Integrated memory card reader not recognized

[Giova84]

Haiku hrev51706 gcc2h - on Asus Z8100G.

This laptop is provided with a multi format card reader: on Linux Mint 12 this card reader is recognized and working; on Haiku, if I insert a memory card and I look to DriveSetup app, nothing is recognized (and so to the "Mount" menu on the Desktop).

I attach syslogs which I take 2 days ago and output of listdev (Haiku) and lspci (Linux) https://dev.haiku-os.org/attachment/ticket/13904/syslog https://dev.haiku-os.org/attachment/ticket/13904/previous_syslog

Just curiosity: in ticket:13907 the WLAN adapter is not recognized because is listed as USB (on this laptop is internal); why this card reader (still internal), instead, is not recognized? I have a more modern Desktop PC where the integrated card reader is recognized. This laptop is also provided with a PCMCIA card slot; maybe could I have more luck by inserting a PCMCIA card reader? Is supported by Haiku?

Looks like there is a pcmcia bus manager ​http://cgit.haiku-os.org/haiku/log/src/add-ons/kernel/drivers/bus/pcmcia, however I don't think it works yet? Probably a dupe of #3702.

[Giova84]

To be clear: this integrated card reader is not installed in the PCMCIA slot: is present on the motherboard itself, and by listdevice is recognized:

device Mass storage controller (IDE interface) [1|1|80]
  vendor 1039: Silicon Integrated Systems [SiS]
  device 5513: 5513 IDE Controller

Replying to diver:

Looks like there is a pcmcia bus manager ​http://cgit.haiku-os.org/haiku/log/src/add-ons/kernel/drivers/bus/pcmcia

However: by doing a query for pcmcia on Haiku, I see that there are only headers files (no driver in binary format), presents in /boot/system/develop/headers/os/drivers/pcmcia folder, so I assume that not everything is integrated on Haiku. But, I repeat (I fear that I hasn't been good to expres myself :-) this card reader is not installed in the pcmcia slot.

Giova84: lets play with the words: It is actually recognized as listdevice lists it. It just have no driver to exploit the hardware capability.

Yep, it isn't PCMCIA attched, but directly to the PCI bus. Some of them works with Haiku (AFAIK) But the problem is: there is no generic PCI attached card reader, all the manufacturer implements an own home-made standard (AFAIK), so it isn't easy to provide a working driver for all of them.

I think one get better chanches with USB attached card reader (internal or external). They are at least standardized (AFAIK).

Hi,

What you list is an IDE controller (for hard disks), not a card reader. It does not seem to be on the USB bus either, or at least our USB driver does not see it there.

What is the device name on Linux? /dev/sdx or /dev/mmcblkx ?

Hi Giova84,

You actually have this as your MMC/SD reader:

Ricoh Co Ltd RL5c476 II (rev ac):
	device Bridge (CardBus bridge) [6|7|0]
	  vendor 1180: Ricoh Co Ltd
	  device 0476: RL5c476 II

Indeed, it seems this device is a multifunction device handling PCMCIA ports, SD card reader and smartcard reader. I don't know if we can get the SDHCI driver to work with it, as maybe they have shifted registers around to make it work. And, I can't find a spec for it explaining how they have separated the various functions.

Ricoh SDHCI controllers should now work after hrev54840.

As I mentionned in my previous comment, this specific device isn't handled by the driver yet.

There is a driver in Linux: ​https://elixir.bootlin.com/linux/v5.11-rc2/source/drivers/mmc/host/sdricoh_cs.c

It is in fact an internal PCMCIA device. The driver itself is not very complicated, but we don't have a PCMCIA stack at the moment.
