Re: [Announce] kernel-power stable v52 in Extras
 

@pali
May you consider to have another look at my (and now also akuma's) problem with kp and dsp libs (/etc/modprobe.d/bridgedriver)?
http://talk.maemo.org/showthread.php...postcount=1345

I took a look in kp53 modules postinst and saw that you remove there all mentioning of shm_size, but you do not remove the phys_mem_base (introduced with kp52). On purpose?
IIRC stock kernel did not start with that config (or better said without shm_mem=0x4000000).
What we would have with kp53 is shm_size removed and phys_mem_pool inside (for people upgrading from kp52 to 53).
Nothing to consider when only using kp, but when we need/want to u-boot stock kernel: reboot loop.

Re: [Announce] kernel-power stable v52 in Extras
 

Original fille /etc/modprobe.d/bridgedriver from package omap3430-dsp-baseimage-ti_0.201007-1+0m5_armel.deb has this content:

Default shm_size param in stock kernel is 0x400000 and defualt phys_mempool_base param is 0.

So removing any of those two params from /etc/modprobe.d/bridgedriver does not break or change any behaviour of stock kernel.

Re: [Announce] kernel-power stable v52 in Extras
 

Okay, would expect that too.
But see the config of akuma (and also also my experience). With this config the stock kernel produced a reboot loop.
Bringing back the 0x400000 let stock kernel boot.

-- edit
BUT as we are the only ones reporting I might fear that it is due to multiboot and its changed preinit? Could not see why (but that could be due to my limited knowledge :rolleyes:). If so I might understand you stop your support here!
Are there any other fellows out there willing to try to test above linked config with stock kernel?

And: it is not critical but just inconvenient (now that I know ;), so ...)

Re: [Announce] kernel-power stable v52 in Extras
 

@peterleinchen: when you will be able to boot stock kernel, please run uname -a. Also please post sha1sum of that problematic kernel driver /lib/modules/2.6.28-omap1/bridgedriver.ko

Re: [Announce] kernel-power stable v52 in Extras
 

@freemangordon: can you try to look at stock dridgedriver source code too? to confirm that default shm_size param is 0x400000?

Re: [Announce] kernel-power stable v52 in Extras
 

Will do so (but probably not today).

Ah now I see what you think: bridgedriver.ko got overwritten by installing dsp debs?

Okay, post later ...
TIA



Just remembered some info from akumo about installing cssu-thumb and jist doing the dsp lib thingy (http://talk.maemo.org/showpost.php?p...stcount=1342):
That would get multiboot out of the problem makers.

--temporary info:
~ $ sha1sum temp/kp52/modules/lib/modules/2.6.28.10-power52/bridgedriver.ko /lib/modules/2.6.28.10-power52/bridgedriver.ko

f82d6ba811e76ea19783b8ce07ab37d83d0099c9 /lib/modules/2.6.28.10-power52/bridgedriver.ko
I compared directly against unpacked kp52 modules deb and they are the same.

Re: [Announce] kernel-power stable v52 in Extras
 

This makes no sense, as 720p .debs install does not touch anything kernel related, it just replaces DSP codec nodes. IIRC

Re: [Announce] kernel-power stable v52 in Extras
 

Strange stranger ...

Now I booted stock kernel with following config:
options bridgedriver phys_mempool_base=0 base_img=/lib/dsp/baseimage.dof
and ... it booted. :confused:
(of course tryinmg to boot stock kernel with 0x500000 failed, was expected)

My kp52 with same config booted successful, too. So I will leave that as default.


Here is requested info:

if you still need.

I have no explanation why it now works on my device? And I am sure it did not 9 months ago, as I am not interested in stealing your time. :)
But why the hell akumo had the same problem then?

Re: [Announce] kernel-power stable v52 in Extras
 

My idea is that multiboot can use older version of kernel...

Re: [Announce] kernel-power stable v52 in Extras
 

Hmm, I do not get this.
Do you mean cannot handle?
No, multiboot is stone-age, and was created during early times. And did its work for lots of folks using plain stock and nitdroid kernel.
