Hi Jani,

I was able to update my = kernel to 4.6 which has the DRM_DP_AUX_CHARDEV in the Kconfig file lin= ux-4.6\drivers\gpu\drm. Though I also add DRM_DP_AUX= _CHARDEV=3Dy in
<= /span>

How can I verif= y the DRM_DP_AUX_CHARDEV takes effect or got configure it correctly?=

It still unclear to me ho= w to follow what you mean by using DRM DP AUX interface and getting /dev/dr= m_dp_auxN node(s) that allows me to read and write arbitrary DPCD offsets.&= nbsp;

Please have comments and advice.

Regards,=

John

Hi Jani,

Good day!

Thank you for taking the time to poi= nt out those information. It=E2=80=99s a great help to me.

Also apologies for the late reply, your first reply= went to my spam inbox, not sure what happen and I was waiting for replies = for days.

I'm= still new to Linux and to DRM. I also need to investigate and learn more a= bout it.

Here= 's what I have done so far. I was able to work on the modeprint test applic= ation from the libdrm package found in the website github.com/gr= ate-driver/libdrm. I need to understand how user space and kernel works and= modeprint provided me a simple understanding how it works.

The modeprint requires a module name to open and I provi= ded the i915 module. It followed opening the device name then calling ioctl= commands to get resources, drm mode get connectors, encoders and crtc. Fro= m here, i was able to detect the display device's information successfully.=

So from here I got stuck and got confused. I only notice that in th= e drm.h it has limited IOCTL commands which it doesn't reach what i needed = like to reach scope in drm_dp_helper.c or intel_dp.c = where the dp aux read/write functions.

<= span>

Okay, back to your advice. Correc= t, I'm trying to access DPCD from the userspace. I haven't tried it and I'm= not sure how it will goes out. I will try it now and I will give feedback = on this.

From what I understand, I need to rebuild the= entire kernel with modification to Kconfig file (depends on DRM=3Dy) in linux-4.16= \drivers\gpu\drm directory. Then expect /dev/dr= m_dp_auxN node in the system.

config DRM_DP_AUX_C= HARDEV

=09bool "DRM = DP AUX Interface"

=09depends on DRM=3Dy

=09help

=09 Ch= oose this option to enable a /dev/drm_dp_auxN node that allows to

=09 read and write valu= es to arbitrary DPCD registers on the DP aux

=09 channel.

The second advice, I guess your correct since the display device i= needed to communicate is under Connector: DP-1 and not in Connector: eDP-1. This is based on the application modeprint result.

Regards,

John

Let me double check, you're talking a= bout doing DPCD access from
userspace? The *only* interfa= ce that can be recommended for that is the
DRM DP AUX int= erface. If you have kernel config DRM_DP_AUX_CHARDEV=3Dy,
you'll get /dev/drm_dp_auxN node(s) that allows you to read and write
arbitrary DPCD offsets. It's a chardev; you can use e.g. dd t= o debug
read DPCD.

O= f course, it would be better to have a generic backlight interface for
DPCD based backlight in kernel. We have the basics for that f= or Intel
GPU in i915/intel_dp_aux_backlight.c. Granted, i= t should be moved to
common DRM code, but it also doesn't= work for you if you have the chip
connected to regular D= P. It expects eDP, and somewhat spec compliant eDP
DPCD b= acklight support.

HTH,
Jani.

Hi Jani,

I can now see /dev/drm_d= p_aux*.

I'm not familiar with dd command.Correct m= e if I'm wrong.

Possible commands i tried and noth= ing happen:

dd if=3D/dev/drm_dp_aux1 seek=3D723 ibs=3D2

dd of=3D/dev/drm_d= p_aux1 seek=3D723 ibs=3D2

dd if=3D/dev/drm_dp_aux2 seek=3D723 ibs=3D2

dd of=3D/dev/drm_dp_aux2 seek=3D723 = ibs=3D2

I assumed I could read the= brightness msb and lsb using the define in drm_dp_helper.h.

#define DP_EDP_BACKLIGHT_BRIGHTNESS_MSB 0x722=

#define DP_EDP_BACKLIGHT_BRIGHTNESS_LSB 0x723=

From here, I was thinking if I could try to open = \dev\drm_dp_aux* then read the brightness offset 0x723, though not sure how= to proceed with it.

I was able to successfully open \dev\drm_dp_= aux1 and \dev\drm_dp_aux2 but I thinking I'm wrong when I proceed to ioctl = because they all failed.

#define BR= IGHTNESS 0x723

int main(int argc, char ** argv)

{

int fd;

int retcode;

= char out[128];

if((fd =3D op= en("/dev/drm_dp_aux1",O_RDWR)) >=3D0)

{

= ; printf("open success");

}

else

{

printf("open failed");

&= nbsp; }

if((retcode =3D ioctl(fd,BRIGHTNESS,&out)) < 0)=

{

printf("ioctl fail= ed");

}

<= div style=3D"color: rgb(0, 0, 0); font-family: "Helvetica Neue", = Helvetica, Arial, sans-serif; font-size: 10px;"> else

if((fd =3D open("/dev/drm_dp_aux2",O_RDWR)) >=3D0)

{

printf("open success");

}

else

{

printf("open failed");

}

Boot the kernel, run 'ls /dev/drm_dp_aux*'. If you see stuff, you= got it

Hi Jani,

I seek 0-800 and here's = what I get, all 11 0A in hex. Not sure if this is the brightness value of t= he display. I also did a test, when I disconnect the DP to the display and = execute the dd commands, it would say error reading 'dev/drm_dp_aux1': Conn= ection timed out. So I think my display setup is okay and the 11 0A values = are really coming out from the display.

Output in hex:

11 0A 11 0A 11 0A 11 0A 11 0A 11 0A 11 0A 11 0A 11 0A 11 0A 11 0A 1= 1 0A 11 0A 11 0A 11 0A 11 0A 11 0A 11 0A 11 0A 11 0A 11 0A 11 0A 11 0A 11 0= A 11 0A 11 0A 11 0A 11 0A 11 0A 11 0A 11 0A 11 0A 11 0A 11 0A 11 0A 11 0A 1= 1 0A 11 0A 11 0A 11 0A 11 0A 11 0A 11 0A 11 0A 11 0A 11 0A 11 0A 11 0A ....=

You're mixing hex = and decimal numbers, you should probably use bs=3D1
count= =3D2, dd outputs binary so you probably need to pipe it to hexdump to
see anything, etc. Perhaps start experiments with reading at s= eek=3D0.

It's a character device, open, seek, read/write. Don't try any ioctls onit.

Good luck.

Hi Jani,

Thanks for the help. I was able to= manage your advice on the drm_dp_aux_chardev. Though I still need to learn= more about the DRM vs kernel process flow. Like for example, upon changing= /adding DRM_DP_AUX_CHARDEV in kernel .config, How did DRM_DP_AUX_CHARDEV wa= s being invoke here? From the code, I notice character device will be creat= ed under drm_dp_aux_register_devnode method.

For example I made two kernel 4.6 = with DRM_DP_AUX_CHARDEV=3Dy and another kernel 4.6 with DRM_DP_AUX_CHARDEV= =3Dn.

So the steps was to build and install the kernel with DRM_DP_AUX_CH= ARDEV=3Dy. Once finish, I tried to reboot and verified the /dev/drm_dp_aux_= chardev* and it was there. Now, I will change the .config DRM_DP_AUXCHARDEV= =3Dn then follow the steps below to manual build the DRM module. I'm not re= ally sure if I'm correct on this one.

1. rm /dev/drm_dp_aux_chardev*

2. make modules_prepare

3. make SUBDIRS=3Dscripts/mod

4. make SUBDIRS=3Ddrivers/gpu/drm modules

5. cp drivers/gpu/drm/i915/i915.ko /lib/modules/4.6.0-94.11-defau= lt/kernel/drivers/gpu/drm

6. ... I copy al= l .ko under drm to the lib/modules/4.6

7. = depmod

8. modprobe i915

9. ... I also modprobe all modules

10. reboot

The result was /dev/drm_dp_aux_chardev* was still there. My expecta= tion was it would disrepair or remove.

Please have comments and advice.

Regards,

John

Why are you disabling it = again? Just enable the config, use the

Don't do this. I don't und= erstand what you're trying to do.

Try 'git grep DRM_DP_AUX_CHARDEV' in your kernel git repo, and see how it affects conditional compilation. This list isn't kernel development 101. You still didn't say what your end goal is. Forget everything about DP AUX and the chardev and so on, just tell us what you're trying to achieve. Maybe you're asking about X, but you really want to know about Y.

Hi Jani,

The end goal was already ach= ieve by the advice you gave the DRM_DP_AUX_CHARDEV.

I just like t= o extend my knowledge into DRM such as a scenario having a kernel version t= hat doesn't have the DRM_DP_AUX_CHARDEV yet. Would it possible to implement= specific DRM_DP_AUX_CHARDEV to it.

Try 'git grep DRM_DP_AUX_CHARDEV' in your= kernel git repo, and see how
it affects conditional comp= ilation.
