Wifi is solid, CPU usage is low. Getting results consistent with everyone else with a 2x2 client on 80mhz wide channel (consistently the best openwrt r7800 wifi results I’ve seen).
Yes, that package is included as well
I've also upgraded to @Ansuel's firmware with latest commits and wifi is as solid and fast as before. Good work again!
@ansuel: May I ask you to try to support the C2600? I'd like to test it alongside my R7800. I tried changing the dtsi for the C2600 myself some time ago but I did not succeed.
Pushed a testing commit... Tell me if it does work... (if it doesn't I have to check the gpl source)
pretty bus for now with exams... can you remind me this the 6th nov?
It compiled ok. Does it mean it should work or not necessarily?
Thanks a bunch anyway and good luck with your exams (although with your genius it seems you don't need luck...)
we you should test it... i really don't know if it does work
It did not work. Thanks anyway!
can you give me the log?
Sure, just PM'd you. Thank you for checking on this.
from what i can see the wifi crash. Did you test if ethernet works?
It seemed like it did. After booting, I was able to access the router/luci via cable and even was able to upload a file in an attempt for a sysupgrade. It did upgrade but not correctly. Then I had to tftp it to recover.
Hi @Ansuel,
Got couple NSS FW Coredumps during the system bootup today.
I've setup pstore/ramoops to capture the kernel oops/panics by reducing available memory to 460M and setup pstore/ramoops after that.
Below relevant cat /proc/iomem part:
cat /proc/iomem
root@R7800:/# cat /proc/iomem
...
42000000-5e1fffff : System RAM
42208000-42bfffff : Kernel code

5e32a7f9-5e32aff8 : ramoops:ftrace(1/1)

Not sure whether these NSS FW core dumps are related to that pstore/ramoops setup but below are 2 separate core dumps I got today.

These are after fresh git clone master & your nss repo merge compilation today.

Edit 2:
I would consider the above Core dumps False Positive triggered by the earlier pstore/ramoops configuration.
- Without pstore/ramoops setup I don't have issues during reboot
- With the new adjusted pstore/ramoops setup I don't have issues during reboot

For whatever reason (most likely the point where I cut the RAM availability) NSS FW was not happy and was randomly crashing either during the reboot or after some time of uptime (max 1h). Other drivers/applications did not though triggered crashes.

Could you provide your cmdline argument for the kernel? I'm trying to set this up too on my r7800.

Hi qosmio,
Below related dmesg messages including the kernel command line arguments.
[ 0.000000] Kernel command line: mem=400M ramoops.mem_address=0x5BFFFFFF ramoops.mem_size=0x2C000 ramoops.record_size=0x4000
[ 0.020532] ramoops: using module parameters
[ 0.021017] pstore: Registered ramoops as persistent store backend
[ 0.021034] ramoops: using 0x2c000@0x5bffffff, ecc: 0
With above kernel cmdline parameters my R7800 seem to run now "normally" and system reports 409M total memory.
[ 0.000000] Memory: 394424K/409600K available
Notes:
- At least NSS FW seem to be sensitive where the available memory is cut. Can be platform memory management related but I'm not knowledgeable enough to be able to comment more.
- I changed the record_size from default 4k to 16k (
ramoops.record_size=0x4000). Record size should be a power of 2. - Be prepared to tftp working factory images + backup (without pstore/ramoops changes)
- in pstore setting I only selected below to keep it as simple as possible (removed the default selected deflate compression).

Thanks for this! Was banging my head over how to get it all working. The offsets were confusing and I tried various "memmap=1M!0", "memmap=1M@0", "memmap=1M$0" since I didn't know what regions to allocate initially. But this works. I slightly modified it to mem=419M that seems to be the maximum I could do before the NSS cores starting panicing.
I've also compiled in support for pstore_ftrace, but for obvious performance reasons, am only going to enable it during off hours. Hopefully I can capture full trace dump during off-peak hours with it enabled.
Good it works. Did several hours of fiddling with that mem parameter over the weekend but returned that 400M at the end of it.
Can you share your cat /proc/iomem for System RAM part as system is rounding the value defined with mem parameter?
Mine with mem=400M ends up for below that's the 409M seen by system?
42000000-5affffff : System RAM
A slight change. Had to reduce it to 415M. Even though it booted up fine, and showed in /sys/fs/pstore it wouldn't show up in /proc/iomem. So far everything's been stable with that size.
Here's the /proc/iomem:

mem=415M ramoops.mem_address=0x5BFFFFFF ramoops.mem_size=0x2C000 ramoops.record_size=0x4000
Total memory ends up being 402M
When I had it set to mem=400M the total reported was 380M.
Hi qosmio,
One thing to note is the ramoops starting address, ramoops.mem_address=0x5BFFFFFF that need to be beyond available System RAM end address or it will be cleared during the restart.
I selected that 0x5BFFFFFF without any logic just to be beyond the System RAM end address (0x5AFFFFFF) when selecting mem=400M.
42000000-5affffff : System RAM
That selected ramoops.mem_address=0x5BFFFFFF is actually starting at 425M.
If you want to try higher mem values I'd suggest to try to move mem_address at the end of the available RAM, something like ramoops.mem_address=0x5F000000 (starting at 475M).
R7800 System RAM is located at 0x42000000 - 0x5FFFFFFF without kernel cmdline mem parameter cutting it smaller.
ramoops.mem_address + ramoops.mem_size cannot be bigger than 0x5FFFFFFF.
I'll try that mem=415M/419M over the weekend as cannot do any changes during the working days.
