Right now, the SSDT/DSDT is split in three parts:
- code that doesn't need patching goes in the DSDT. Furthermore,
code in this category that is shared between PIIX4 and Q35 is
handled via #include. There was one exception, the SMC._STA
method is patched and is in the DSDT.
- shared code that needs patching goes in the SSDT
- template-based code that comes from command line arguments
goes in the SSDT as well
This series changes things to:
- code that is chipset-specific goes in the DSDT first.
Right now none of this needs patching
- code that is not chipset-specific, some of which needs
patching, goes in the DSDT second
- template-based code that comes from command line arguments
goes in the SSDT
Patch 1 moves ssdt-misc ("common code that needs patching")
to the DSDT. Patches 2-4 stop using the C preprocessor
in the DSDTs, except for parameterized code (CPU hotplug,
PCI CRS).
Patches 5-7 show why this could be useful. They add padding
in fw_cfg after the DSDT, and in exchange stop padding the ACPI
tables to 128K. This fixes migration problems (ROM sizes, RSDP)
because the ACPI tables are split in two:
1) fixed tables and the DSDT can be changed freely;
2) tables that vary depending on the command-line arguments (SSDT,
MADT, ...) are versioned and, given a machine type, they have to be
byte-equivalent across QEMU versions >= 2.3.
Patches 5 and 6 introduce a new sizing algorithm. Patch 7 use it
to fix the migration problems.
Only the first 4 or 6 patches are meant for inclusion. Patch 7 should
only be committed after Igor's series that rewrites the templating
mechanism in C. That makes it much simpler to track changes to the ACPI
tables, and removes dependencies on the IASL version that could cause
some head-scratching.
The conflicts with Igor's series are nontrivial but overall
not complicated to solve. Igor rewrote ssdt-misc in C, but those
parts can be easily removed from his series. He has plans to
build the DSDT from C, and if that materializes it can apply to
acpi-dsdt-common.dsl too.
v1->v2 fixes problems due to GArray resizing and updates test data.
Now passes make check.

Paolo Bonzini (7):
pc: append ssdt-misc.dsl to the DSDT
pc: rename ssdt-misc to dsdt-common
pc: move common parts of the DSDT to dsdt-common
pc: merge DSDT common parts into acpi-dsdt-common.dsl
pc: introduce new ACPI table sizing algorithm
pc: clean up pre-2.1 compatibility code
pc: go back to smaller ACPI tables

The DSDT is being patched anyway for the SMC. So "the DSDT is dynamic, the SSDT is static" is not something that happens anyway. The truth is "the SSDT (apart from ssdt-misc) defines Devices each of which comes from a template".

The complication arises if we want to make the SSDT exactly the same for all QEMU versions, given a (machine type, command line) pair.

I'm fine with moving "SMC out of the per-machine-type AML", should be a separate patch anyway. But patch-able SMC being in DSDT is our mistake that we allowed it to slip there and should be better moved to SSDT rather than staying in DSDT and making thing more complex. It's also candidate for trimming, i.e. dropping it from tables altogether if device is not present in QEMU, same applies to _S[34] Packages when respective features are disabled and to PEVT device template. > > >> simpler.

With resizable ROM blobs in master, there shouldn't be an issue with migration in new QEMU versions if size of SSDT changes. So question is if we still need SSDT version-ing and per machine type SSDT compatibility? /it's better not to do version-ing at all if it could be avoided, due to maintenance headache it brings along/ PS: could you split binary/hex blobs update in separate patch(s), to simplify review/testing of series. > > Paolo ^ permalink raw reply [flat|nested] 27+ messages in thread

There is only a very small issue that remains (the RSDP pointer is wrong if the size changes), so we probably should apply anyway the patch of mine that allows the DSDT size to change; and we probably should pay attention to SSDT, and version it. ("Let's just ignore the SSDT" was exactly what I feared when I disagreed with putting in resizable ROM blobs first. But now that it's in, I cannot really argue otherwise). > So question is if we still need SSDT version-ing and per machine type > SSDT compatibility? /it's better not to do version-ing at all if it could > be avoided, due to maintenance headache it brings along/ I'm okay with re-evaluating that after your patches go in.

There were my patches on list that move RSDT at the start of blob, which fixes issue for new machine types. That patches however weren't doing good job for old machine types.

A harder way would be to allow rom files to share an MR. We could then stick RSDP at the tail of the MR, and look for it on incoming migration: if there, fix it up.

Also, with the new rule that SSDT cannot change except with machine-type compat code, the magic 97 constant for a CPU's AML size is not anymore "legacy", so rename it.
