PSP Introduction and Product FAQ

What is PSP ?

• PSP stands for Platform Support Products and is created with the intent to provide OS ports,device drivers and sample applications to kick start development on a TI SOC platform by customers.

Why PSP ?

• PSP reduces the development effort for TI's customers by providing them the base port and drivers. This enables TI's customers to focus on the application development reducing overall time to market.

On what platforms are Linux PSP supported and the mapping between LSP versions and supported platforms ?

• For the Linux PSP offerings on the DaVinci family of devices & OMAPL137 TI has collaborated with Monta Vista and offers a product called LSP (Linux Support Package). The LSP are based on the Monta Vista Professional edition (Pro) product from Monta Vista. The MVL Pr0 versions are based of MV Linux kernel. The table below gives a mapping of the LSP Product releases, the platforms supported and corresponding MVL Pro versions and MVL Pro kernel versions.

	DM644x	DM355	DM6467	DM357	DM365	OMAPL137	MV Version	MV Kernel Version

LSP2.20	No	No	No	No	No	Yes	MV Pr05.0	MV 2.6.18 Kernel

What is the mapping between the Linux PSP Releases and the DVSDK releases and various patch level?

• The LSP is released as part of the DVSDK (Digital Video Software Development Kit). The table below gives a mapping of the DVSDK release versions and the corresponding LSP release versions.

LSP Version Number	DVSDK Version Number	Current patch level on TI extranet or part of LSP
LSP1.10	DVSDK 1.20	Patch level 50
LSP1.20	DVSDK 1.30 (GA release done)	Patch level 14. Up to LSP 1.10 patch level 37 is already part of LSP 1.20.
LSP1.30	DVSDK 1.40 (GA release available)	Patch level 13. Up to LSP 1.10 patch level 37 and patch level 46 is already part of LSP 1.30.
LSP2.00	DVSDK 2.00 (Release would be available in 1Q 09)	Please read through release notes. At a top-level we have tried to keep the LSP 2.00 at feature parity with LSP 1.x
LSP2.10	DVSDK 2.10 (Release would be available in 1Q 09)	Please read through release notes. At a top-level we have tried to keep the LSP 2.00 at feature parity with LSP 1.x
LSP2.20	OMAP L137 SDK 2.00

What is the mapping between TI released patches and MV kernel patches?

• Based on discussions with MV we have a table below which gives a map between TI patch number (and name) and the corresponding number (name) in MV patch stream. The patches 38-45 submitted by TI has not been accepted by MV and would not be part of the MV patch stream.
  
• All the MV patches corresponding to a TI patch number have to be applied in sequence (serially). For eg:// the MV patch number corresponding to TI patch level 31 is 1013. This means that a LSP 1.10 customer (who would be at MV patch level 785) would have to apply all patches from patch 786 to 1013.

Where can I find latest PSP patches?

Latest PSP patches are available in the Update Advisor under Platform Support Package in the Davinci MontaVista Linux based Platform package section.

The latest patch version on LSP 1.10 is PatchLevel 50

This Patch level50 release adds the support for the following new features :-

- Adds the USB Interrupt Endpoint Scheduling feature
- Stores proper DMA information for Status End points.
- Supports MMC/SD write protection.
- Supports PG 2.1 silicon version of DM644x by reverting the field inversion workarounds done to 
support previous PG revisions. For PG 1.x, the workarounds will remain in place even if the 
patch is applied.
- TCM and DTCM are being enabled from u-boot.

The latest patch version on LSP 1.20 is PatchLevel 14 This release adds the support for the following new features :-

- Adds the USB Interrupt Endpoint Scheduling feature
- Supports MMC/SD write protection.

 to support previous PG revisions. For PG 1.x, the workarounds will remain in place even if 
 the patch is applied.
- This patch release adds the SDIO stack support. The SDIO stack support is a port of the SDIO 
stack available in the “Linux SDIO Stack project” hosted in Source Forge. TI has done a port 
of this stack to the DM644x platform. The core stack themselves are not modified and released 
as downloaded from the SourceForge site. This patch include the SDHC support and performance 
improvements in the core SDIO stack for MMC/SD. The SDIO feature is provided for reference only.

The latest patch version on LSP 1.30 is PatchLevel 13 This release adds the support for the following new features :-

- Support for NAND boot mode
- Support for Checking bad blocks in UBL
- U-Boot has been changed to store the ENV variables at block offset 0, instead of block offset 4.
- NAND partition information has been modified in the kernel. 
- Adds the USB Interrupt Endpoint Scheduling feature & USB OTG Support

What is LPTB (Linux Performance Test Bench) ?

• Linux Performance Test Bench (LPTB) is a custom tool targeted at evaluating the performance of Linux device drivers for TI-Davinci and OMAP35x platforms. The LPTB supports device driver throughput measurements in conjunction with CPU load. The tool employs custom methodologies for throughput measurement (except for ethernet where iperf is used). The CPU load is measured using the proc filesystem (/proc/stat) entries. The package supports user level applications for Video, Audio, Networking, Storage, Serial driver measurements and kernel level modules for EDMA and VLYNQ throughput measurements, To download the latest Linux Performance Test Bench release, please click here. Refer to the Release Notes, Reference Guide and the User Guide for specific details.

The simple, scalable and configurable architecture enables the user to easily add different platform support to the existing product and to configure the LPTB to a specific product, platform and driver combination. The command line interface gives the user the flexibility to automate the execution of performance tests through shell scripts.

For what platforms are the BIOS PSP supported and what is the mapping between the BIOS PSP Releases and the DVSDK releases ?
