Now _REG, _STA, _INI are called in the order my laptop expects them to
be called. This was kinda weird because what uACPI was doing did not
work.
\_SB_.PCI0.LPC0.EC0_.BAT0._STA required \_SB_.PCI0.LPC0.EC0_._REG to be
called
\_SB_.PCI0.LPC0.EC0_._REG required \_SB_.PCI0._STA to be called
Now I call all the _REG methods of a device after calling _STA/_INI and
after performing the whole _STA/_INI sequence i call rest of missing
_REG functions
The old AML interpreter was trash and did not follow value/reference
semantics at all. It was also super slow, one of my machines taking over
7 seconds to parse ACPI namespace and call _INI and _STA.
Node now have APIs to convert them to buffer, integer and string. This
allows possibility to handle methods that need explicitly use one of the
overloads instead of integer.
This patch also adds handling of DebugOp. This is used quite heavily in
uACPIs test suite.
Remove tree-like structure from AML. This allows more spec compliant
parsing of named objects inside not yet declared devices.
This also allows AML to be run thread safely. All object adds/removes
are now guarded by a mutex.
Now global lock uses the actual global lock. Currenly if no lock
can be acquired, we just panic the kernel so that I remember to
implement it properly once AML is running concurrently.
Method invocation is starting to come together. This implemenetation
can interpret some of the qemu's functions to enter ACPI mode.
PCI config space access is currently the one thing is between
entering ACPI mode.
Now AML parsing is actually done while respecting namespaces and
scopes. I implemented the minimal functionality to parse qemu's AML.
Next step is to implement AML interpreting and then we can drop lai
as a dependency.
