[ECOS] PC VMware target broken

[ECOS] PC VMware target broken

[Iztok Zupet]

Hello,

 The PC VMware CVS target seems broken. RedBoot boots with a two minute
delay, before ethernet driver init is called and in an application a GDB
breakpoint never happens.

 As far as I remember, everything ran normally in March this spring.
I've looked at the CVS list, but found no records of any suspicious
change there.

 Does anybody remember what might have introduced VMware flaw?

In redboot

    * src/fs/ide.c: make sure IDE_STAT_BSY is 0 before checking other
    bits in the status register


It loops until timeout.
Might be this change. I know that I had the same delay when using the 
i386 target with redboot and ide and changed the qemu sources.
But now that it could be the same thing with vmware maybe it's an ecos bug?

Yes. It waits for 30 seconds for each IDE channel. But if You install a
disk in VMware virtual machine it complains about IDE reset command with
a "not implemented feature"...

But funny, it seems that IDE init is still called in RedBoot if one
disables the "Allow RedBoot to support disks" configuration option.
