OMAP4 PowerVR driver

Tim Verstraete

Hi,

we are evaluating the OMAP4 processor and when I try to build the Linux system through Yocto I see that the PowerVR is not included for this device. So I went to the TI website and found the latest driver: http://software-dl.ti.com/dsps/dsps_public_sw/sdo_sb/targetcontent/gfxsdk/latest/index_FDS.html

And what I saw in the release notes is that the OMAP4 is not included: http://processors.wiki.ti.com/index.php/RN_4_06_00_02 So i was not wondering, is this because the support for this processor is seized OR what should I see behind this.

thank you in advance for your reply,

kind regards,

Tim

Hi Tim,

You can use the GLP releases for OMAP chipset. Please check the http://omappedia.org/wiki/Ubuntu_Pre-Built_Binaries to find more information on Ubuntu Releases for OMAP with support for SGX.

Thanks & Best Regards,

Venkat

Fist of all, thanks for replying ... i did not know ubuntu core and i will check it out.

this helps me for evaluating the device for performance BUT it does not explain why in the latest TI driver releases the OMAP4 is not included. Why is this?

kind regards,

Tim

Hi Tim,

As per my understanding, the SGX drivers deliverables for OMAP chipsets is different from that of other chipsets due to changes in architecture and customizations required for OMAP chipset.

Therefore, I think OMAP is not listed for SGX driver on those RN series of releases as they would not have been tested.

Thanks & Best Regards,

Hi Tim,

The link you have sent clearly mentions the following. "This release includes the Linux graphics drivers for the SGX530 family of chipsets:...". OMAP4 does not fall under this category as it uses SGX540. Also as Venkat mentioned, SGX packages are combined along with full linux/android distributions released by TI.

Hope this answers your question.

Dear Satheesh and Venkat,

first of all, thanks for replying ... OK, so the general PowerVR driver for SGX540 is not the same as for OMAP4 PowerVR SGX540 because of tweaks in the core?

I did find a RN release with the SGX540 in it: http://processors.wiki.ti.com/index.php/RN_4_04_00_02 and therefore I found it strange that the newer driver releases do not have this support anymore ...

When you say full linux distributions, you mean the ubuntu releases probably?

Thanks in advance,

Kindr egards,

Tim

Hi Tim,

Yes, the full linux distributions mean the ubuntu releases which can be accessed from the following link.

https://launchpad.net/~tiomap-dev/+archive/release.

I thinks the use cases and software API support for OMAP4 PowerVR SGX540 would be quite different when compared to that on RN releases. I am not sure if there are any differences in the SGX 540 core chipset.

Thanks & Best Regards,

Venkat
