Palacios Public Git Repository
To checkout Palacios execute
git clone http://v3vee.org/palacios/palacios.web/palacios.git
This will give you the master branch. You probably want the
devel branch or one of the release branches. To switch to the devel
branch, simply execute
cd palacios
git checkout --track -b devel origin/devel
The other branches are similar.

expose RTM cap in CPUID
Maciek Swiech [Tue, 25 Mar 2014 15:44:31 +0000]
addition of print macros for RTM code
Kyle Hale [Tue, 25 Mar 2014 00:09:37 +0000]
significant refactoring of RTM emulation code
This is the first cut at a refactor of the transactional memory
extension. Most changes have been to reduce large function sizes, and
to reduce footprint in changes to Palacios core files. There are
several bug fixes as well, and this gets us to the point where we
can run thousand-transaction benchmarks on single-core.
At this point our main limitations are yet-to-be implemented
architectural features (coming soon) and limitations in the
quix86 decoder.

HPET does not abort load/save

Minor bug fix
Kyle Hale [Thu, 6 Mar 2014 19:19:28 +0000]
Added HPET (High Precision Event Timer) device
This is an initial implementation of a virtual HPET. Does not support
checkpoint save/restore yet. The HPET is currently defined to run at
1/16th of guest time
Note that a typical guest will check for the existence of the HPET
via an ACPI table. To force the current SeaBios to build this table
apply the following patch to it. This will eventually be automatic.

Bugfix to base memory region lookup
Peter Dinda [Tue, 26 Nov 2013 01:37:40 +0000]
Minor tweaks
- vmxassist doesn't print errors for information output
- guest config script cleanup
Peter Dinda [Tue, 26 Nov 2013 01:35:07 +0000]
Allow strict MSR semantics
When enabled, reads/writes to MSRs we do not handle cause GPF to be injected.
This is the architecturally specified reaction.
When disabled, our more lenient behavior is used (read=0, write=ignored)
Peter Dinda [Tue, 26 Nov 2013 01:32:00 +0000]
Allow custom CPUID
- when enabled, guest sees a strictly controlled cpuid result
with a "V3VEE" cpu vendor, etc. This is intended to help with
cross-architecture migrations where we want to prevent the
the guest from doing anything specific to the eratta of the
startup CPU.
- when disabled, guest sees former behavior (cpuid of host
masked for functionality we cannot support)

Floating point context-switching and checkpoint/load
This integrates:
- the option to do floating point context-switching
- conservative code to do context-switching in Palacios
- a lazy floating point save/restore host interface
- an implementation of this interface in the linux module
- liberal code to use this interface in Palacios
- floating point checkpointing
This also includes a performance tuning element that
is hard to separate

Dynamic migration of memory from node to node
This adds the ability to move memory regions of a VM from user space:
v3_mem_move /dev/v3-vmX guest_paddr host_cpuid
This will move the memory region in which guest_paddr is contained
from its current numa node to the one affiliated with host_cpuid
Combined with v3_core_move, this should provide the ability to
dynamically manipulate NUMA mappings at runtime, to the granularity
of the v3_mem_block_size (which is selected at insmod time)

more paranoid error checking
These changes handle the case in which v3_free_vm is called

prone are the non-pointers in the v3_vm_info struct that have list_head elements.

Constraints in page allocation, and code changes to use them; shadow paging allocations below 4 GB
This updates the page allocation os hook to take a "constraints" parameter. Currently,
there only one constraint, allocation below 4 GB. The buddy allocator and other elements
of the support code now obey this constraint. I have vetted page allocations in Palacios
so that with a guest using shadow paging, any allocation that could become part of the
guest memory map, and any allocation done in 32 bit shadow paging (page tables) is done
with this constraint. THis includes direct paging. Nested paging should be unaffected.
