[PATCH 00/20] q35 support patch series

[Gerd Hoffmann]

        Hi,

Next round of the q35 patch series, rebased to master. 

Patches 1-6 carry the C code bits.  They have been adapted to the recent
changes in master.  mcfg acpi table generator simply uses the q35
constants as suggested by Kevin.  Otherwise unmodified.

Patches 7+ carry the ACPI bits.  First the original unmodified dsdt
patches, then a bunch of cleanup patches on top of that which for the
most part split sharable AML code into separate files.

cheers,
  Gerd

PS: Anthony just pulled the q35 patches into qemu/master.

[PATCH 01/20] seabios: make mttr UC area setup dynamic

[Gerd Hoffmann]

      From: Jason Baron <jbaron(a)redhat.com&gt;

Set up the UC area of mtrr dynamically based on mtrr_base. This allows
the bios to work for other chipsets that might want to set the mtrr.
Since BUILD_MAX_HIGHMEM is no longer used we can remove the config parameter.

This change reverses the order of pci_setup() and smm_init() with
mtrr_setup().

I think this needs to be re-worked given Keven's commit:

commit b1c35f2b28cc0c94ebed8176ff61ac0e0b377798
Author: Kevin O'Connor <kevin(a)koconnor.net&gt;
Date:   Mon Nov 26 11:05:32 2012 -0500

    pciinit: Align start of PCI memory on i440 chipset.

We can use 'pcimem_start' instead of introducing 'mtrr_base'. Perhaps, we
should also add a check that the value of 'pcimem_start' is one of:

0x80000000
0xc0000000
0xe0000000

Although I think we just need a warning for that case, not a hard error.

Thanks,

        Hi,

  We can use 'pcimem_start' instead of
introducing 'mtrr_base'. Perhaps, we
 should also add a check that the value of 'pcimem_start' is one of:
Oops, the mtrr_base assignment got lost in the whole rebasing process.
That wasn't intentional.

Given that pcimem_start and mtrr_base have the same value for both piix4
and q35 we could drop one indeed.

cheers,

[PATCH 05/20] simplify chipset detection

[Gerd Hoffmann]

      Just set a global variable in the first chipset detection
function (pci_bios_init_platform) and use them later on.

I liked the original way better.  The pci_init_device() function is
pretty cheap (it just walks a linked list).  The code is slightly more
verbose, but I think it's more clear what's occurring.


Besides the few minor comments, I'm okay with this patch series.

 verbose, but I think it's more clear what's occurring.
On its own the patch doesn't make that much sense indeed, but see also
patch #6 (add mcfg table, for q35 only) which will become a bit more
complicated without the global variable.

cheers,

[PATCH 07/20] seabios: q35: add dsdt

[Gerd Hoffmann]

      From: Isaku Yamahata <yamahata(a)valinux.co.jp&gt;

add dsdt for q35 chipset of qemu.

[jbaron: remove suspd bits since they are now auto-generated, move pci window to
0xb0000000,
    add framework for auto generated pci windows]

I think we should drop this entire pcie root port/bridge sections, at
least for now. These were here from when qemu was creating a default set
of bridges and pcie root ports. Now that we've gone to a model where we
have a minimal set of default devices, this doesn't match what qemu is
doing. We might need to re-visit this at a later point, but I think we
should drop it for now.

Thanks,

[PATCH 07/20] seabios: q35: add dsdt

[Gerd Hoffmann]

        Hi,

  I think we should drop this entire pcie root
port/bridge sections, at
 least for now. These were here from when qemu was creating a default set
 of bridges and pcie root ports. Now that we've gone to a model where we
 have a minimal set of default devices,
Not that I'm a big fan of that ...

  this doesn't match what qemu is
 doing. We might need to re-visit this at a later point, but I think we
 should drop it for now.
Makes sense.  Especially as there seem to be leftovers for non-ich9 test
devices.

cheers,
  Gerd

I think this makes sense.  However, I think it would be nicer to put
an explicit scope at the beginning of the file (ie, Scope (\SB.PCI0) )
instead of nesting the include.

I'll try.  IIRC I've had problems with iasl complaining about duplicate
devices in a simliar case, so I'm not sure this works out.

These methods really shouldn't return anything - it was an error in
the previous DSDT versions which newer iasl compilers warn about.
Instead of introducing the Return, the q35 dsdt should be updated to
not return a value.

[PATCH 17/20] acpi: rework enable bits

[Gerd Hoffmann]

      Model the device enable bits as fields so they can be accessed
directly by name.

[PATCH 18/20] acpi: move isa devices to separate file

[Gerd Hoffmann]

      Stuff them parameterized into #defines, so we can (a) reuse them for
q35 and (b) don't duplicate the serial line.

 Shouldn't that be
 Device (_name) ?
 Yes, it should.
 So make it so :-)
Sure.  Will wait a day for more review comments before re-spinning
though.  I've spammed the list enougth for today by sending the series
twice by mistake.

I'm not a big fan of complex macros in the iasl code.

The only difference I see between the above and the q35 code is
\_SB.PCI0.PX13 vs \_SB.PCI0.LPC.  However, as I understand it, the
choice of PX13 or LPC is arbitrary - so I think we should just be able
to choose a consistent name between the two dsdt codes.  That way we
shouldn't need the macros.

On second thought - maybe a better solution is to just inject the
field definitons into \_SB.PCI0.ISA and \_SB.PCI0.LPC.

The OperationRegion has to be in the proper device (eg, PX13), but the
Field() can go anywhere.  So, if the PIIX dsdt code had something
like:

       Scope (\_SB.PCI0.ISA) {
           Field (\_SB.PCI0.PX13.P13C, AnyAcc, NoLock, Preserve)
           {
                Offset(0x5f),
               , 7,
               LPEN, 1,         // LPT
                Offset(0x67),
               , 3,
               CAEN, 1,         // COM1
               , 3,
               CBEN, 1,         // COM2
           }
       }

then the isa devices could just access LPEN/CAEN/etc without requiring
an explicit path.

 an explicit path.
Nice, thanks for the idea.

/me tried to find something like this without success before going the
macro route.

cheers,
