khwl.o

khwl.o (khwl.o) is a driver for working with the MG35 hardware.

Version: N/A

Status: N/A

khwl.o

Description

khwl.o contains functions for accessing eeprom, i2c bus, EM85xx, video memory, overlay, etc. The driver seems to be accesed via /dev/realmagichwl0.

Originally written in C (in COM style), it has many indirect method calls, and is therefore somewhat difficult to decode.
Fortunately, a large part of the KHWL module (25%) is microcode. Another 5% is unused for (eg) hardware detection, multiple board support, etc. And 20% for strings, mostly referring to included headers.
Currently handles basic hardware reset, microcode loading, dram/i2c/pio driver.
Parts left to build: tv encoder driver, mpeg decoder driver, board driver, eeprom driver, properties.
C coders welcome. Must speak Assembly.

There are some references to the following chips, which seem to be present in the Kiss player: Sii168 (DVI transmitter), Sm2288, Saa7114 and Fs400. Not sure if they are present in MG35.

Inside there is also a list of products (??). The same list is present in the corresponding KiSS module, that's why we presume they are both based on the Sigma Designs SDK.

There are also references to EM84xx, which means this based on an even older SDK. Note: there are some source files floating in the internet for the EM84xx SDK, maybe they prove useful.

A GPLed version of this module for the KiSS player is here.
