[beagleboard] SGX driver and kernel 4.4
So, I've been away from the sgx stuff for awhile. I had it fully working on a Angstrom 3.x kernel quite a while ago. Now I'm on a beagle black with Debian and kernel 4.4.80. I'm a bit confused, as I working through the old Graphics_SDK_5_01_01_02 stuff, trying to get it compiled with all kinds of weird errors. Then I saw these drivers omap5-sgx-ddk-linux, which seem to be for the newer kernels? So I switched to this newer package and I was able to get this driver "pvrsrvkm" compiled and loaded with this message on my beagle: Sep 11 17:00:59 beaglebone kernel: [ 154.509813] [drm] Initialized pvr 1.14.3699939 20110701 on minor 1 Sep 11 17:00:59 beaglebone kernel: [ 154.626674] PVR_K: UM DDK-(3699939) and KM DDK-(3699939) match. [ OK ] So the driver is talking to the sgx hardware, good! But if I try any of the sgx demo stuff I get this: root@beaglebone:/usr/local/bin# ./sgx_init_test --- Start --- Try calling PVRSRVConnect with an invalid argument: PVR:(Error): PVRSRVConnect: Invalid connection.

Why is this? Is the omap5-sgx-ddk-linux the correct driver to be using for my 4.4.80 kernel?

[beagleboard] Re: Beagle black, SGX, OpenGL, and Graphics SDK with 3.8 kernel....no luck...
Well, I have the SGX stuff working with the 3.8 kernel. I do also have Qt 5.3.2 built and working. I have not had a chance to try the opengl platform on qt yet though. This 3.8 kernel is using the Angstrom-Cloud9-IDE-GNOME-eglibc-ipk-v2012.12-beaglebone-2013.09.05.img rootfs. I cross compiled on a 12.04 ubuntu host with the CodeSourcery toolchain. So, for the TI 4.10.00.01 graphics SDK to work with the 3.8 kernel, there are several patches that will be required. Some of these I got off the TI sitara forum, and the others I developed myself by backporting the 5.01.01.01 graphics sdk. I can tell you that without the patches, the 4.10 sdk will never work with 3.8! I am using the RobertCNelson 3.8 kernel at the moment, but I am pretty sure the official beagle repository 3.8 kernel will work also. There are changes to get the device node added, but there are also some timer related changes. I will try to release some patch files later, once I get things tidied up a bit. I am able to run all the 4.10 sdk ogles demos and they seem to run pretty smooth on the boneblack, and I am running them using a 7 LCD...looks pretty good! This is using soft floating point at the moment, so there is room for improvement. -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups BeagleBoard group.

[beagleboard] Beagle black, SGX, OpenGL, and Graphics SDK with 3.8 kernel....no luck...
So, for over a week I have been trying to get Qt 5.3.2 working with OpenGL on a BBB with a 3.8 kernel. So far, I haven't made much progress even though Ive spent many hours. I am stuck just trying to get OpenGL/SGX working on the black using the TI graphics SDK. I have tried 4 different 3.8 kernels, including the official ones as well as RobertCNelson's stuff. I have applied about 10 patches to the graphics SDK and the kernel. I can get the Graphics SDK built and installed, but I keep coming back to this: [5.263934] PVR: PVRCore_Init [5.270060] PVR: PVRSRVDriverProbe(pDevice=df0c2e00) [5.270176] PVR: SGX register base: 0x5600 [5.270189] PVR: SGX register size: 16777215 [5.270200] PVR: SGX IRQ: 37 [5.270233] PVR: EnableSystemClocks: Enabling System Clocks [5.270283] PVR_K:(Error): EnableSystemClocks: Couldn't get GPTIMER11 functional clock [512, opt/Graphics_SDK_4_10_00_ 01/GFX_Linux_KM/services4/system/ti335x/sysutils_linux.c] [5.270305] PVR_K:(Error): SysInitialise: Failed to Enable system clocks (171) [481, opt/Graphics_SDK_4_10_00_01/GFX_L inux_KM/services4/system/ti335x/sysconfig.c] [5.274037] PVR: PVRCore_Init: major device 240 When the pvrsvrkm driver tries to load, a clk_get() function fails in the driver and I cannot for the life of me figure out why? It's unclear exactly what timer this is, as the error indicates GPTIMER11, but inside the driver code it's referring to gpt7_fck. I assume this is timer7 in the Sitara? I have recompiled several versions of 3.8 kernels many, many times. Ive applied several patches. I have tried cutting out device tree objects and disabling many things to no avail. I have seen 3 or 4 folks who supposedly have gotten this TI pvrsrvkm and omaplfb driver to load and some of the test graphics apps to actually workI'd really like to know how they did it? The patches I have I collected from an FSE at TI, as well as some guy named Alexander. These apply to the Graphics SDk and the kernel, but nothing I have tried seems to get rid of this clock issue? I have built the graphics SDK with make BUILD=debug OMAPES=8.x PM_RUNTIME=1 all, and left out PM_RUNTIME, which seems to affect which portion of init code in the driver is executed...but I get another clock error, so no dice! Does anyone have a 3.8 kernel with OpenGL working? I tried installing the packaged drivers with Angstrom..but had no success there either. I know TI is only supporting the 3.12 kernel...but there are cape issues there, plus I have Xenomai running with 3.8 and I hate to jump to 3.12. Anyone have any success running OpenGL on 3.8 with a bone-black??? -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups BeagleBoard group.
