Rajesh Hi Rajesh, While waiting for a p2p bridge hotplug support, I give a try to linux-2.6.12rc2-mm3 which include your patch for powering on and off an ACPIPHP controlled PCI slot without actually remove the pci card. I gave it a try on my IBM thinkpad booted in docking station which has an ACPIPHP slot. An echo 0 /sys/bus/pci/slots/SOME_NUMBER/power is removing some devices ( verified with cat /proc/pci ), but gives some kernel errors on console. An echo 1 /sys/bus/pci/slots/SOME_NUMBER/power is not activating the devices again ( again tested with cat /proc/pci) but gives some kernel errors on console + some cpu registers and a segfault. In my dock I have a ide controller, 2 yenta pcmcia slots, and a PCI slot where I have a bttv supported tv card. All drivers needed were compiled in kernel, no modules needed. Was this setup supposed to work ? I can provide more info if needed. Thanks, Paul __ Do You Yahoo!? Tired of spam? Yahoo!

The added hierarchy may contain other p2p bridges and end/leaf I/O devices too. The root bridge itself is assumed to have been assigned resource ranges, but the p2p bridges and end devices are not required to be initialized by firmware. Most of the code changes are to make the existing code flows suitable for such a hierarchy of bridges devices. This code supports hot-add on ia64 only for now.It does not yet support I/O APIC hot-add, which is needed to make this fully functional. The patches are against 2.6.11-mm4 (plus the patch needed for ia64 to boot). I've tested to make sure this does not break end/leaf device hotplug on the hotplug capable ia64 box I have. Thanks, Rajesh Does this mean that when it will be ported for i386, I will be able to really use my Docking Station ? Does it rescan the DSDT to find new additions to ACPI devices ? I have an IBM docking station with a PCI bus inside and some other devices, and when I hot plug my IBM ThinkPad T41 in it, it does not recognize those devices. Only if I boot in dock they are usable. And the DSDT is different if I boot in dock or not. So I wander if this patch would help me to hot plug my T41 in the dock and all devices will be recognized. (when the patch will be for i386 too) Thx, Paul - To unsubscribe from this list: send the line unsubscribe linux-kernel in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/

No. The current patches only trigger when a _root_ bridge is hot-added, not a PCI to PCI bridge (which is what the docking station is). The code to support p2p bridge hotplug will benefit from these patches but more code is needed to support that. Thanks for the info. Is p2p hotplug in your roadmap (for i386) ? Can you please give me an example of a root bridge ? Thanks, Paul __ Do you Yahoo!? Yahoo!

Re: intel8x0 and 2.6.11-rc1
Hi Takashi, The same applies for IBM T40/T41/R50p I have tested so far. I had to disable Headphone Jack Sense and Line Jack Sense too. So, what's the deal with these ? What are they supposed to do ? Should we report this as bug on alsa lists ? Thanks, Paul On Thu, 20 Jan 2005 16:55:55 +0100, Takashi Iwai wrote: If you have Headphone Jack Sense mixer control, try to turn it off.
