Hi

Thanks for your perfect work! I am interested in the Linux hot swap
project and now
doing some validation work about the compactPCI hot swap. So could you please tell me
whether there are some test suites for linux hot plug, if not, I'd like to write some test suites
for the project!

If you agree, could you please give me some requirements and
suggestion about the
test suites?

Thank you very much!

Best Regards
Guo Min

If you take a look at the archives for this list, you will see we just talked about this with another intel employee (who you also copied on the message) :)

In short, no there aren't any. Also, this is probably the wrong list for cPCI hotplug specific stuff.

Requirements:
- whatever makes you, and your employer happy.

In short, write up whatever you want and need, and if you could, post it to the list for others to use in the future if they want to do the same.

thanks,

To the extent that such tests cover things like verifying that streams of hotplug events are handled consistently, the latest CVS does have a simple facility to log events to files like /var/log/hotplug/pci.events (for CardBus, cPCI, hotplugPCI, etc) or /var/log/hotplug/events (for any event that doesn't have an agent enabled).

So you can collect hotplug events "live", and then (by writing simple software) play them back later ... Or just notice what kinds of hotplug events don't yet have /etc/hotplug/*.agent code.

I hope that facility will evolve -- and not primarily for testing support.

For example, I'd be interested in seeing some daemon thread monitoring /var/log/hotplug/input.events that's set up as a named fifo, as one way to solve hotplug's "need multiple security domains" issue. (That's an area where anyone who's familiar with those user mode APIs could contribute useful "seed" code in C, or likely even Perl ...)

But any test scripts you put together that are general purpose would likely help down the line. Both automated "do these events get handled correctly" scripts, and manual "plug in the adapter and verify that these N things got set up right".

for the other hot plug device and features, I will give out the test suites later.

Your testcase seems reasonable, but having the PCI device appear/disappear is IMO the trivial part of PCI hotplug. The vast majority of the problems I encountered while writing the cPCI drivers involved PCI resources. Most of my manual testing revolves around checking the contents of /proc/iomem and /proc/ioports before and after inserts and removes, as well as looking at the output of "lspci -vvv". With a fixed set of hardware, it may be possible to come up with testcases for resource allocation, but the general case is probably difficult to automate.

Something else to be aware of is that eventually I plan to support hardware that does not expose HS_CSR through the PCI extended capabilities. It looks like your testcase as it stands now will break if run in a setup that had such hardware.

PS: Are you working with Harold Yang? He's also at Intel but seems to be
having troubles using cPCI hotplug on his ZT5084 system.

[Guo,Min] Thank you for your kind suggestion, I will investigate and try to realize such
function.

[Guo Min]: I will take a look at the platform and revise my test cases, thank you very much!

[Guo Min]: Yes, I thought he had already solved the problems.

Hi,

I enhanced my test suites, added the following features

1. Check the io ports and io mem for cPCI devices,including two procedures, one is plug/remove ,the other is remove/plug. it needs to manual operation

2. check the io ports and io mem for PCI hotplug devices,including two procedures,
one is plug/remove ,the other is remove/plug.it can work automatically.

I had verified the ZT5550 cpci and Compaq hotplug PCI net devices with
the test cases.

Here is my initial test suite for cPCI (ZT5084 platform) and Compaq with e100 and e1000 hotplug network devices,
for the other hot plug device and features, I will give out the test

suites

Quoted 1 line

later.

Your testcase seems reasonable, but having the PCI device appear/disappear is IMO the trivial part of PCI hotplug. The vast majority of the problems I encountered while writing the cPCI drivers involved PCI resources. Most of my manual testing revolves around checking the contents of /proc/iomem and /proc/ioports before and after inserts and removes, as well as looking at the output of "lspci -vvv". With a fixed set of hardware, it may be possible to come up with testcases for resource allocation, but the general case is probably difficult to automate.

Something else to be aware of is that eventually I plan to support hardware that does not expose HS_CSR through the PCI extended capabilities. It looks like your testcase as it stands now will break if run in a setup that had such hardware.

Scott

PS: Are you working with Harold Yang? He's also at Intel but seems to be
having troubles using cPCI hotplug on his ZT5084 system.
