SGX drivers for OMAP3530 for Linux-omap-2.6.33

Can you confirm you are using the toplevel Makefile (in the root folder of the Graphics SDK), to build the modules  ?

Yes iam using top level makefile

make OMAPES=3.x all

it will build pvrsrvkm module only...

to build omaplfb.ko

cd OMAP35x_Graphics_SDK_3_01_00_06/GFX_LINUX_KM/eurasion/build/linux/omap3630_linux/kbuild

make BUILD=debug all

it build omaplfb.ko in GFX_LINUX_KM/services4/3rdparty/dc_omap3430_linux/kbuild/omaplfb.ko

Regards,

Ashok

This method will not work.

Can you find out why the toplevel makefile does not build omaplfb as expected ? Also please read the Getting Started Guide online, for the proper options for building the SDK.

Hi

Now with Top make file the omaplfb & pvrsrvkn modules are build .

But iam getting below errors when i insert the omaplfb modules.

Can you please try this on 2.6.32 ? We have also tried this on 2.6.34, but not on 2.6.35. It would be good to confirm a working version first before we look at causes.

My kernel source is  linux-omap-2.6  (someone get it through git, and give it to me, so I don't know whether it get from)

I Modify Rules.make under  /home/terry/Desktop/beagle/SDK_BIN/OMAP35x_Graphics_SDK_setuplinux_3_01_00_07

I'm sure I pointer to the right place, but when I make OMAPES=3.x all, it shows error as follow

It seems that it cannot find the right include path, so I modify Makefile.KM

 make -C $(GFX_KERNMOD_SRCPATH) KERNELDIR=$(KERNEL_INSTALL_DIR) TI_PLATFORM=omap3430 BUILD=debug EXTRA_CFLAGS=-I/home/terry/Desktop/beagle/kernel/Sourcery_G++_Lite/arm-none-linux-gnueabi/libc/usr/include EXTRA_CFLAGS+=-I/home/terry/Desktop/beagle/SDK_BIN/OMAP35x_Graphics_SDK_setuplinux_3_01_00_07/GFX_Linux_KM/include4 EXTRA_CFLAGS+=/home/terry/Desktop/beagle/SDK_BIN/OMAP35x_Graphics_SDK_setuplinux_3_01_00_07/GFX_Linux_KM/services4/include

It still get an error

Is there anything I do wrong?

Hi

Do the below modifications in source problem will be solved , no need to  make changes in  Makefile.KM

1) /home/terry/Desktop/beagle/SDK_BIN/OMAP35x_Graphics_SDK_setuplinux_3_01_00_07/GFX_Linux_KM/services4/3rdparty/bufferclass_ti/bc_cat.c

replace

.ioctl = bc_ioctl

to

.unlocked_ioctl = bc_ioctl

2) comment width_align

 //width_align = cpu_is_omap3530() && omap_rev_lt_3_0() ? 32 : 8; and replace with
 width_align = 8; ( depends on OMAP  for OMAP3530 it is 8)

3) in bc_cat.c   & bufferclass_example.h

 include<linux/slab.h>

Thanks very much! It almost works, original errors totally disappear, but the compiler complain that:

/home/terry/Desktop/beagle/SDK_BIN/OMAP35x_Graphics_SDK_setuplinux_3_01_00_07/GFX_Linux_KM/services4/system/omap3430/sysutils_linux.c:36: fatal error: plat/resource.h: No such file or directory

Does it mean I miss resource.h in my kernel source?

I found resouce.h in other kernel source, so I think it's due to this missing file in my kernel source

resource.h will be in  asm/resource.h in linux-2.6.33 replace in place of plat/resource.h

linux-omap-2.6 git is in: http://git.kernel.org/?p=linux/kernel/git/tmlind/linux-omap.git;a=summary

some errors comes from kernel version  changes

 ioctl  relplace with unblock_ioctl 

omap_rev_lt_3_0:   width_align = cpu_is_omap3530() && (omap_rev() < OMAP3430_REV_ES3_0) ? 32 : 8;
