Re: [coreboot] Out of heap space

[pyro]

Greetings,

It should fall back, but not everything does that properly. Just for
checking the basic functioning, any old USB 1.1 device (keyboard, mouse,
hub) will do to at least see that it was recognized and configured.

IIRC, the sequence is:
1. detect that a device is connected to the port
2. enable the port
3. Assign a USB ID with a setup packet
4. query for device type and strings
5. If a suitable block device, load the payload.

5 used to be a stream object (like in the old LinuxBIOS code) handed to
a copy of the the ELF loader. the read method set up the request and
called into the USB polling loop. I'm guessing that's

One potential issue there is that control of the physical port between
UHCI or OHCI (for 1.1) and EHCI (for 2.0) is determined by a bit in a
register. I'm not sure what happens if it's set wrong, but I suspect it
could look like your debug output.

was this exact setup working before r54? One possability is that the USB
code always had a bug that wasn't visible when allocations were quietly
double the requested size.

G'day,
sjames
