 Posted: Fri Dec 14, 2018 7:44 am Post subject: How to get DAHDI working with kernel 4.19 |
 |
|
UPDATE
Following on:
| Code: | # uname -r
4.19.57-gentoo |
| Code: | cd /tmp
wget https://downloads.asterisk.org/pub/telephony/dahdi-linux-complete/releases/dahdi-linux-complete-3.0.0-rc1+3.0.0-rc1.tar.gz
tar -xf dahdi-linux-complete-3.0.0-rc1+3.0.0-rc1.tar.gz
cd dahdi-linux-complete-3.0.0-rc1+3.0.0-rc1/linux/
mkdir drivers/staging
cp -fR /usr/src/linux/drivers/misc/echo drivers/staging
sed -i "s|#obj-m += dahdi_echocan_oslec.o|obj-m += dahdi_echocan_oslec.o|" drivers/dahdi/Kbuild
sed -i "s|#obj-m += ../staging/echo/|obj-m += ../staging/echo/|" drivers/dahdi/Kbuild
echo 'obj-m += echo.o' > drivers/staging/echo/Kbuild
|
I could not build 3.1.
drivers/dahdi/wctdm.c was missing, which was needed for my TDM400P.
So I downloaded the old version:
| Code: | cd /tmp
wget https://downloads.asterisk.org/pub/telephony/dahdi-linux-complete/releases/dahdi-linux-complete-2.11.1-rc1+2.11.1-rc1.tar.gz
tar -xf dahdi-linux-complete-2.11.1-rc1+2.11.1-rc1.tar.gz
cp dahdi-linux-complete-2.11.1-rc1+2.11.1-rc1/linux/drivers/dahdi/wctdm.c dahdi-linux-complete-3.0.0-rc1+3.0.0-rc1/linux/drivers/dahdi/ |
And added in the required lines:
| Code: | # grep DAHDI_WCTDM dahdi-linux-complete-3.0.0-rc1+3.0.0-rc1/linux/drivers/dahdi/{Kconfig,Kbuild}
Kconfig:config DAHDI_WCTDM
Kconfig:config DAHDI_WCTDM24XXP
Kbuild:obj-$(DAHDI_BUILD_ALL)$(CONFIG_DAHDI_WCTDM) += wctdm.o
Kbuild:obj-$(DAHDI_BUILD_ALL)$(CONFIG_DAHDI_WCTDM24XXP) += wctdm24xxp/
|
I could then
| Code: | cd /tmp/dahdi-linux-complete-3.0.0-rc1+3.0.0-rc1/linux
make
make install
reboot |
| Code: | # lsmod | grep -E 'oslec|dahdi'
dahdi_echocan_oslec 16384 2
echo 16384 1 dahdi_echocan_oslec
dahdi 221184 4 wctdm,dahdi_echocan_oslec
crc_ccitt 16384 1 dahdi

I'm going to res this old thread only because somebody will find this useful and there's no other place on the webs that I could find anyone posting this.
To make wctdm working with DAHDI 3.1.0 the following changes need to be made in addition to the changes posted by @Fog_Watch
file: wctdm.c
line: 1135
< DAHDI_IRQ_HANDLER(wctdm_interrupt)
> static irqreturn_t wctdm_interrupt(int irq, void *dev_id)
line: 2853
< res = dahdi_pci_module(&wctdm_driver);
> res = pci_register_driver(&wctdm_driver); |

| Code: | # uname -r
4.19.82-gentoo
|
| Code: | cd /tmp/
wget https://downloads.asterisk.org/pub/telephony/dahdi-linux-complete/releases/dahdi-linux-complete-3.1.0+3.1.0.tar.gz
tar -xf dahdi-linux-complete-3.1.0+3.1.0.tar.gz
cd dahdi-linux-complete-3.1.0+3.1.0/linux
mkdir drivers/staging
cp -fR /usr/src/linux/drivers/misc/echo drivers/staging
sed -i "s|#obj-m += dahdi_echocan_oslec.o|obj-m += dahdi_echocan_oslec.o|" drivers/dahdi/Kbuild
sed -i "s|#obj-m += ../staging/echo/|obj-m += ../staging/echo/|" drivers/dahdi/Kbuild
echo 'obj-m += echo.o' > drivers/staging/echo/Kbuild
|
Include wctdm.c:
| Code: | cd /tmp
wget https://downloads.asterisk.org/pub/telephony/dahdi-linux-complete/releases/dahdi-linux-complete-2.11.1-rc1+2.11.1-rc1.tar.gz
tar -xf dahdi-linux-complete-2.11.1-rc1+2.11.1-rc1.tar.gz
cp dahdi-linux-complete-2.11.1-rc1+2.11.1-rc1/linux/drivers/dahdi/wctdm.c dahdi-linux-complete-3.1.0+3.1.0/linux/drivers/dahdi/
|
| Code: | # grep DAHDI_WCTDM dahdi-linux-complete-3.1.0+3.1.0/linux/drivers/dahdi/{Kconfig,Kbuild}
dahdi-linux-complete-3.1.0+3.1.0/linux/drivers/dahdi/Kconfig:config DAHDI_WCTDM
dahdi-linux-complete-3.1.0+3.1.0/linux/drivers/dahdi/Kconfig:config DAHDI_WCTDM24XXP
dahdi-linux-complete-3.1.0+3.1.0/linux/drivers/dahdi/Kbuild:obj-$(DAHDI_BUILD_ALL)$(CONFIG_DAHDI_WCTDM) += wctdm.o
dahdi-linux-complete-3.1.0+3.1.0/linux/drivers/dahdi/Kbuild:obj-$(DAHDI_BUILD_ALL)$(CONFIG_DAHDI_WCTDM24XXP) += wctdm24xxp/
|
Edit wctdm.c:
| Code: | cd dahdi-linux-complete-3.1.0+3.1.0/linux/drivers/dahdi/
# sed -n -e 1135p -e 2852p wctdm.c
static irqreturn_t wctdm_interrupt(int irq, void *dev_id)
res = pci_register_driver(&wctdm_driver);
|
Build:
| Code: | cd /tmp/dahdi-linux-complete-3.1.0+3.1.0/linux/
make
make install
reboot
|
| Code: | hostname ~ # asterisk -rx "dahdi show version"
DAHDI Version: 3.1.0 Echo Canceller: OSLEC

| This all helped me! I am OpenSuse and hit the issues where the TDM400P is no longer supported with DAHDI 3. So I made the changes you all supplied, built and installed the drivers and all worked. So thanks again. |

The above works for 5.4. In addition the following change is needed.
file: tmp/dahdi-linux-complete-3.1.0+3.1.0/linux/include/dahdi/kernel.h
line: 62
< #include <linux/pci-aspm.h>
> #include <linux/pci.h>
| Code: | # uname -r
5.4.38-gentoo
|
| Code: | # asterisk -rx "dahdi show version"
DAHDI Version: 3.1.0 Echo Canceller: OSLEC
