[PATCH] acpi: fix irq 8 ressource conflict

by Gerd Hoffmann

Both hpet and rtc have irq 8 in their ressources, making windows unhappy because of the conflict. Fix this by making rtc check whenever the hpet is present, and claim irq 8 only in case it isn't. So rtc gets irq 8 only in case you start qemu with the -no-hpet switch. Verified working in both linux (check pnp boot messages) and windows (check rtc ressources in device manager) guests.

[PATCH] acpi: PCI routing DSDT simplifications.

by Kevin O'Connor

Use define_link() macro in PIIX4 hardware definitions. Now that all remaining irq links are the same it's possible to just use a macro to define the link. Port several size optimizations to the q35 irq routing definitions: define the PRQx fields in the _SB scope to reduce size of register references, define CRS and STA methods in _SB scope to reduce code duplication, simplify acpi code.

[PATCH 1/5] Reindent DSDT code.

by Kevin O'Connor

This patch is purely cosmetic - no code changes should be observed. Use a consistent indentation style with the ACPI DSDT code: 1 - Use spaces (no tabs) and 4 space indentation 2 - Place opening braces on same line as statement declaration 3 - Don't put a space between statement and opening parenthesis, except for control statements (If, Else, While, Return) where a space is always present Signed-off-by: Kevin O'Connor <kevin(a)koconnor.net> --- src/acpi-dsdt-cpu-hotplug.dsl | 131 ++++++------ src/acpi-dsdt-dbug.dsl | 42 ++-- src/acpi-dsdt-hpet.dsl | 54 +++-- src/acpi-dsdt-isa.dsl | 226 +++++++++----------- src/acpi-dsdt-pci-crs.dsl | 205 +++++++++--------- src/acpi-dsdt.dsl | 271 ++++++++++++------------ src/q35-acpi-dsdt.dsl | 480 ++++++++++++++++++++---------------------- src/ssdt-pcihp.dsl | 20 +- src/ssdt-proc.dsl | 14 +- src/ssdt-susp.dsl | 9 +- 10 files changed, 692 insertions(+), 760 deletions(-) diff --git a/src/acpi-dsdt-cpu-hotplug.dsl b/src/acpi-dsdt-cpu-hotplug.dsl index 7f3ad3b..0f3e83b 100644 --- a/src/acpi-dsdt-cpu-hotplug.dsl +++ b/src/acpi-dsdt-cpu-hotplug.dsl @@ -2,76 +2,77 @@ * CPU hotplug ****************************************************************/ -
