Bernhard Kaindl enhanced firescope to support accessing 64-bit machines
from 32-bit firescope and vice versa:
- ftp://ftp.suse.de/private/bk/firewire/tools/firescope-0.2.2.tar.bz2
- http://halobates.de/firewire/firescope-0.2.2.tar.bz2
and he implemented fast system dump (alpha version - read README.txt):
- ftp://ftp.suse.de/private/bk/firewire/tools/firedump-0.1.tar.bz2
- http://halobates.de/firewire/firedump-0.1.tar.bz2
There is also a gdb proxy for firewire which allows to use gdb to access
data which can be referenced from symbols found by gdb in vmlinux:
- ftp://ftp.suse.de/private/bk/firewire/tools/fireproxy-0.33.tar.bz2
- http://halobates.de/firewire/fireproxy-0.33.tar.bz2
The latest version of this gdb proxy (fireproxy-0.34) can communicate (not
yet stable) with kgdb over an memory-based communication module (kgdbom).

@ -451,3 +451,33 @@ Why: OSS sound_core grabs all legacy minors (0-255) of SOUND_MAJOR
will also allow making ALSA OSS emulation independent of
sound_core. The dependency will be broken then too.
Who: Tejun Heo <tj@kernel.org>
----------------------------
What: Support for VMware's guest paravirtuliazation technique [VMI] will be
dropped.
When: 2.6.37 or earlier.
Why: With the recent innovations in CPU hardware acceleration technologies
from Intel and AMD, VMware ran a few experiments to compare these
techniques to guest paravirtualization technique on VMware's platform.
These hardware assisted virtualization techniques have outperformed the
performance benefits provided by VMI in most of the workloads. VMware
expects that these hardware features will be ubiquitous in a couple of
years, as a result, VMware has started a phased retirement of this
feature from the hypervisor. We will be removing this feature from the
Kernel too. Right now we are targeting 2.6.37 but can retire earlier if
technical reasons (read opportunity to remove major chunk of pvops)
arise.
Please note that VMI has always been an optimization and non-VMI kernels
still work fine on VMware's platform.
Latest versions of VMware's product which support VMI are,
Workstation 7.0 and VSphere 4.0 on ESX side, future maintainence
releases for these products will continue supporting VMI.
For more details about VMI retirement take a look at this,
