Re: [Haifux] Lecture about PCI?
Hi,
A good idea for a very interesting subject ! I'm also interested, and
I also do think
that two lectures on this are better than one, if it is possible from your side.

Re: [Haifux] Lecture about PCI?
OK, thanks, I got the hint. :) As for the taking a double slot: I know the tradition of going into the small details, so yes, including how to write a driver down to the code level would indeed take two slots at least. This was not my intention, since I've learned that all these details are forgotten until the information becomes really useful (and the kernel's API may very well change until then...). It's the principles that one remembers, and that the source code says little about. The thing is that without any prior knowledge, it's very difficult to even read the code of a driver, because it's not clear what the driver needs to accomplish, and why it's doing it the way it does. My thought was to fill that gap. And also give some background about how this magic works. I mean, I could take it down to the packet level between a PCIe card and the CPU, (and several other down-to-earth issues), but unless you're a hardware designer, you have nothing to do with that knowledge.

Hi,
Great idea, I would love to attend.

Re: [Haifux] Lecture about PCI?
"me too".
are you sure a single lecture will suffice for these two topics (i.e.
both hardware coverage, and PCI drivers coverage)? also, since the
drivers coverage will probably assume basic knowledge of writing
drivers, while the hardware thing can be interesting to
non-kernel-programmers as well - it may be logical to split this in two.

Re: [Haifux] Lecture about PCI?
Oh, that's a good idea! I'm interested.
It will be great to make some order in my head redrawing that PCI
thing. I'll be glad to hear about both PCI and PCIe. And your lecture
agenda sounds just right.

[Haifux] Lecture about PCI?
Hi all,
These days I'm working on making a PCI Express interface in hardware
(FPGA) and writing a Linux driver for it. When I'll be done with that, I
suppose I'll know a thing or two about the PCI bus.
Now, not that it's something to happen in the near future, but I just
wondered: What's the level of interest in a lecture about PCI (or more
like PCI Express?). I'm talking about the hardware (and protocol)
principles of a PCI vs PCIe buses (which are completely different), a
bird's view on the configuration of a PCI device ("plug and play", done
by BIOS for most of us), then a bit about bus mastering and DMA, and
wrap it all up with describing the anatomy of a Linux PCI driver. Just
so one knows what it's trying to accomplish when reading the source. Ah,
and we also have IRQ's and MSI's. A lot of fun, in short.
This is a pretty heavy lecture to prepare, but if I'll see you guys here
getting crazy about the idea, I'll consider it. :)
Eli
