PCI Rescan Problems with Fakephp

PCI Rescan Problems with Fakephp

[Daniel Qarras]

Hi,

Summary: a patch seems to be needed for fakephp to get proper hotplug
events but the reason why the patch is needed is unclear.

Longer version: I have an Acer Aspire 1692 WLMi laptop (1) with a Texas
Instruments FlashMedia xx12/xx21 memory card controller (MMC) that has
two modes of operation: TI's own proprietary FlashMedia and the
standard SDHCI interface. By default, the proprietary mode is in use
and to use the SDHCI mode one needs to disable the FlashMedia part and
enable the SDHCI part. It seems that the best way to achieve this is by
using PCI hotplug events (2). However, as mentioned in (2) a patch is
needed for the fakephp module and this of course makes life hard for an
ordinary user. I would like to know is there any other way to enable
the SDHCI part on my TI chip other than using the patched fakephp or
would it be possible to apply the patch to the fakephp driver? I'll
provide any additional information that you might need. Thanks.

Try the pci hotplug mailing list instead, this list is for the linux
hotplug scripts and udev stuff :)

thanks,
