Severity: normal

Dear maintainer,

The bus of my laptop's Alcor Micro AU6625 is detected by the kernel
but there

isn't a driver for using it.

CONFIG_MISC_ALCOR_PCI is left unset in the kernel config used to build
this

package, although both source and header of the driver are present in
Debian's

kernel source tree and header tree.

The driver is just excluded from the compiled binary kernel.

$ uname -a

Linux portatilelorenzo 6.12.96+deb13-amd64 #1 SMP PREEMPT_DYNAMIC
Debian

6.12.96-1 (2026-07-20) x86_64 GNU/Linux

$ lspci -nn | grep -i alcor

04:00.0 Unassigned class [ff00]: Alcor Micro AU6625 PCI-E Flash card
reader

controller [1aea:6625]

$ cat /boot/config-$(uname -r) | grep -i alcor

# CONFIG_MISC_ALCOR_PCI is not set

$ find /usr/src/linux-headers-6.12.96+deb13-common -iname
"alcor_pci.h"

/usr/src/linux-headers-6.12.96+deb13-common/include/linux/alcor_pci.h

$ tar -tJf /usr/src/linux-source-6.12.tar.xz | grep -i alcor

linux-source-6.12/drivers/misc/cardreader/alcor_pci.c

linux-source-6.12/drivers/mmc/host/alcor.c

linux-source-6.12/include/linux/alcor_pci.h

Is this exclusion intentional? If it isn't, would it be possible in
future

builds to enable CONFIG_MISC_ALCOR_PCI and CONFIG_MMC_ALCOR needed for

supporting this adapter?

Thanks!
