[reelbox] [eHD] Kernel Modul auf 64-bit portiert + reelbox-plugin funktionsfähig

pbrb · 9. Februar 2021

hat zufällig irgendjemand das eHD Kernel Modul (hdshm3) im stillen Kämmerchen auf 64-bit portiert? Nur eine Frage, bevor ich's nochmal probiere (hatte mal angefangen...such immer noch die Patches von damals...)

lnj · 9. Februar 2021

I did compilation without errors, but the module did not work, it seems to crash.

pbrb · 10. Februar 2021

at least I'm now on the similar level, module compiles (5.10.13 64-bit) and at least started to be loaded...will investigate further by enabling bunch of debug lines...

pbrb · 11. Februar 2021

the kernel module is now supporting 64-bit, get compiled and loaded (and also can be removed again...fixed a bug here) - many debug lines are currently added...

Potentially, still some bugs related to the shared structures are inside...but can't futher test currently, because "hdboot" is not detecting proper U-Boot of eHD:

Code

# hdboot -r -i linux.bin
Decypher PCI BAR1: 90000000
pcimap: called with offset=90000000
pcimap: result mmap base=0x7fb83fc26000
main: map bar1=90000000 to pci_base=0x7fb83fc26000
wait_for_pciboot: called
wait_for_pciboot: pci_base=0x7fb83fc26000 ffffffff
Warm Reset
upload_start: called with pci_base=0x7fb83fc26000
wait_for_pciboot: called
wait_for_pciboot: pci_base=0x7fb83fc26000 ffffffff
wait_for_pciboot: pci_base=0x7fb83fc26000 ffffffff
...
Timeout: U-Boot not ready for PCI boot

Looks like something is broken with the memory mapping of "BAR1" and the trigger of the reset and the detection of the magic pattern of a successful U-Boot is therefore not successful:

Code

        *(volatile int*)(pci_base+CCB_REG_CCBCTRL)|=1;
        *(volatile int*)(pci_base+CCB_REG_CCBCTRL)&=~1;
// warm reset set's SCRATCH_REG to 0
        *(volatile int*)(pci_base+SEM_3_SCRATCH_REG)=0;

// look for pattern, but result is ffffffff (should be at least 0 until pattern occurs)
if (*(volatile int*)(pci_base+SEM_3_SCRATCH_REG)==0xb001abcd)

Current code is in a branch available:

https://github.com/pbiering/Re…/src-reelvdr/utils/hdshm3

Potentially one can support me in fixing the memory mapping in hdboot.

BAR1 value is matching "lspci" output:

Code

lnj · 11. Februar 2021

I'll try this weekend.

pbrb · 11. Februar 2021

some update: after creating a failsafe check in the module code it turned out that the PCI memory was not accessable at all. After overtaking part of the code from a reference implementation, which enables the PCI device proper, the shared memory inside the module is working...but now "hdboot" can't access it anymore

Code

Decypher PCI BAR1: 90000000
pcimap: called with offset=90000000
Failed to mmap PCI (Operation not permitted)
main: pcimap returns pci_base=NULL

branch updated, will investigate further, but help is very welcome

eHD LED turned green - will continue...

futher progress, shmnetd successfully running (add also support to reelbox-control.sh), login to eHD successful:

Code

BusyBox v1.2.2 (2013.11.01-14:23+0000) Built-in shell (ash)

Welcome to extensionHD
This image is based on SDK V1.7.2.
It was built @ Пнд Май 22 00:17:03 VLAT 2017 on ua0lnjehd.

Next step is getting tftp up and running to serve "/hdplayer/hdplayer"

pbrb · 12. Februar 2021

Any idea where the MIPS SDK can be pulled? Where can I also find the framework to create an updated eHD boot image?

pbrb · 12. Februar 2021

original "hdplayer" is now loaded via tftp, hdcontrol tools are working, only
"hdtsplay" is still not showing anything.

I haven't found how to fix it yet.

pbrb · 12. Februar 2021

Makefile issue I have to look into separatly, but the other problem is caused by "hexint" module parameter, looks like at least your kernel header files have no support for it....

Branch update with a workaround, please try

just a new update, got reelbox3 plugin compiled, starts but crashes after some seconds...have to debug further but assume all fixable.

Alexandro77 · 13. Februar 2021

this will be another breakthrough. Great job.

Watching with interest.

pbrb · 13. Februar 2021

I made it....I have live TV withsound and can replay recordings - only one strange issue is on with still pictures during setting/shifting marks -> picture will turn into black...will publish adjusted sources next days have to check how organize the references proper.

lnj · 13. Februar 2021

I have works too.

vdr only, without xinelib yet.

vdr-2.5.1.

lnj · 13. Februar 2021

Do you know that the decoder from Micronas (firmware) is made on ffmpeg?

Do you know that the decoder from Micronas (firmware) is made on ffmpeg?

don't know.

here btw. the new repository with a readme file

https://github.com/pbiering/vdr-plugin-reelbox

the "utils" tree is kept outside, will push missing files next to

https://github.com/pbiering/Re…D-64bit/src-reelvdr/utils

-> wait 1 day....

lnj · 14. Februar 2021

Look at https://bitbucket.org/ua0lnj/r…06cdc578db6e22a5fb39965c3

thank you, applied.

I'm done, with new mainboard I have now 2 options for output device

reelbox plugin +eHD
- eHD kernel driver is buildable with akmods
- magic scripts got support
- related systemd files are also created
softhddevice plugin

Major TODOs now (too much for me)

improve OSD resolution support (currently it's SD-only and even LCARS is not really looking nice)
fix incompatibility with skindesigner (potentially depending on OSD resolution)
fix 1080p output problem (except hardware is not supporting at all)

Minor TODOs (will be done next)

add debug mask option to reelbox plugin to be passed to eHD related code
create RPM for vdr-plugin-reelbox
add udev file for eHD kernel module package
add some instructions to Wiki...
test with old mainboard in untweaked AVR II

[reelbox] [eHD] Kernel Modul auf 64-bit portiert + reelbox-plugin funktionsfähig

Jetzt mitmachen!
