force unwind support off for the time being?)


Ok, so I have tested this and if we add the following to the omap 
defconfigs then this will enable frame pointers and disable unwinding 
support. Hence, this should avoid the problems seen with the 2007q3 code 
sourcery compiler.


# CONFIG_ARM_UNWIND is not set

Tony, would this be ok with you?

Russell, sorry I did not see this thread earlier.

 Is there any way of detecting the 2007q3 compiler?

 With normal GCC versions, you can use __GNUC__, __GNUC_MINOR__ and
 __GNUC_PATCHLEVEL__ to identify the three digit version number.

I don't know, most probably not. But Jon Hunter investigated the issue
and he found the issue was related to CONFIG_ARCH_WANT_FRAME_POINTERS:

http://www.mail-archive.com/linux-omap@vger.kernel.org/msg12403.html

So maybe we can fix or workaround this.

See the 'depends on' line in lib/Kconfig.debug.  The result is that
without the patch from Jon, even if you have CONFIG_FRAME_POINTERS=y
in your .config, it gets dropped if the arch doesn't set
CONFIG_ARCH_WANT_FRAME_POINTERS.

Tony, et.al.,

Any ideas when more LDP support will be pushed into mainline (such as
the framebuffer support)?
  

I'll be looking at the board-*.c patches for the next merge window
hopefully this week or next week.

Looks like LDP keyboard, touchscreen  RTC are pretty much ready
to go. Then the MMC has some regulator updates, but AFAIK the MMC
should work OK already.

For the framebuffer, Imre and Tomi know the status the best, so
I've added them to Cc.

Imre has been meaning to send a bunch of drivers/video/omap changes
to the fbdev list for a while now and LDP framebuffer may depend on
those. Imre, any news on the status of sending the fb patches
upstream?

Then there are the upcoming DSS patches from Tomi, but those still
need some work before they're ready to go.


Is there any news on this?  Will we see more functional OMAP3 / LDP
support queued for the next merge window?
  

Yes fro the stuff listed above, but still no news on the framebuffer
patches. Imre?



Added Stanley Miao to Cc. Here's an updated version of Stanley's patch to
add fb support for LDP.

I don't have an LDP, maybe you guys can give it a try against the mainline
kernel and see if it works! There might be some changes needed to 
drivers/video/omap/dispc.c too.. And those should be handled by Imre.


But if this works, at least we can then add support for few more boards
easily while waiting for Imre to send his updates.
  

Hi, Tony,

Now the kernel can't boot on LDP. The attached file is the boot log.

I will check it when I have  time.

Stanley.


Cheers,

Tony

 Sod it, I'm not going to bother with this crap with its stupidly long

 I've better things to be doing like washing the car.
 
 So you're on your own with LDP support for the next 9 days.  So this
 email marks the end of my pre-holiday Linux involvement.

Happy holidays :) We'll get the LDP patches ready by the time you're back.

Good to hear. What patches do you have applied?

None relating to DSS1, the rest are DSS2 patches (not enabled in  
defconfig), musb patches, etc.



What exactly is wrong with the touchscreen?


It seems to have a reduced resolution with lots of noise, tslib is  
unable to calibrate it to a usable state. It might be the mcspi  
problem the evm had (has?) all over again, haven't looked into that.



Got any patches for that?


none, sorry.

 Tony, et.al.,

 Any ideas when more LDP support will be pushed into mainline (such as
 the framebuffer support)?
   
 I'll be looking at the board-*.c patches for the next merge window
 hopefully this week or next week.

 Looks like LDP keyboard, touchscreen  RTC are pretty much ready
 to go. Then the MMC has some regulator updates, but AFAIK the MMC
 should work OK already.

 For the framebuffer, Imre and Tomi know the status the best, so
 I've added them to Cc.

 Imre has been meaning to send a bunch of drivers/video/omap changes
 to the fbdev list for a while now and LDP framebuffer may depend on
 those. Imre, any news on the status of sending the fb patches
 upstream?

 Then there are the upcoming DSS patches from Tomi, but those still
 need some work before they're ready to go.
 
 Is there any news on this?  Will we see more functional OMAP3 / LDP
 support queued for the next merge window?
   
 Yes fro the stuff listed above, but still no news on the framebuffer
 patches. Imre?
 

 Added Stanley Miao to Cc. Here's an updated version of Stanley's patch to
 add fb support for LDP.

 I don't have an LDP, maybe you guys can give it a try against the mainline
 kernel and see if it works! There might be some changes needed to  
 drivers/video/omap/dispc.c too.. And those should be handled by Imre.

 But if this works, at least we can then add support for few more boards
 easily while waiting for Imre to send his updates.
   
 Hi, Tony,

 Now the kernel can't boot on LDP. The attached file is the boot log.

 I will check it when I have  time.

Looks like the get_dss_clocks() in dispc.c at least needs updating for
omap3. It should use clkdev too now btw.

 Sorry, forgot to attach the boot log.

 Stanley.

Looks like you used the CodeSourcery 2007q3 toolchain. This had been
reported earlier. Switching to 2008q3 works.

OMAP_LDP: Support LCD display as a FB device on ZOOM MDK

Add glue to control the OMAP_LDP LCD as a frame buffer device
using the existing dispc.c driver under omapfb.

Patch updated for mainline kernel. Note that the
drivers/video/omap should be updated to pass omap_lcd_config
in platform_data. The patch should also be updated to compile
if twl4030 is not selected, and eventually to use the regulator
framework.
