Hi

I am making a new topic for rts_bpp & Gentoo kernel 3.6.0, 3.6.1

Previous one, RTL8411 - rts_bpp is here:
http://forums.gentoo.org/viewtopic-t-922794.html

For the last months the solution from topic above was fine for every new kernel: make, make install, depmod, reboot and card reader did work.

Unfortunately it doesn't work with new Gentoo-kernel 3.6.0 & 3.6.1. I tough maybe there is a problem with a new kernel, but developer who did make this driver (rts_bpp) said it works for him for a new kernels. So I've made some research for Gentoo.

Code:
*  sys-kernel/gentoo-sources
      Latest version available: 3.6.1
      Latest version installed: 3.6.1
      Size of files: 80,408 kB


[1] Looks like here everything is OK like for previous kernels:

Code:
# make
cp -f ./define.release ./define.h
make -C /lib/modules/3.6.1-gentoo/build/ SUBDIRS=/mnt/rts_bpp modules
make[1]: Entering directory `/usr/src/linux-3.6.1-gentoo'
  CC [M]  /mnt/rts_bpp/rtsx.o

  CC [M]  /mnt/rts_bpp/ms.o
  LD [M]  /mnt/rts_bpp/rts_bpp.o
  Building modules, stage 2.
  MODPOST 1 modules
  LD [M]  /mnt/rts_bpp/rts_bpp.ko
make[1]: Leaving directory `/usr/src/linux-3.6.1-gentoo'


Code:

# make install
cp rts_bpp.ko /lib/modules/3.6.1-gentoo/kernel/drivers/scsi -f


Code:
# depmod


[2] But as a result, after rebooting computer there is no driver:
Code:
# lspci -v

[3] What I realized, from the Gentoo-kernel 3.6.0 & 3.6.1 there is some difference in /lib64/modules after installing driver:

Code:
# ls -la /lib64/modules/
total 28
drwxr-xr-x  7 root root 4096 Oct  8 22:35 .
drwxr-xr-x 11 root root 4096 Oct  8 19:12 ..
drwxr-xr-x  6 root root 4096 Aug 27 22:32 3.5.2-gentoo

drwxr-xr-x  6 root root 4096 Oct  8 22:32 3.6.1-gentoo


For 3.5.4 we have scsi folder, and there is a driver:
Code:
# ls -la /lib64/modules/3.5.4-gentoo/kernel/drivers/
total 24
drwxr-xr-x 6 root root 4096 Sep 18 09:32 .

drwxr-xr-x 2 root root 4096 Sep 18 09:42 scsi
drwxr-xr-x 3 root root 4096 Sep 18 09:32 staging


Code:
# ls -la /lib64/modules/3.5.4-gentoo/kernel/drivers/scsi/
total 452
drwxr-xr-x 2 root root   4096 Sep 18 09:42 .
drwxr-xr-x 6 root root   4096 Sep 18 09:32 ..

-rw-r--r-- 1 root root   2991 Sep 18 09:32 scsi_wait_scan.ko


For Gentoo kernels 3.6.0 & 3.6.1 there is scsi file instead of scsi folder:
Code:
# ls -la /lib64/modules/3.6.0-gentoo/kernel/drivers/
total 460
drwxr-xr-x 5 root root   4096 Oct  6 15:53 .

-rw-r--r-- 1 root root 448862 Oct  6 16:03 scsi
drwxr-xr-x 3 root root   4096 Oct  3 20:43 staging


Code:
# ls -la /lib64/modules/3.6.1-gentoo/kernel/drivers/
total 460
drwxr-xr-x 5 root root   4096 Oct  8 22:32 .
drwxr-xr-x 5 root root   4096 Oct  8 22:28 ..
drwxr-xr-x 3 root root   4096 Oct  8 22:28 char
drwxr-xr-x 3 root root   4096 Oct  8 22:28 net
-rw-r--r-- 1 root root 448862 Oct  8 22:32 scsi
drwxr-xr-x 3 root root   4096 Oct  8 22:28 staging


All I did for installations rts_bpp driver for those 2 kernels (3.6.0 & 3.6.1) was the same like for many others kernels before:
Code:

# make install
cp rts_bpp.ko /lib/modules/3.6.1-gentoo/kernel/drivers/scsi -f


So whats wrong? Why I have scsi file instead scsi folder in those new kernels? Bellow header listing of this starnge scsi file:
Code:
ELF Header:
  Magic:   7f 45 4c 46 02 01 01 00 00 00 00 00 00 00 00 00

Err, the basics of the shell: You're copying the file "rts_bpp.ko" to a file called "scsi".

It did work for the last few kernels:
Code:
# make install
 cp rts_bpp.ko /lib/modules/3.6.1-gentoo/kernel/drivers/scsi -f


Maybe because there was no scsi folder, so option -f (for cp) made a scsi file (instead of coping this file inside scsi folder)
Code:
-f, --force
              if an existing destination file cannot be opened, remove it and try again (redundant if the -n option is used)


Anyway, I did manually scsi folder, did
Code:
# make install
 cp rts_bpp.ko /lib/modules/3.6.1-gentoo/kernel/drivers/scsi -f

again. I have got scsi folder and there is a driver inside scsi:
Code:
# ls -la /lib64/modules/3.6.1-gentoo/kernel/drivers/
total 24
drwxr-xr-x 6 root root 4096 Oct  9 11:16 .
drwxr-xr-x 5 root root 4096 Oct  8 22:28 ..
drwxr-xr-x 3 root root 4096 Oct  8 22:28 char
drwxr-xr-x 3 root root 4096 Oct  8 22:28 net
drwxr-xr-x 2 root root 4096 Oct  9 11:16 scsi
drwxr-xr-x 3 root root 4096 Oct  8 22:28 staging


Code:
# ls -la /lib64/modules/3.6.1-gentoo/kernel/drivers/scsi/
total 448
drwxr-xr-x 2 root root   4096 Oct  9 11:16 .
drwxr-xr-x 6 root root   4096 Oct  9 11:16 ..
-rw-r--r-- 1 root root 448862 Oct  9 11:16 rts_bpp.ko



UPDATE

OK It works.
Code:
[code]# make install
 cp rts_bpp.ko /lib/modules/3.6.1-gentoo/kernel/drivers/scsi -f[/code]

The problem is if there is no scsi folder, so comannd above (make install) is creating scsi file instead of coping a driver inside /scsi file.
So after manually creating scsi folder, did make install again, depmod and everything works fine.

So Gusar,
should it be a
Code:
cp rts_bpp.ko /lib/modules/3.6.1-gentoo/kernel/drivers/scsi/ -f

instead of
Code:
cp rts_bpp.ko /lib/modules/3.6.1-gentoo/kernel/drivers/scsi -f
