16 | |
| | | | | | HIB_DEBUG to see these) | |||||
| * | Flush the cache after bouncing the inflate page to the piglet. | mlarkin | 2013-10-20 | 1 | -1/+5 | |
| | | | | | | Fixes resume time stream corruption seen on x230 with large (16GB) unhibernation | |||||
| * | Use a second inflate page for stream finalize, since it is possible | mlarkin | 2013-10-20 | 1 | -5/+7 | |
| | | | | | | | | | | (though unlikely) for the end of stream marker to overflow from one page. This should fix a few (but not all) spurious failure-to-hibernate errors. Also remove an unnecessary cache flush during deflate. ok deraadt | |||||
| * | Adds DPRINTF/DNPRINTF macros to hibernate, and adds invocation of said | mlarkin | 2013-10-03 | 1 | -33/+56 | |
| | | | | | | | | | macros in various places to assist in debugging "failure to hibernate" errors. Macros are disabled by default - Uncomment #define HIB_DEBUG if you want more verbose messages during hibernate. | |||||
| * | Print out the compressed image size during unhibernate, for diagnostic | mlarkin | 2013-09-29 | 1 | -3/+5 | |
| | | | | | | purposes and to give the user an idea as to how much is going to be read in. | |||||
| * | Work around stack smash protector getting confused because we switched | mlarkin | 2013-06-01 | 1 | -18/+22 | |
| | | | | | stacks by not returning (ever) from hibernate_unpack_image. | |||||
| * | Change return codes in various hibernate functions to be able to later | mlarkin | 2013-06-01 | 1 | -12/+21 | |
| | | | | | | | distinguish one failure path from another. Comment the same. Also removed some extraneous comments regarding pmap_activate. | |||||
| * | We need to halt the APs on MP hibernate resume or else they will be | mlarkin | 2013-05-31 | 1 | -1/+5 | |
| | | | | | | | | | | | | executing code possibly causing side effects during the image unpack operation. But before we can halt the APs, we need to complete their init (as they will be hatched but idling, possibly with interrupts off). Introduces MD function hibernate_quiesce_cpus to do this, called from the MI hibernate resume code. ok deraadt | |||||
| * | Make interrupt handling in hibernate resume MI by providing MD-specific | mlarkin | 2013-05-30 | 1 | -3/+3 | |
| | | | | | | | | functions to enable and disable interrupts, if needed. If a platform doesnt need interrupt handling in this way, the MD function can be a no-op. discussed with pirofti and deraadt | |||||
| * | Comment a KASSERT whose purpose wasn't immediately apparent | mlarkin | 2013-05-30 | 1 | -1/+3 | |
| | | ||||||
| * | Add a magic number to the head of the signature block. Check for magic | mlarkin | 2013-04-09 | 1 | -9/+51 | |
| | | | | | | | | | | | | | | | | | number match during signature block read during speculative unhibernate on boot. If the magic number matches but we have otherwise chosen to not unhibernate (due to kernel/memory mismatch), clear the signature block early to avoid accidentally trying to unhibernate on subsequent boots. This prevents accidental unhibernates and endless unhibernate/reboot cycles. Add a define for HIBERNATE_DEBUG for various debugging printfs (disabled by default). Finally, change some KASSERTs to warning printfs (they probably shouldn't have been KASSERTs in the first place). "looks good" deraadt@ | |||||

| | | | | | | | IO to the disk, DVACT_RESUME the controller back to normal operation. That allows us to do the full DVACT_POWERDOWN sequence afterwards. ok mlarkin | |||||
| * | increase the number of pages used to hold the chunk ordering map and change | mlarkin | 2013-01-17 | 1 | -9/+8 | |
| | | | | | | the index type from int to short. Allows amd64 to hibernate with up to 64GB phys memory | |||||

| * | Temporarily don't do RLE page encoding in hibernate to fix some unpacking | mlarkin | 2012-07-12 | 1 | -101/+12 | |
| | | | | | | corruption seen earlier. This makes hibernate much slower but seems to fix the corruption problems seen on all machines we've tested on. | |||||

| | | | | | | | | i/o will not mix with regular i/o so it can only be used in the hibernate path. ok deraadt@ mlarkin@ | |||||

| * | hibernate: fix lock/unlock mismatch |   ariane | 2012-04-12 | 1 | -2/+2 | |
| | | | | | | Unlock missed an 'f', which caused it to unlock the in-use pageqs, rather than the free pageqs as it was supposed to. | |||||
| * | Fix an integer math error when using the result of uvm_page_rle, and | mlarkin | 2012-03-26 | 1 | -13/+12 | |
| | | | | | | | | | | | at the same time increase said function's max RLE page count return value. Add hooks in the right places to call the hibernate suspend and resume routines, so that we can enable hibernation with a HIBERNATE option line in GENERIC and appropriate acpi.c goo. discussed on and off with deraadt@ over the past few months | |||||
