PCI passthrough of a SATA/PATA controller, "FLR functionality not supported"
Hi there,
I have a question regarding PCI passthrough on the Citrix XenServer 5.6
(Xen 3.4.2).
I already managed to get some soundcard passed through to a Windows
guest. So I think my knowledge about that topic isn''t _that_ low. But I
cannot seem to pass through a SATA/PATA controller to a Linux guest.
I have some additional CD/DVD burner (PATA) attached to a SATA/PATA
controller

[PATCH] Improve the current FLR logic
Hi, all,
The attached patches try to improve the current FLR logic.
The idea is: removing the FLR logic from hypervisor and adding the
improved logic in Control Panel.
The current FLR logic in hypervisor has some issues: 1) Dstate
transition is not guaranteed to properly clear the device state; 2) the
current code for PCIe FLR is actually buggy: PCI_EXP_DEVSTA_TRPND
doesn''t mean the

VGA Passthru - FLR?
Hi, everyone. I''m Guilherme Suzuki (brazillian, by the way) and really
interested in xen-vga-passthru.
Lately, I bought a brand new Saphire HD 7950 (OC Boost) because I saw in a
wiki somewhere that users have been able to passthru these VGA devices to
domU (win7, win-xp and so on).
But, after I installed it, I executed *lspci -vv* to check if FLR in DevCap
was present (which

How vital is having "FLReset+" for VGA Passthru in DomU?
I was reading the Wiki page here: http://wiki.xen.org/wiki/VTd_HowTo

Status of FLR in Xen 4.4
Hi everyone,
I would like to ask what the current status of FLR, or better of FLR
emulation is in latest Xen and if we can expect better support in the
future.
I''m asking because with xl (latest build and traditional qemu, not
upstream), I always had problems with rebooting domUs which have vga cards
passed through to them, because appearently they don''t get reinitialized

AW: Workaround for pcifront issues
Thanks Anna, this was also quite interesting for me.
Did you mean that I just have to eliminate the else branch or raise arround "All devices
behind the uppermost PCI/PCI-X bridge must be co-assigned to the same guest." or do I have
to eliminate more in order to prevent an FLR (whatever that is).
For my board it''s definitely necessary to move PCI devices in different guests,

Now it comes downgrade or install two R versions under Linux
R-sig-Debian help,
Yesterday I sought help regarding R upgrading from R-2.8.1 to R-2.9.1.
I must thank specially Dirk for his helpful advice.
But now I am facing a dilemma. I want to install a package called FLR which
works under R-2.8.1. So my question is whether I can keep the latest release (R-2.9.1)
and also install R-2.8.1 (and if feasible how.)
Alternatively I could uninstall R-2.9.1 and

Different floor, quality improvement
Hello all,
Please try this "patch". It changes the way the noise floor is used
for quantization in a not-so-subtle way.
At the very end of _vp_compute_mask, add the lines:
for(i=0;i<n;i++)
flr[i]=.01f*sqrt(flr[i]);
The .01 is there to ensure the current codebooks will work. We will
really need different, newly-trained codebooks with this change; then

histogram method for S4 class.
Hi,
I'm trying to develop an histogram method for a class called "FLQuant"
which is used by the package FLCore (http://flr-project.org). FLQuant is

[PATCH] Support Function Level Reset (FLR) in the xen-pciback module (v1) and some fixes.
The attached patches allow the pciback module to perform a reset whenever
a PCI device is:
- attached to the pciback module, as so:

- detached from the pciback module, as so:

extending lattice to S4 classes
Hi,
I'm writing methods for a package called FLCore (see
http://flr-project.org/) in particular for a class called "FLQuant"
which extends array.
Previously I was able to write methods based on the class of "data" but
now I can not do it due to the single parameter "x". Is there a way to
do this ?

Strange PCI Passthrough problem
