SHUB3 Puma Bug - TBB BQM Improvement
 
hi all ,

my shub3 rebooted last night and since then my tbb bqm graph is a lot better. Is there an actual fix for this issue that virgin have rolled out or is this new firmware just masking the issue and making the graph look 'pretty' for most users .

TIA

I see this also:

Ran a ping test form here: http://ping-test.net/ and seems much better:

1;"Ping Test: NL - Amsterdam";"30";"29";"25";"27";"27";"25";"27";"25" ;"26";"30";"28";"30";"27";"23";"26";"25";"24";"25" ;"33";"27";"24";"30";"31";"26";"26";"25";"26";"24" ;"24";"26";

Just so we all understand what has happened to the Hub 3, the code that handles ICMP packets (the BQM pings) has been shifted from the CPU (Puma 6) to one of the comms chips. At least that's my understanding. It makes the BQM look wonderful and does release the CPU to some extent to process the other protocols. However the periodic housekeeping interrupt still occurs. It could be classed as a cosmetic measure.

Ah. The VW fix. :D

What is this "periodic housekeeping interrupt" that for me keeps occurring about every 80-100mins? It seemed to disappear throughout today but has popped up again. Is it now happening less often?

It is the basic flaw of the Puma 6 and occurs every 20 to 30 seconds. The processor interrupts whatever protocol stuff it is doing in order to clear itself down having got too much to do and too little resource with which to do it.

The Puma 6 CPU is the Intel Atom 4100; a single core processor running at 1.4GHz. You couldn't get a cheaper version of Puma 6. And only single core. Displacement of the ICMP processing to the comms chip slightly improves the Puma 6's real data processing bandwidth but not to any significant extent.

The BQM is, to my mind, a false positive.

But .... it looks better :D

TBH, aside from the pings issue, I cannot say Ive really noticed any issues using the HUB3, my upload and download speeds have always been fine.

yeah, and I play fast paced fps every day and never have a problem



I have just had a look at the shub config to make sure nothing else untowards has happened and it looks like they have finally fixed some other stuff as well. A second table has been added in the downstream tab showing your pre and post-rs errors for each channel and in the upstream tab a second table has been added to show your T1, 2 3 and 4 timeouts for each channel. How long has it taken them?

Did the power levels get taken away, Mon General?

General Maximus 15-02-2018 09:50

Re: SHUB3 Puma Bug - TBB BQM Improvement
 
nope, they are still there and a second table has been added for the rs errors. You will note that the scroll bar is on the second half of the page. It is similar to the upstream screen shot you can see, it just can't all fit on one screen.

That is my take on this as well.

Our USA cousin's still have a Class Acttion lawsuit ongoing as far as I know against "Pumagate". Intel have done themselves no favours recently.
Hopefully the next gen cable modems will go back to Broadcom ?

You guys maybe on the firmware trial as people are reporting that they never signed up for it but still got it.

My Puma 6 test now looks normal on a wired pc compared to all the red before, although doing the same test via wifi on my android phone produces 100%
red so not sure what is happening there?

I havent signed up for anything. I wonder if they are in a second phase of testing. They have tested router mode shub on peeps and now they need to test it in modem mode with proper routers. They havent bothered asking because they know the type of people who buy quality stuff will say no.
