Feisty ships with OLD cx2341x mpeg encoder firmware

this affects all kernels 2.6.20 and after ... and priority should NOT be low on this..... any driver that depends on cx2341x.ko is BROKEN under ubuntu with this old firmware. new code needs the *official* firmware, please update asap.

dmesg output, using the bad firmware currently shipped by ubuntu:

[ 2363.688000] cx88[0]/2-bb: Firmware and/or mailbox pointer not initialized or corrupted
[ 2363.728000] cx88[0]/2-bb: ERROR: Firmware size mismatch (have 262144, expected 376836)
[ 2366.060000] cx88[0]/2-bb: Firmware and/or mailbox pointer not initialized or corrupted
[ 2366.100000] cx88[0]/2-bb: ERROR: Firmware size mismatch (have 262144, expected 376836)

...this is using cx88-blackbird. pvrusb2 and ivtv would report the same error.

This is also reported with more detail in https://bugs.launchpad.net/ubuntu/+source/linux-source-2.6.20/+bug/131464
for Feisty and https://bugs.launchpad.net/ubuntu/+source/linux-source-2.6.20/+bug/131464 for Gutsy. I didn't notice this bug until now when I was going to look for possible firmware related ivtv bugs.

I put the wrong link to the Gutsy version of the bug (#140921) I reported before I noticed this one. I'll copy the text here:

I believe that the wrong firmware has been included for the ivtv driver. I haven't actually installed Gutsy on
my MythTV box. However, experience with https://bugs.launchpad.net/ubuntu/+source/linux-source-2.6.20/+bug/131464 in Feisty will show this is true.

The file is ./ubuntu-firmware/ivtv/v4l-cx2341x-enc.fw with file size 262144 bytes.

On http://www.hauppauge.com/pages/support/support_pvr150.html there is a download button link which downloads http://hauppauge.lightpath.net/software/pvr150/cd_pvr150_27.zip

The file DriverA2/HcwFalcn.rom should be the file ./ubuntu-firmware/ivtv/v4l-cx2341x-enc.fw. I have attached that
file to this bug report.

I have checked the ivtv driver in the kernel source code to verify this is still the correct version of the firmware.

in drivers/media/video/ivtv/ivtv-firmware.c see

void ivtv_firmware_versions(struct ivtv *itv)
{
        u32 data[CX2341X_MBOX_MAX_DATA];

        /* Encoder */
        ivtv_vapi_result(itv, data, CX2341X_ENC_GET_VERSION, 0);
        IVTV_INFO("Encoder revision: 0x%08x\n", data[0]);

        if (data[0] != 0x02060039)
                IVTV_WARN("Recommended firmware version is 0x02060039.\n");

and

static int ivtv_firmware_copy(struct ivtv *itv)
{
 IVTV_DEBUG_INFO("Loading encoder image\n");
 if (load_fw_direct(CX2341X_FIRM_ENC_FILENAME,
     itv->enc_mem, itv, IVTV_FW_ENC_SIZE) != IVTV_FW_ENC_SIZE) {

where
#define IVTV_FW_ENC_SIZE (376836)

Which is the size of the version of firmware I recommend

Stuck in -proposed since December. Did it fix anyone's problems?

Fixed my problem. I was wondering why worked-fine-a-year-ago mythtv install started logging out whenever I tried to watch TV... Please do get this in so I don't have to overwrite the provided firmwares every time there's a kernel update. Thanks! :)

marking as invalid for > gutsy.

Gutsy continues to ship the wrong firmware -- the CX2341X firmware of file size 262144 is not compatable with the cx2341x drivers in the 2.6.22 kernel

This *is* a bug, and should *really* be fixed.

I upgraded the MythTV box to Gutsy at the end of the week and the problem was still there. So I manually copied the firmware. Has anybody checked Hardy for this?

There is a test package published in the gutsy-proposed archive, per
<https://wiki.ubuntu.com/StableReleaseUpdates>. Could you perhaps test that
this updated linux-ubuntu-modules package provides the correct firmware for
your system, without any need to copy it from elsewhere? That would help us
move forward with making this fix more broadly available.

> Has anybody checked Hardy for this?

Michale Krufky (the bug submitter) assures me that the hardy version of the
package ships the correct firmware.

Thanks, Steve. The proposed package appears to work. I shut the machine and unplugged the power cable for a while to be sure.
I also did a diff against the version I know works. It was the same.

Out of curiosity I looked in the log

Apr 30 is probably when I upgraded to Gutsy. It looks the kprintf statement in Gutsy might be whacko. The last boot is definitely with the proposed package.
If nobody else has a look, I'll look next week.
