[Qemu-devel] [PATCH 1/3] hw/acpi: acpi_pm1_cnt_init(): take "disable_s3" and "disable_s4"

[Laszlo Ersek]

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-devel] [PATCH 2/3] hw/acpi: move "etc/system-states" fw_cfg file from PIIX4 to core

[Laszlo Ersek]

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).

[Qemu-devel] [PATCH 3/3] hw/acpi: piix4_pm_init(): take fw_cfg object no more

[Laszlo Ersek]

This PIIX4 init function has no more reason to receive a pointer to the
FwCfg object. Remove the parameter from the prototype, and update callers.

As a result, the pc_init1() function no longer needs to save the return
value of pc_memory_init() and xen_load_linux(), which makes it more
similar to pc_memory_init().

The return type & value of pc_memory_init() and xen_load_linux() are not
changed themselves; maybe we'll need their return values sometime later.

Argh, mis-paste. Whoever picks this up (assuming the patches are good
enough), please replace the 2nd instance of pc_memory_init() with
pc_q35_init().

Thanks!
