Adds for dynamic AML creation, which will be used
for piecing ASL/AML primitives together and hiding
from user/caller details about how nested context
should be closed/packed leaving less space for
mistakes and necessity to know how AML should be
encoded, allowing user to concentrate on ASL
representation instead.
For example it will allow to create AML like this:
AcpiAml scope = acpi_scope("PCI0")
AcpiAml dev = acpi_device("PM")
aml_append(&dev, acpi_name_decl("_ADR", acpi_int(addr)))
aml_append(&scope, dev);

From: Igor Mammedov @ 2014-12-19 2:02 UTC (permalink / raw)
To: qemu-devel; +Cc: pbonzini, drjones, claudio.fontana, mst
Replace AML template patching with direct composing
of PCI device entries in C. It allows to simplify
PCI tree generation further and saves us about 400LOC
scattered through different files, confining tree
generation to one C function which is much easier
to deal with.

QEMU doesn't implement/advertize PM1b_CNT_BLK
register block so do not set/patch its \_Sx
values to avoid confusion.

Replaces template patching with packages composed
using ASL API.
Note on behavior change:
If S3 or S4 is disabled, respective packages won't
be created and put into SSDT. Which saves us some
space in SSDT and doesn't confuse guest OS with
mangled package names as it was done originally.

Named/Reserved{Field} definition uses PkgLength [1] encoding to specify
field length, however it doesn't include size of PkgLength field itself,
while other block objects that have explicit length of its body account
for PkgLength size while encoding it [2].
This special casing isn't mentioned in ACPI spec, but that's what 'iasl'
compiles NamedField to so add extra argument to build_prepend_pkg_length()
to allow it handle the case.

Drops AML template patching and allows to
save some space in SSDT if pvpanic device doesn't
exist by not including disabled device description
into SSDT. It also makes device description
smaller by replacing _STA method with named value
and dropping _INI method.

it replaces a static complied in DSDT MMIO region
for CPU hotplug with one created at runtime
leaving only truly static CPU hotplug related ASL
bits in DSDT.
It also puts CPU_HOTPLUG_RESOURCE_DEVICE into
PCI0 scope and reserves resources from it,
preparing for dropping manual hole punching
in PCI0._CRS.
Later it also would make easier to reuse current
ACPI CPU hotplug on other targets.
Also later it would be possible to move remaining
CPU hotplug ASL methods into build_ssdt() and
add all CPU hotplug related AML into SSDT only
when CPU hotplug is enabled, further reducing
ACPI tables blob if CPU hotplug isn't used.
impl. detail:
Windows XP can't handle /BSODs/ OperationRegion
declaration in DSDT when variable from SSDT is used
for specifying its address/length and also when
Field declared in DSDT with OperationRegion from
SSDT if DSDT is being parsed before SSDT.
But it works just fine when referencing named
fields from another table. Hence OperationRegion
and Field declaration are moved to SSDT to make
XP based editions work.
PS:
Later Windows editions seem to be fine with above
conditions.

From: Igor Mammedov @ 2014-12-19 2:02 UTC (permalink / raw)
To: qemu-devel; +Cc: pbonzini, drjones, claudio.fontana, mst
it replaces a static complied in DSDT MMIO region
for memory hotplug with one created at runtime
leaving only truly static memory hotplug related
ASL bits in DSDT. And replaces template patching
of MEMORY_SLOTS_NUMBER value with ASL API created
named value.
Later it also would make easier to reuse current
ACPI memory hotplug on other targets.
Also later it would be possible to move remaining
memory hotplug ASL methods into build_ssdt() and
add all memory hotplug related AML into SSDT only
when memory hotplug is enabled, further reducing
ACPI tables blob if memory hotplug isn't used.

Replace template patching and runtime
calculation in _CRS() method with static _CRS
defined in SSDT.
It also drops manual hole patching for reserved
PCI/MEM/CPU hoptlug MMIO resources and utilizes
the fact that MMIO resources are reserved by
respective child /i.e. PHPR, MHPD, PRES/ containers.

This is a good idea. It's simpler to just do this in the SSDT than to
split it between DSDT and SSDT. The AML's purpose is just to build a
static value anyway.

I think Marcel has patches going in exactly the reverse

Actually I added the CRS for the extra root buses in SSDT.
The reason is that it depends on user input.
By the way, I have the code for creating the CRS in code rather that in
the file based on Igor's series.
Thanks,
Marcel

From my talk with him, he was doing/needs a similar thing.
So this was simplifying his job.

keeping bios-linker-loader.c i386 specific would break build
of mips target which is built with CONFIG_ACPI which would
dependend on it in following patch that adds acpi_def_block()
term. Also UEFI for ARM target is going to use linker as well
so it makes sense to move it into generic target independent
ACPI part.

it allows to hide linker and direct access to table's
storage from table building function if it would use
acpi_def_block() to declare table and ASL/AML API to
compose it. Which following patch will do for
build_ssdt() function.
Signed-off-by: Igor Mammedov <imammedo@redhat.com>

PS:
this series does it only for build_ssdt(), but it also
could be done for other tables later by using there
acpi_def_block() to describe table's header and
adding addtional API to compose table's entries.

It completes dynamic SSDT generation and makes it
independed of IASL binary blobs. It also hides
from user all pointer arithmetic when building
SSDT which makes resulting code a bit cleaner
and concentrating only on composing ASL construct
/i.e. a task build_ssdt() should be doing/.
Also it makes one binary blob less stored in QEMU
source tree by removing need to keep and update
hw/i386/ssdt-misc.hex.generated file here in total
saving us ~430LOC.
