Next firmware tree is now 3.10

[dom]

The 3.10 kernel is to have long term support:
http://www.kroah.com/log/blog/2013/08/0 ... -3-dot-10/

(The last long term kernel was 3.4, so they don't come along very often).

I'm aiming to move to 3.10 for the main firmware, but initially I've moved the "next" tree to 3.10 first.
If no problems emerge in the next month, the default tree will move to 3.10.

To update:

Code: Select all

sudo BRANCH=next rpi-update

Note: this tree is aimed at testers. There could be missing kernel modules, or things that don't work.
If you find any problems, then report here, or create a github issue.

As I understand it, running dist-upgrade will fetch the kernel 3.6.11 with SD Card timeout and other fixes which was previously only available with rpi-update?

The apt-get repo is unrelated to this thread. There is a (3.6.11) apt-get update expected, but I'm not sure if it is out yet.

I am missing f2fs support. 3.9.11+ next branch had it.

Good point. That should be enabled.

Last time I tried the 3.10 kernel there were problems with the spi modules staying loaded, has this been addressed/fixed ?

Is there an issue reported for this?

I don't personally use SPI, and the driver came from the community.
I'm sure it can be fixed, but will need some help from someone who uses SPI and can explain exactly what goes wrong.

[Dilligaf]

Boblight uses the spi modules. What I was seeing was when modprobing the spidev module it would create /dev/spi* and then unload rather then staying loaded.
You could then see /dev/spi* but if you ran lsmod the modules weren't loaded.

next tree is updated. Added various requested options: F2FS, BATMAN_ADV, OPENVSWITCH, NF_NAT, DUMMY, QFMT_V1, QFMT_V2, DLM, joystick

Hi dom

So I jumped the gun and installed 3.10.13+

One thing I see where something's off: the calibration of the delay loop during the kernel init gives a very weird figure:

Code: Select all

[    0.000000] Switching to timer-based delay loop
[    0.001159] Calibrating delay loop (skipped), value calculated using timer frequency.. 2.00 BogoMIPS (lpj=10000)

Taken from /var/log/dmesg - also visible in /proc/cpuinfo. I know the "BogoMIPS" value is pointless, but it should actually calibrate to a figure close to the actual clock frequency of the CPU core.

The good news is that the weird dwc_otg USB resets are gone when there's a external USB hard drive attached, in my case auto-mounted through usb-mount, during system boot. In the latest 3.6.11+ (from a few days ago) it started acting up that way - it would stall for a moment, throw 1-2 dwc_otg resets, and then mount the drive - but 3.10.13+ is fine in this regard.

EDIT1: Another thing to note is that overall network throughput seems to have improved:

Code: Select all

scp testfile_250MB.img pi@raspberrypi:/dev/null
testfile_250MB.img   100%  237MB   4.2MB/s   00:57

Started off at 5.9MB/s and then stabilized at 4.2MB/s during the course of the file transfer.

Doing the same thing on the 3.6 series kernel, as shipped with the default Raspbian image, resulted in 2.5/2.7MB/s max. Still not at the ~10.2MB/s my BBB manages to achieve, but at least it's some improvement. /EDIT

EDIT 2: After copying another test file via Samba to the USB hard drive: same result ... flows at ~4.2MB/s - AND - the "sms95xx 1-1,1:1.0: eth0: kevent 2 may have been dropped" errors in the logs are also gone; 3.6 was happily throwing them out in quanities./EDIT

If I happen to find something else I'll drop you a note.

DOH! Should've checked the GitHub issue tracker first.
Thanks, my bad for not checking first.

[DavidS]

Just because someone decides to redifine something in a way that breaks some things does that mean that we should follow suite? There are many applications that rely on the empty loop bogomips figure to calibrate there delay loops where an active delay is required, or some that were written before there was reliable high resolution timing in the Linux Kernel (that did not come until Kernel version 2.4).

So I would vote for using the old form of bogomips.

[CommanderROR]

This might be an incredibly stupid question, but is the HDMI audio support for up to 192k included in this branch? Would be nice if the Pi stopped downsampling everything to 48KHz.
Picoreplayer and Raspify have this integrated and it seems to work fine...apparently all it takes is a small change to the bcm module.

@dom: Long-uptime issue detected ...

Kernel is 3.10.15+, uptime is ~3d 20m

I'm seeing random network drop-outs. Problem is not related to the power supply (already checked voltages, testpoints show me 4.98V (which isn't that far off the ~5.08V un-loaded output of the USB "charger")) and the network switch to which the Pi is connected is as good as new (Netgear GS108E, only a few days old) and works perfectly as I have no link issues on any other device that's connected to the switch.

Checking back through the logs, the drop-outs weren't there with 3.10.13+

So, you got a new network switch a few days ago and the link starts to drop?

You should do an rpi-update to an older version and check that the issue still exists.
Try a sudo rpi-update 7d605b7bf162fd4a9151804b2dcbd4d6e4b671d4.

So, you got a new network switch a few days ago and the link starts to drop?

Yes, I replaced a old 24-Port Netgear Gigabit switch with 2 Netgear GS108E (8-Port, Managed) switches because the 24-port switch was acting up. After closer inspection I found out the issue was caused by a couple of 1000µF 10V caps spread across the motherboard manufactured by CapXion (*RIPS HAIRS OUT*) - though all the other caps are from Taicon (belongs to Nichicon). I'm still waiting for the spares to arrive (ordered Nichicon caps and kicked the CapXion crap out and beyond this Universe).

You should do an rpi-update to an older version and check that the issue still exists.
Try a sudo rpi-update 7d605b7bf162fd4a9151804b2dcbd4d6e4b671d4.

Okay, so I carefully investigated the systems connected to the switch (like I wrote above I actually got two, I'm focusing on the ones connected to the "GS108E-1"):

• AMD Phenom II X6 1100T rig (Gigabyte GA-870A-UD3, Onboard Realtek 8168 PCIe GbE NIC)
  Stable 1000Mbps link, no dropouts
• AMD FX8150 rig (Gigabyte GA-870A-UD3, Onboard Realtek 8168 PCIe GbE NIC)
  Same. Perfectly stable 1000Mbps link without dropouts
• <some TI Sitara based ARMv7 board from some competitor which is not allowed to be mentioned here>
  Perfectly stable 100Mbps link, no dropouts.
• TP-Link WR841N Router (Uplinked to the switch)
  No dropouts at LAN Port 1 recorded in the logs of the router (DD-WRT)

Since none of these four systems show ANY network issues I believe it is safe to assume the switch is working as intended without issues.

Now on to the Raspberry Pi (512MB rev. B)

I prepared three SD cards and I also exchanged the network cable past a "tried and tested" one:
1 with the "daily driver" setup (Raspbian 7, Kernel 3.10.15+, BTSync, Samba, SSH enabled, boot to command line)
1 copy of the "daily driver" image (same SD, directly dd sd -> img && img -> sd) with Kernel 3.10.13+
1 with the standard Raspbian 2013-09-25 image, only updated to 3.6.11+ from October 2nd

Results:
SD with the genuine, updated, Raspbian image shows network dropouts (only few minutes after booting)
SD with 3.10.15+ kernel shows network dropouts (first drop happened after ~42 minutes uptime).
SD with 3.10.13+ is stable so far. No dropouts in 2 hours.

Also monitored the voltage at the testpoints - doesn't drop below 4.98V (using a Agilent digital multivolt meter). The Raspberry is powered off a "tabtools" Universal USB charger providing a grand total of 2 Amps, and the last time I checked with a resistive dummy load the charger didn't break a sweat at drawing 2 amps straight.

EDIT: Mon Oct 14, 2013 ~7:05 pm
3.10.13+ also drops the link, but a lot more less than any other of the two setups... during the day it happened two times, and at the 2nd time (about an hour ago) it dropped down to negotiating only a 10Mbps link-speed. Funnily enough it's only the Pi acting up (and yes, I also already plugged it into another Port on the switch), all other systems on the switch are still perfectly fine.

Hi dom,

any chance to add the lirc_rpi module to next firmware tree? Its included in master, but not in next

Thanks & regards, ollo_rpi

Should be there in latest update.

I also miss w1-gpio and w1-therm
which are in master but not in next.
Needed for 1-wire temperature-sensor

Hello dom,

works so far (at least for me).

Thanks a lot

Cool. I'm expecting to bump normal rpi-update tree to 3.10 this weekend.

YAY!

So new rpi fw is coming?
I remember something related to dynamic memory split, is it stable now?can I activate it ?How?
