Hey,
I have a tablet that seems to be using Realtek chips to do wireless
communications (hopefully, this time I won't be wrong[1]).
The device, under the gpio class in /sys, shows with a modalias of
"acpi:OBDA8723:" (that's on "O", not "0"). This seems to correspond to a
Realtek chipset (Larry tells me it matches the PCI ID of 0bda:8723 for
the RTL8723AE chipset).
It shows up under:
/sys/devices/platform/80860F0A:00/subsystem/devices
Does anyone have details on how this chipset is actually hooked up? Can
a portion of the existing RTL8723AE driver code be reused?
Bastien,
From the previous response, it seems unlikely that GPIO is used to control the
device. That is what I expected. Working at that primitive level would be
extremely difficult timing.
I assume that you have checked both 'lspci' and 'lsusb' for any mention of the
wireless device. I am not aware of a similar utility to scan an SDIO bus, but
perhaps someone on this list will know. In addition, a full listing of 'lspci
-nnv' will give a clue regarding what adapters are on the device.
If the device were used with SDIO, then it would be known as the RTL8723AS. I
could not find that chip, but there is an RTL8723BS with a 32-bit driver for
Windows 8.1.
What specific Baytrail tablet do you have?
Larry
