Nope,this one is correct :

# edid-decode /sys/class/drm/card0-HDMI-A-1/edid

 

[covacat]

in ./edk2-rockchip/Silicon/Rockchip/Rk356x/Drivers/DisplayDxe/DwHdmi.c

     switch (PixelClock * 10) {
     case 594000:
     case 297000:
     case 148500:
     case 74250:
+    case 44000:
+    case 27000:

     for (NumExt = 0; NumExt < MIN (MAX_EDID_EXTENSION_BLOCKS, Buf[126]); NumExt++) {
-        Status = DwHdmiEdidRead (1 + NumExt, &Buf[128 + (1 + NumExt)], 128);
+        Status = DwHdmiEdidRead (1 + NumExt, &Buf[128 * (1 + NumExt)], 128);
         if (Status != EFI_SUCCESS) {
             break;
         }
     }

add this mods and it should support edid detection; the board should work on boh the big and small display in their native resolution

i was wandering if it works now in freebsd. the /sys/class/drm is a linux thing

you should be more clear here. I don't understand if the previous changes should be applied or not.

 

[covacat]

the lines that begin with + should be added and the ones with '-' removed
do not add the '+' symbol, only the rest of the line
first is about line 140 and the other at 320

 

[ZioMario]

The changes below should be applied together with your last one,or the last one is enough and the changes that I have remembered below should be ignored ?

1) change the values here :

https://github.com/jaredmcneill/qua...ckchip/Rk356x/Drivers/DisplayDxe/DisplayDxe.c

with these ones :

/* Fallback to 720p when DDC fails */
STATIC HDMI_DISPLAY_TIMING mDefaultTimings = {
.Vic = 0,
.FrequencyKHz = 44000,
.HDisplay = 720, .HSyncStart = 820, .HSyncEnd = 900, .HTotal = 976, .HSyncPol = FALSE,
.VDisplay = 720, .VSyncStart = 738, .VSyncEnd = 742, .VTotal = 754, .VSyncPol = TRUE,
};

2)

in DwHdmi.c at DWHDMI_MPLL_CONFIG mDwHdmiMpllConfig[] = {

add this the second line

{ 46000, 0x00b3, 0x0000, 0x0000 },

between the { 40000... line and the { 65000 ....line

and rebuild

3)

in ./edk2-rockchip/Silicon/Rockchip/Rk356x/Library/CruLib/CruLib.c

at STATIC CRU_PLL_RATE CruPllRates[] = {

delete all the array definition and replace it with this :

together with the previous ones
if it works after this last one with both screens then the one with the screen data can be reverted to original (ie fall back to 720p if edid fails). so the image will be usable on a more std screen that the 720x720

 

[ZioMario]

pkg install falkon-qtonly

With it I can see the youtube videos,but the flow is slow and jerky. Not acceptable. Thanks anyway for the suggestion.

 

[Phishfry]

Have you checked the frequency of your cores? Check to see..
sysctl dev.cpu.0.freq
How does top look for memory usage? gstat your disk usage.
Find the bottleneck.
scfb driver setup?

 

[ZioMario]

pkg install falkon-qtonly

This is the best performance that I can achieve from a browser ?

 

[Phishfry]

Single video stream from u-tube should be possible on scfb. It works on x86.

Have you seen any progress on Rockchip DRM driver for FreeBSD? That should help. There are hardware features here.

Where ?

 

[Phishfry]

The qtonly flavor is what I prefer. I do not run a KDE desktop so I want minimal dependencies.

[ZioMario]

Nice. How many chances there are that I will get the hardware acceleration on my Radxa 3W using one of those drivers ?

 

[Phishfry]

Well the article does mention RK3399. So for desktop features that is probably what you need.

I really have not heard of anybody using panfrost drivers on FreeBSD. Interesting.

 

[ZioMario]

One idea that is intriguing me is to use the version of Firefox bundled with the tor-browser package. I see that it is a little bit old,but fast. Not sure if I can use it without connecting to the tor network...

[Phishfry]

Patches from a four year old article could be troublesome.

You need to bounce patch against code and see if it is already committed.

 

[Phishfry]

So dig around newer source tree and look at
/usr/src/sys/dev/drm

There used to be a i915drm driver in base but it was pulled out and sent to ports. So I don't know if all DRM was removed or what. It helps to know history.

Start digging into source. It is not easy but needed. Research the code commitals for the /drm directory.

Thanks. I know that you hate to read this,but I don't know where to start. This is too advanced for me.

 

[Phishfry]

A cursory check of that directory would tell you it is gone.

It is now named drm2

What this means ? that I should not install it because it has been merged inside the main code ?
