I have two questions<br>
I haven't actually installed the latest snapshot because I remember reading
that it was broken. If I was to install it, how do I apply the patches you
have given me.<br>
<br>
<br>
the init_ide function: what is it actually doing? Is it sending a reset or
something to the IDE? What is it supposed to do?<br>
<br>

<pre wrap="">Hello Angelo,<br><br>I have once written a small README for our ide driver, and I <br>looked for it (and the ide driver itself)in the current RTEMS <br>CVS, but it seems it is either gone or has never been <br>included. Therefore I send you the corresponding archive with <br>the IDE driver and the README. In the README, there are some <br>lines of code from our test application, showing how to <br>integrate our IDE driver.<br><br>At a second glance, one step is missing in the README: the <br>driver table.

<pre wrap="">You must create these two variables in your "init" module to <br>specify the number of ramdisks to be created and the <br>size/characteristics of these disks.

<pre wrap="">It doesn't - the implementation is hardcoded for powerpc. But you can<br>port it to pc386 with minimum changes, I think. But unfortunately current<br>IDE driver implementation have architecture which is hard to extend.<br>We propose the following architecture:<br><br>generic ATA driver (chip and CPU independant; only implementation of ATA<br>standart) locates in c/src/exec/libblock (although I'm not absolute sure<br>about this - may be another directory may be more appropriate)<br><br>generic IDE controllers driver and particular drivers for standart ide<br>controller chips locate in c/src/libchip/ide<br><br>if ide capacity is integrated into CPU then drivers for such ide locate in <br>c/src/lib/libcpu/myCPU<br><br>and if ide controller is somthing custom (for example on FPGA) then<br>driver for it goes to c/src/lib/libbsp/myBSP<br><br>Such architecture allows, for example, simply start IDE for any target<br>board - just implement particular o
n-board IDE controller driver and go<br>on.<br><br>Currently I've done most part of the work. Because of this I don't think<br>that port of Linux driver is necessary now (but of course, than more<br>activities then better :)). Also license difference also need attention.<br><br><br>Regards,<br> Eugeny<br><br></pre>

<pre wrap="">Currently I'm working on the another implementation of ATA<br>driver which is a bit more chip(I mean IDE<br>controllers)/CPU independant than thye implementation<br>provided<br>by Thomas Doerfler. Currently it will be PIO mode<br>implementation but both poll and interrupt driven. Also<br>architecture of the driver will allow easy extention for<br>any IDE controller and for DMA mode. I've already have successful mount of<br>msdos partition on real IDE hard disk and successful read of a file.<br>I hope I will able to provide something stable (more or<br>less) by the end of the next week.<br><br></pre>

<pre wrap="">At least the last (broken) snapshot had Thomas' driver in it.<br><br>I think the source for everything libblock, libfs, and IDE driver<br>was up to date in there minus unsubmitted code like Eugeny is<br>mentioning.<br><br></pre>
