sd card reader is Not found

Hey,

I know this topic was discussed many times before but I can't find a solution for me.
I updated fro kernel 3.6.11 to 4.1.12. Now pretty much everything works fine, but my integrated SD/MMC card reader.

lspci:

04:00.0 Unassigned class [ff00]: Realtek Semiconductor Co., Ltd. RTS5209 PCI Express Card Reader (rev 01)
Subsystem: Acer Incorporated [ALI] RTS5209 PCI Express Card Reader
Flags: bus master, fast devsel, latency 0, IRQ 7
Memory at b0501000 (32-bit, non-prefetchable) [size=4K]
Capabilities: [40] Power Management version 3
Capabilities: [50] MSI: Enable- Count=1/1 Maskable- 64bit+
Capabilities: [70] Express Endpoint, MSI 00

04:00.1 SD Host controller: Realtek Semiconductor Co., Ltd. RTS5209 PCI Express Card Reader (rev 01)
Subsystem: Realtek Semiconductor Co., Ltd. RTS5209 PCI Express Card Reader
Flags: bus master, fast devsel, latency 0, IRQ 19

Capabilities: [90] MSI: Enable- Count=1/1 Maskable- 64bit+
Capabilities: [b0] Express Endpoint, MSI 01
Kernel driver in use: sdhci-pci
Kernel modules: sdhci_pci

So it seems my SD card reader will work. But when I insert a SD card, which I was able to read/write on my old kernel, I didn't get a new device in /dev and dmesg didn't output anything.

I tick on every single entry in my kernel config.

│ │ <M> USB SD Host Controller (USHC) support │ │
│ │ <M> Renesas USDHI6ROL0 SD/SDIO Host Controller support │ │
│ │ <M> Toshiba Type A SD/MMC Card Interface Driver │ │

But this was not successful. select everything as built in end up the same

I found something like: CONFIG_SCSI_MULTI_LUN=y in prior post but can't find a similar menu entry in my 4.1.12 kernel.
Thanks 4 your effort

I don't have a clue, but perhaps something about the following might lead to one...

My main laptop also has a Realtek controller for the memory card slot, albeit not a 5209. I had to make some changes in order to get it working. I'm not using a 4.* kernel yet, but perhaps the following description of what I did might be of some help to you:

I think what you need to enable for this card reader is CONFIG_MFD_RTSX_PCI.

CONFIG_SCSI_MULTI_LUN was necessary on older kernels for USB card readers.

hey guys!

I added some Hotplug modules like described here: https://fitzcarraldoblog.wordpress.com/ ... rd-reader/

ronny-reiner-rambo linux # cat .config | grep -i hotplug
CONFIG_MEMORY_HOTPLUG=y
CONFIG_MEMORY_HOTPLUG_SPARSE=y
CONFIG_HOTPLUG_CPU=y
# CONFIG_BOOTPARAM_HOTPLUG_CPU0 is not set
# CONFIG_DEBUG_HOTPLUG_CPU0 is not set
CONFIG_ARCH_ENABLE_MEMORY_HOTPLUG=y
CONFIG_ACPI_HOTPLUG_CPU=y
CONFIG_ACPI_HOTPLUG_MEMORY=y
CONFIG_ACPI_HOTPLUG_IOAPIC=y
# CONFIG_HOTPLUG_PCI_PCIE is not set
CONFIG_HOTPLUG_PCI=y
CONFIG_HOTPLUG_PCI_ACPI=y
# CONFIG_HOTPLUG_PCI_ACPI_IBM is not set
CONFIG_HOTPLUG_PCI_CPCI=y
# CONFIG_HOTPLUG_PCI_CPCI_ZT5550 is not set
# CONFIG_HOTPLUG_PCI_CPCI_GENERIC is not set
CONFIG_HOTPLUG_PCI_SHPC=y

and built

CONFIG_MFD_RTSX_PCI=m

as a module. lspci now looks like that:

04:00.0 Unassigned class [ff00]: Realtek Semiconductor Co., Ltd. RTS5209 PCI Express Card Reader (rev 01)

Capabilities: [70] Express Endpoint, MSI 00
Kernel driver in use: rtsx_pci

04:00.1 SD Host controller: Realtek Semiconductor Co., Ltd. RTS5209 PCI Express Card Reader (rev 01)

Capabilities: [b0] Express Endpoint, MSI 01
Kernel driver in use: sdhci-pci
Kernel modules: sdhci_pci

But it's still shown as: "Unassigned class [ff00]" and I got no device-folder in /dev. Thunar didn't recognize the reader either and dmesg did not throw any event.

royalts · Post by **royalts** » Sun Jan 10, 2016 8:10 pm

I'm not sure but do I need ACPI software to get it working?

chithanh · Post by **chithanh** » Sun Jan 10, 2016 10:16 pm

The "unassigned class" is not a problem of the kernel or driver, it is just that lspci has no database entry for it.

Do you get anything new in dmesg when you plug in a card?
If nothing happens: I am not sure whether the rtsx_pci driver should drive both devices, can you ensure that the rtsx_pci driver loads before the sdhci one at boot?

Fitzcarraldo · Post by **Fitzcarraldo** » Mon Jan 11, 2016 4:45 am

You have CONFIG_HOTPLUG_PCI_PCIE=n:

Code: Select all

# CONFIG_HOTPLUG_PCI_PCIE is not set

I have set it in my configuration:

Code: Select all

clevow230ss fitzcarraldo # grep -i hotplug /usr/src/linux/.config
# CONFIG_MEMORY_HOTPLUG is not set
CONFIG_HOTPLUG_CPU=y
# CONFIG_BOOTPARAM_HOTPLUG_CPU0 is not set
# CONFIG_DEBUG_HOTPLUG_CPU0 is not set
CONFIG_ARCH_ENABLE_MEMORY_HOTPLUG=y
CONFIG_ACPI_HOTPLUG_CPU=y
CONFIG_HOTPLUG_PCI_PCIE=y
CONFIG_HOTPLUG_PCI=y
CONFIG_HOTPLUG_PCI_ACPI=y
# CONFIG_HOTPLUG_PCI_ACPI_IBM is not set
# CONFIG_HOTPLUG_PCI_CPCI is not set
# CONFIG_HOTPLUG_PCI_SHPC is not set
CONFIG_UEVENT_HELPER_PATH="/sbin/hotplug"

Is the Realtek memory card controller a PCIE card in your machine? I believe my laptop has a PCIE card:

Code: Select all

clevow230ss fitzcarraldo # lspci | grep -i realtek
04:00.0 Unassigned class [ff00]: Realtek Semiconductor Co., Ltd. Device 5287 (rev 01)
04:00.1 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL8111/8168/8411 PCI Express Gigabit Ethernet Controller (rev 12)

royalts · Post by **royalts** » Mon Jan 11, 2016 1:14 pm

@chithanh: dmesg and udevadm monitor did't output anything. So how could I ensure rtsx_pci loads before sdhci?

@Fitzcarraldo: I added

cat /usr/src/linux/.config | grep 'CONFIG_HOTPLUG_PCI_PCIE'
CONFIG_HOTPLUG_PCI_PCIE=y

but the problem still remains.

Fitzcarraldo · Post by **Fitzcarraldo** » Mon Jan 11, 2016 3:15 pm

I have 'sdhci-pci' listed before 'rtsx_pci' in /etc/conf.d/modules:

Code: Select all

clevow230ss fitzcarraldo # cat /etc/conf.d/modules 
modules="r8169 nvidia agpgart fuse bnep rfcomm hidp uvcvideo cifs mmc_block sdhci-pci rtsx_pci snd-seq-midi vboxdrv vboxnetadp vboxnetflt"

but it appears that rtsx_pci loads earlier than sdhci:

Code: Select all

clevow230ss fitzcarraldo # dmesg | grep rtsx

ich put my PCI ID in here: http://kmuto.jp/debian/hcl/index.rhtmlx and i got as a result: Driver: rts_pstor.
This is in the package: sys-block/rts_pstor, but not available in the kernel config (which I don't understand :/ )
After install lspci -v lokks like that:

By the way: I found this in dmesg, too (appears very often)

What happens if you merge sys-block/rts_pstor and then rmmod rts_pstor && modprobe rts_pstor?

royalts · Post by **royalts** » Mon Jan 11, 2016 4:21 pm

That's It! rmmod rts_pstor && modprobe rts_pstor did it

So could I remove sdhci_pci,... or is this still needed and why are bot listed in my lspci -v (see post above)? Could a deive load/need two kernel modules?

Fitzcarraldo · Post by **Fitzcarraldo** » Mon Jan 11, 2016 4:50 pm

Try rmmod sdhci_pci and, if your card reader continues working, you'll know you don't need it as well.

EDIT: BTW, it looks like the rts_pstor driver was removed from 4.* kernels and presumably the rtsx_pci is intended to take its place:

CONFIG_RTS_PSTOR "found in Linux kernels: 2.6.39, 3.0–3.7"

CONFIG_MFD_RTSX_PCI "found in Linux kernels: 3.10–3.19, 4.0–4.2, 4.4"

CONFIG_MMC_SDHCI_PCI "found in Linux kernels: 2.6.27–2.6.39, 3.0–3.19, 4.0–4.2, 4.4"
