* acpi: fix buffer overrun on migrationMichael S. Tsirkin2015-11-191-2/+6
| | | | | | | | | | | | | | | | | ich calls acpi_gpe_init with length ICH9_PMIO_GPE0_LEN so ICH9_PMIO_GPE0_LEN/2 bytes are allocated, but then the full ICH9_PMIO_GPE0_LEN bytes are migrated. As a quick work-around, allocate twice the memory. We'll probably want to tweak code to avoid migrating the extra ICH9_PMIO_GPE0_LEN/2 bytes, but that is a bit trickier to do without breaking migration compatibility.

* hw/acpi: move "etc/system-states" fw_cfg file from PIIX4 to coreLaszlo Ersek2015-06-041-0/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | The acpi_pm1_cnt_init() core function is responsible for setting up the register block that will ultimately react to S3 and S4 requests (see acpi_pm1_cnt_write()). It makes sense to advertise this configuration to the guest firmware via an easy to parse fw_cfg file (ACPI is too complex for firmware to parse), and indeed PIIX4 does that. However, since acpi_pm1_cnt_init() is not specific to PIIX4, neither should be the fw_cfg file. This patch makes "etc/system-states" appear on all chipsets modified in the previous patch, not just PIIX4 (assuming they have fw_cfg at all).

* hw/acpi: acpi_pm1_cnt_init(): take "disable_s3" and "disable_s4"Laszlo Ersek2015-06-041-1/+2
| | | | | | | | | | | | | | | | | | | This patch only modifies the function prototype and updates all chipset code that calls acpi_pm1_cnt_init() to pass in their own disable_s3 and disable_s4 settings. vt82c686 is assumed to be fixed "S3 and S4 enabled".

* | qemu: Adjust qemu wakeupLiu, Jinsong2013-09-251-1/+2
|/ | | | | | | | | | | | | | | | | | | | | | Currently Xen hvm s3 has a bug coming from the difference between qemu-traditioanl and qemu-xen. For qemu-traditional, the way to resume from hvm s3 is via 'xl trigger' command. However, for qemu-xen, the way to resume from hvm s3 inherited from standard qemu, i.e. via QMP, and it doesn't work under Xen. The root cause is, for qemu-xen, 'xl trigger' command didn't reset devices, while QMP didn't unpause hvm domain though they did qemu system reset. We have two qemu patches and one xl patch to fix Xen hvm s3 bug. This patch is the qemu patch 1. It adjusts qemu wakeup so that Xen s3 resume logic (which will be implemented at qemu patch 2) will be notified after qemu system reset.
