Custom Kernels

[Jamie]

Jamie,

have you had a chance to look at the 9.3 release? Has its kernel changed?

Source hasn't been posted yet for the tivo 9.3 linux kernel. 9.1 and 9.2 were little changed from 8.x.

I recently had my TivoHD PROM'd and then I used the Gen06 Custom 8.1.7 Kernel to setup my customizations. I've applied the superpatch and somewhere along the way I lost the ability to see my TTCB Service.

Is this to be expected ?
Is there a problem with TTCB and Hack'd Tivos ?

I don't see what the discussion at the link you provided has to do with the OPs problems.

I don't see what the discussion at the link you provided has to do with the OPs problems.

The OP couldn't transfer from PC to tivo (TTCB). The referenced link discusses how the certificate used for TTCB has expired, and the feature will stop working unless you upgrade to the newer version of TiVoDesktop. Since the OP was having trouble with TTCB, it seems possible he's just run into this issue.

In any case, this is a FILES forum thread and discussion really doesn't belong here. I guess I never should have responded to any posts in this thread. Let's move discussion elsewhere.

I was having a look around the other day, and I notice that dynamic.tivo.com/linux is different from www.tivo.com/linux. For one thing www.tivo.com/linux has 9.3 kernel source listed.

I will probably have a go at building my own 9.3 kernel when i recover from work this week.

Here are custom Gen05 and Gen06 kernels built from the 9.4.1 tivo kernel sources. Be sure to read and understand the first post in this thread before attempting to us these custom kernels.

Like the stock 9.4 tivo kernels, these have the usbcore and host modules built into the kernels.

An additional patch is include here that changes some 32 bit ints in the tivo ide-disk.c driver to 64 bit ints. This allows the kernel to work with partitions > 1TiB. Without this patch, you'll get "kernel: idedisk_dosectors: Access beyond end of drive" errors with partitions > 1TiB. Note that there is still a 2TiB partition size limit imposed by the ancient apple partition table format the tivo still used.

The plain vmlinux-Gen0{5,6} kernels are built with the stock kernel tivo config options and no extras beyond the patch above.

The vmlinux-Gen0{5,6}-netopt-ext3 kernels have my favorite custom kernel extras: netfilter turned off, ext3 file system turned on, etc. You'll need to replace iptables if you use these kernels, as discussed in the first post in the thread. You'll also need to replace the stock bcmenet.o with the versions here.

Toolchain and kernel build scripts are also included. I tested these on both linux (fedora 10) and cygwin. On cygwin, you need to use a "managed mount" when you build the toolchain to work around the fact that NTFS is case insensitive.

Gen06.tar.bz2 works like a champ on my prom hacked TiVoHD.

Thanks Jamie!

Will the lastest builts ("Gen05-netopt-ext3...kernels built from the 9.4.1 tivo kernel sources") work with v11 software?


So does bcmenet.o go to /lib/modules/ or /platform/lib/modules ?

Yes.

Replace the original, in /platform/lib/modules. It's probably a good idea to rename the original so you have it in case there is any problem.

Sweet. Will do.
Thank you for a quick response and of course the actual kernels.

I am using you Gen06-netopt-ext3.tar.bz2 kernal.
The system rebooted on its own. This is repeating in the kernal log before the reboot. Any ideas on what is causing this?

Thanks

Is it in a reboot loop, or was it a onetime reboot? The kernel works fine on my THD. It's been up for more than 30 days without a reboot on 11.0 with that kernel.

As near as I can tell, those messages aren't coming from the kernel or kernel modules, they are coming from /platform/lib/libhpk.so, linked into tivoapp.

PCR messages look signal source related to me. PCR: "Program Clock Reference"; TS: "Transport Stream"? Perhaps your signal source is bad?

[T_RJ]

it is not in a reboot loop just those were the messages just before it rebooted. I think you are correct about the signal source my OTA antena was not connected

Thanks

I'm getting about 50mbps with vmlinux-Gen05-netopt-ext3 kernel.
Both with using patched mfs_ftp.tcl or tserver.
Jamie you mention that you achieved speeds of 90mbps, based on netpref numbers. Are those numbers different than a practical download speed? Or is something special required?
