Are there some reports of the ti-gfx stuff working on such recent kernels? Have you looked at the Yocto meta-ti layer at http://git.yoctoproject.org/cgit/cgit.cgi/meta-ti/ ? If I look there, they apparently don't have anything more recent than 3.0 or 3.1. Also, are you still trying on the Beagle-XM, or have you switched to the BeagleBone Black? > > You must use a soft-float toolchain (ie Code Sourcery) as the binaries > provided by the Graphics SDK are soft-float.

But that call has been introduced in 3.3 only, so for 3.2, you would still need to call clk_prepare(). Or maybe you can do something like: #if LINUX_VERSION_CODE < KERNEL_VERSION(3,2,0) int clk_prepare_enable(struct clk *clk) { return clk_enable(clk); } #elif LINUX_VERSION_CODE < KERNEL_VERSION(3,3,0) int clk_prepare_enable(struct clk *clk) { res = clk_prepare(clk); if (ret < 0) return res; res = clk_enable(clk); if (res < 0) { clk_unprepare(clk); return res; } return 0; } #endif this way, you can simply the rest of the patch by just doing s/clk_enable/clk_prepare_enable/.

In this particular case, I notice that Thomas repeats a lot of review comments that I've made a week ago, so writing "review comments from Arnout not taken into account" would have helped :-) Or maybe you missed those?

The SDK did support OMAP4 in 4_04_00_02. OMAP1/2 devices are too outdated to consider in the package. Focus of this package is on the frame buffer based devices. Omapdrm/dmabuf and additional changes will be merged eventually. regards, Prabu -----Original Message----- From: buildroot-bounces@busybox.net [mailto:buildroot-bounces@busybox.net] On Behalf Of Nicolas Dechesne Sent: Wednesday, June 26, 2013 4:22 AM To: Arnout Vandecappelle Cc: buildroot@busybox.net Subject: Re: [Buildroot] [RFC v2 1/1] ti-gfx: add new package On Tue, Jun 25, 2013 at 11:42 PM, Arnout Vandecappelle <arnout@mind.be> wrote: > On 25/06/13 18:29, Spenser Gilliland wrote: >> >> This is WIP of adding the TI Graphics SDK to Buildroot > > > It's not really _the_ graphics SDK, since it only supports a subset > of TI platforms (no OMAP1, OMAP2 or Davinci, and I'm not sure about OMAP5 either). well, historically, in the Pandaboard days (OMAP4/OMAP5), a different graphics SDK was being used.

Hi, My company is working on a AM3517 board. We are using Technexion's TAM3517 board for development right now. I was working on TI's SDK a few weeks ago but some more urgent things came up. I would definitely like to help if we can get it working in Buildroot. I can also help in testing. I don't know much about the history about TI's GFX SDK. I don't know about the soft float issue either. I was trying to run it with mfpu=neon parameter in the toolchain. There are some other things I'm not certain. I was working with 4_09_00_01 version and I think it works on AM35xx right? Also I thought TI only supported kernels up to 2.6.37 for AM3517. I can't remember where I get that idea, but I know Technexion doesn't provide any later kernels for their AM3517 boards. I don't know how buildroot works exactly but I started reading the documentation. I hope I can help. We are hoping to use EGL and Qt5. Sorry if I wrote technically incorrect stuff, I worked on SGX SDK for a short while last month and I realize I have forgotten most of what I did now : )

Yes, the RobertCNelson kernel has builds up to 3.9.6. I am using this with fairly good success. I've been using the meta-ti layer extensively to understand the process of installing the SGX drivers. Many things refer to a 3.8 kernel from ti. However, this kernel was unbootable on the Beagle-XM. This may be a more apporiate option for the Beagle Black though. > Also, are you still trying on the Beagle-XM, or have you switched to > the BeagleBone Black. The Beagle-XM is the current target. From the start, I was trying to read the revision number on the SGX core using devmem2. However for some unknown reason, devmem2 is not working properly on the Beagle-XM. When I finally tried the devmem from busybox, the revision was correctly read. Thus, I'm thinking that there is a bug in devmem2 which is causing the problem.

It's a sensible thing to do as many packages require egl or gles libraries. It's easier to just add an PKG_CHECK_MODULES to configure.ac then to add a bunch of different ifdefs for each and every opengl implementation.

Sorry about that, they were good comments but I was just trying to get it functional and most of the comments were cosmetic in nature. I'll get them all fixed up soon. Spenser

Dear Arnout Vandecappelle, On Tue, 25 Jun 2013 23:42:58 +0200, Arnout Vandecappelle wrote: > In this particular case, I notice that Thomas repeats a lot of review > comments that I've made a week ago, so writing "review comments from > Arnout not taken into account" would have helped :-) Or maybe you missed > those? I've explicitly asked Spenser to send some RFC versions of his patches regularly, since other people are interested in OpenGL support for OMAP3/AM335x, and it also everyone to keep track of the status of Spenser's work. It is quite understandable that Spenser focuses first on getting the thing to work before cleaning up everything, so we should be tolerant with regard to the quality of those RFC patches and the fact that Spenser does not necessarily take into account all review comments immediately. Best regards, Thomas

This is WIP of adding the TI Graphics SDK to Buildroot Current Status: Kernel Drivers load without errror. pvrsrvctl starts with no errors. Some demos run, others do not. gstreamer videotestsrc ! eglglessink does not work. TODO: Install startup files for sgx core. Create .pc files to simplify additional packaging. Hard Float Binaries Testing, lots of testing. Additional Info: I've been using the 3.9.6-x3 tag of the kernel at https://github.com/RobertCNelson/stable-kernel by use of the LINUX_OVERRIDE_SRCDIR option. You must use a soft-float toolchain (ie Code Sourcery) as the binaries provided by the Graphics SDK are soft-float. (hard float is on the TODO list) To load the driver manually use the following: modprobe omaplfb modprobe bufferclass-ti pvrsrvctl --start --no-module Signed-off-by: Spenser Gilliland <spenser@gillilanding.com> --- package/Config.in | 1 + package/opengl/libegl/libegl.mk | 4 + package/opengl/libgles/libgles.mk | 4 + package/opengl/libopenvg/libopenvg.mk | 4 + package/ti-gfx/Config.in | 54 +++++++++++ package/ti-gfx/ti-gfx-km_install_modules.patch | 14 +++ package/ti-gfx/ti-gfx-newclkapi.patch | 62 +++++++++++++ package/ti-gfx/ti-gfx.mk | 116 ++++++++++++++++++++++++ 8 files changed, 259 insertions(+) create mode 100644 package/ti-gfx/Config.in create mode 100644 package/ti-gfx/ti-gfx-km_install_modules.patch create mode 100644 package/ti-gfx/ti-gfx-newclkapi.patch create mode 100644 package/ti-gfx/ti-gfx.mk
