RE: [PATCH 1/1] ARM: DaVinci: video capture support... almost
Hi Kevin,
After applying your patch, the Kernel still crashed when
I ran the encode demo.
Fortunatly I've found a little hack which solves the problem.
It is the 2'nd change in the attached patch.
The 1'st change just eliminates an annoying compilation Warning.
Since I doubt that my hack can be considered as a proper fix,
I hope that you will find and fix the real bug.
Sincerely,
Alex

Subject: [PATCH 1/1] ARM: DaVinci: video capture support... almost
To: davinci-linux-open-source@linux.davincidsp.com
Message-ID: [EMAIL PROTECTED]
Straight forward port of the VPFE driver from the 2.6.10 kernel,
including some previous work done by Alex Rier. There are a few things
I need to cleanup before putting into the git tree:
1) video-buf layer support for contiguous buffers
2) potential reuse of tvp5150 instead of tvp5146
The implementation of (1) in this patch is not ready for the mainline
kernel, so I am currently working on it and will be submitting a patch
to the video4linux project soon.
For (2), if anyone is looking for a concrete way to contribute to the
open-source kernel, they could tackle it. I haven't looked at the
datasheets in detail, but at first glance, I think we could probably
use the existing tvp5150 driver for the tvp5146 instead of adding a
new driver as the current. The tvp5150 driver may need some minor
adjustments, but that is preferrable than having an entirely different
driver.

I'm not ready to integrate this VPFE into the git tree yet until I better understand the other kernel changes. Also, the generic changes to the video-buf layer are not quite right, and I need to work on something that's more acceptable upstream.

It would be useful for you to explain _why_ you want to change the timer period. There are almost certainly much better ways to achieve what you want than globally changing the timer period. You will take a significant performance hit in context switch overhead when reducing the timer period. You should strongly consider using the high-res timers instead. I’ve changed the actual value of HZ in include/asm-arm/param.h, but I don’t see any change: timer ticks are still 10ms. This can be shown by running procinfo –n1 on the DVEVM and examining IRQ35, which is the System Tick. Its value is increased with exactly 100 every second… As far as I can tell, the IRQ35 period is calculated in arch/arm/mach-davinci/time.c as: ((CLOCK_TICK_RATE / HZ) – 1), where CLOCK_TICK_RATE equals 27MHz (hardware timer). That's correct. Who can tell us what we need to do to increase the HZ as used in the kernel? This patch did it for me, although as I stated above, this is not recommended.

Do you have an idea why does it work with 2.6.10-mvl401 and fails with
2.6.19-rc3-omap1?
Thanks,

RE: Problem running 2.6.19-rc3-omap1 Kernel on TI DVEVM
Hi, I've applied the patch found at : http:/linux.omap.com/pipermail/davinci-linux-open-source/attachments/200 60626/08870398/machine-number-hack.bin http:/linux.omap.com/pipermail/davinci-linux-open-source/attachments/20 060626/08870398/machine-number-hack.bin But it didn't solve the problem. Where can I get 1.1.3_0.5,4 or later customized for DVEVM?

Hi, You are genious! arch/arm/config/davinci_evm_dm644x_defconfig allowed me to load and start the kernel. Many thanks!

Not realy. My kernel boots fine since I upgraded the bootloader. If I remember right you tool the kernel config from you old kernel ?? Have you tried to use the default config from arch/arm/config/davinci_evm_dm644x_defconfig ?
