Graphics SDK 4.05.00.03 X11 Support with Input

Nick Reed
Intellectual 465 points

We have been running the pre-packaged X11 binaries provided with the Graphics SDK to begin development of our applications under Enlightenment using E17's OpenGL accelerating Compositing support.  As mentioned in the release notes, this performs well provided the cursor is disabled in the Xorg.conf.  Disabling the cursor, however, causes the X server to crash anytime keyboard or mouse input is received while it looks for the cursor position.

One of the approaches we were evaluating to get input working with our Qt based application was to patch the X server source to avoid this crash.  To that end, we had a few questions:

  • Are there any patches necessary to the Xorg sources for operation in DRI mode with the PVR driver?
  • Is the source for the PVR X11 driver available either through TI or Imagination Tech.?  Or are binaries available for later versions of the X server?
  • Are there any other issues we may run into in trying to use our own Xorg build?
Thanks for any assistance you can offer.

    Hi Ralph,

    We have resolved all issues that Nick had reported by providing him with a release drop.

    You can download the same release with this ftp instructions

    Fullscreen 7080.Graphics_sdk_04_06_00_01_download_ftp_instructions.txt Download 
    The ftp pickup directory 'usithok' was created on 03/01/2012 05:30:00.
The files from the dropoff area have been moved to the pickup directory and are available for 7 days.

To retrieve the files from the pickup directory:

  1. Open an ftp session to ftppickup.ti.com.
         ftp ftppickup.ti.com

  2. Login with the userid 'pickup'.
         Name: pickup

  3. Enter the password.
         Password: piurh!

  4. Change directories to the pickup directory.
         ftp> cd /pub/share/usithok

     Note: If you are using a graphical ftp client, you will not 
           see the hidden pickup directory name usithok appear 
           in the file list.  You will need to use a manual 
           'Change Directory' or 'CD' command to change into the 
           dropoff directory.

  5. Set the file transfer mode to ascii or binary as necessary.
         ftp> bin

  6. Transfer the file.
         ftp> get <file>

  7. End the ftp session.
         ftp> quit

The files can also be retrieved with the url:

  ftp://pickup@ftppickup.ti.com/pub/share/usithok

List of files in the pickup directory 'usithok':
Graphics_SDK_setuplinux_4_06_00_01.bin
    (please download it now as it will expire by 8th March).

    Hi Prathap,

    Thanks for the link. Can I take it that this release will be the same as the publicly available graphics SDK version 4.06.00.01 when it comes out?

    Ralph,

    Yes almost close to that.  Some minor items below will also be resolved. Anyways they should not impact you & you can use this release till we make an official drop.

    1)Shader compilation issue with use of return statement in void functions & multiple returns in a function reported by Nick.

    2)Debug build metrics issue.

    3)Cleanup of install_dri.sh reported by you.

    Our plan is to make the official release by 1st week of April.

    Thanks,

    Prathap.
