Porting the SGX Graphic to the ipnc

Dear all,

When i porting the graphic engine to the IPNC Project(TI8148) it occurs and error and i don't know how to solve it.

Does anyone can help me to fix the problem?

the setting in our board as below:

Because of the IPNC memory setting(512MB),and our memoey size is (1GMB). I Change the memory size form the uboot.

#define CONFIG_NR_DRAM_BANKS		2		/* we have 2 banks of DRAM */
#define PHYS_DRAM_1			0x80000000	/* DRAM Bank #1 */
#define PHYS_DRAM_1_SIZE		0x20000000	/*modify 256 MB-->512MB 20120305*/
#define PHYS_DRAM_2			0xB0000000	/* DRAM Bank #2 */
#define PHYS_DRAM_2_SIZE		0x20000000	/*modify 256 MB-->512MB 20120305*/

and My bootargs.

bootargs=mem=80M@0x80000000 mem=256M@0x90000000 vram=50M ti814xfb.vram=0:48M,1:1M,2:1M notifyk.vpssm3_sva=0xBFD00000 console=ttyO0,1

I also modify the the filesys/opt/ipnc/autorun.sh

cd /opt/ipnc

insmod sbull.ko
umount /mnt/ramdisk 2>/dev/null
rmmod sbull.ko 2>/dev/null
insmod sbull.ko
sleep 1
mkdosfs -v /dev/sbulla 2>/dev/null
mkdir /mnt/ramdisk 2>/dev/null
mount -t vfat /dev/sbulla /mnt/ramdisk 2>/dev/null
insmod g_file_storage.ko file=/dev/sbulla stall=0 removable=1

amixer sset 'PGA' 80
sleep 2

cd /opt/ipnc
./init.sh
sleep 2
#./system_server& //Disable the setting below.
#sleep 28
#./boot_proc 1&
#sleep 2
#./boa -c /etc &
#sleep 4
#./wis-streamer &
#Sleep 2
#./boot_proc 2&
#sleep 2

the i follow the wiki to build the SGX driver and example.

http://processors.wiki.ti.com/index.php/Graphics_SDK_Quick_installation_and_user_guide

make BUILD=release OMAPES=6.x SUPPORT_XORG=0 all

make BUILD=release OMAPES=6.x SUPPORT_XORG=1 install

then i power on the target board then set-->

>> make BUILD=release OMAPES=6.x SUPPORT_XORG=0 all

>> make BUILD=release OMAPES=6.x SUPPORT_XORG=1 install

the arguments are not matching between make and make install

But in any case, the error mentioned happens because SGX_REVISION is not obtained – can you run below line and post what happens (after running /etc/init,d/38xx-demo) ?

/etc/init.d/devmem2 0x56000014

I copy the command line from wiki and forget to change the setting.
My setting==>SUPPORT_XORG=0
make BUILD=release OMAPES=6.x SUPPORT_XORG=0 all 
make BUILD=release OMAPES=6.x SUPPORT_XORG=0 install

And I am not follow all of the wiki to porting the Graphic engine, Because Some setting in the IPNC is different from the Ezsdk
Like:
a.
wiki-->./slaveloader
ipnc-->./bin/fw_load.out
b.
wiki-->insmod vpss.ko sbufaddr=0xA0200000
ipnc-->insmod ./kermod/vpss.ko mode=hdmi:1080p-60 sbufaddr=0xbfb00000
and others,

When I execute the command line: /etc/init.d/devmem2 0x56000014
I got the information.
root@dm814x-evm:/opt/ipnc# /etc/init.d/devmem2 0x56000014
/dev/mem opened.Unhandled fault: external abort on non-linefetch (0x1018) at 0x40379014

And I execute the command again:
root@dm814x-evm:/opt/ipnc# /etc/init.d/devmem2 0x56000014
/dev/mem opened.Unhandled fault: external abort on non-linefetch (0x1018) at 0x4049b014

The Memory mapped address is always not the same.

Gidday there,

I am seeing the same bus error with a custom 8148 board. Did you find a solution to getting the SGX responding to memory accesses correctly?

Thanks in advance

Joshua

p.s. I ran the linux_prcm_ipcam application, after rebuilding it to remove the 'SGX_Disable()' operation and the SGX clock seems to be disabled. I ran the sgxperf_check script mentioned earlier and got the following output:

Since my previous post I have established that the SGXPLL_CLKCTRL register is not writable from Linux. I am able to set this register from u-boot and it retains the value once booted. This allowed me to be able to enable the CLKOUT for the SGX PLL, but the status still reports the PLL as in bypass (not locked) mode. I am able to modify the CM_SGX and PM_SGX registers from Linux (with devmem2) but never the SGXPLL_CLKCTRL. When I load the pvrsrvkm module, the kernel reports that it is unable to enable the SGX clock, because it never enters the 'locked' state (always in bypass).

Very odd.

In my project I am providing primarily Linux support, and eventually the hardware manufacturer discovered that uboot was explicitly disabling the SGX component. Once that was fixed, the SGX became functional.

One note, though, is that because the IPNC uses different stuff in the VPSS, this only works with FBDEV=no. This way only pvrsrvkm.ko and omaplfb.ko are required. No vpss.ko, nor ti81hdmi.ko are required. For rendering you need to use egl calls and render to a pixmap. Lookaround for the gleslayer code from TI for examples of how to configure it.
