Dear Chris and Reid:
Some other random ideas I've had as I've been sifting through the new
bytecode format. Please let me know what you think.
1) ANSI C allows for char to default to unsigned char. This is I guess not
how it normally is in GCC. If char defaulted to unsigned char several
things would be possible. Single char constants that are defined would be
almost always stored

[LLVMdev] Bytecode file bugs / doc bugs
Dear Reid and Chris,
I thought I should send this to the list in case anyone else is struggling
to interpret bytecode files with the new docs.
(1) First a bug I already mentioned to Reid. Unlike the other new
module headers module 0x01 still uses the old 32-bit and 32-bit format
instead of the new 5-bit and 27-bit format. Thus the first module in the
file will be 0x00000001 followed by

[LLVMdev] Bytecode Change: Compaction Tables gone.
All,
Last night I removed compaction tables from the bytecode format
(documentation change forthcoming). This was done for a few reasons.
First, its very expensive in CPU time to process compaction tables for
both reading and writing. Second, the maximum benefit we gained was
about 7% (600K a 9Mb bytecode). In most cases its in the 1% range or
actually makes the bytecode larger. Finally, as we

multiple devices in the same iommu group in L1 guest

I have a guest enabled vIOMMU, but on the guest there are several devices
in the same iommu group.
Could someone help to check if I missed something?

[LLVMdev] Re: Bytecodes & docs
Reid,
Thanks for the detailed feedback.
A value of zero now means zero literal for everything except labels,
right? There is kind of a vague reference to this in the 1.0 -> 1.1
section I believe. You might want to make this clearer when talking about
values in the body of the document.
--> A comment on this: if a value of zero were never used for labels, that
would make me happy,

Re: PCI Passthrough of 2 identical devices
hi laine,
thx for the fast answer.
i tried VFIO as it seems supported and got at least one step further.
starting the guest with one of the DVB cards is possible now, even when the other card is in the hosts pci config (not removed soft or hard).
adding the second card/device thru ...

[RFCv2 1/5] mm/compaction: enable driver page migration
Add framework to register callback functions and
check pages migratable.
There are some modes of page isolation so that isolate interface
has an arguments of page address and isolation mode.
