Hi all,
my resource-manageres for pci hardware still have following problem.
I can start them multible times for the same pci-device.
I would expect an error-code of pci_find_device(…PCI_INIT_ALL…) for
the second instance of the recource-mnanager.
I do not use the PCI_SHARE-Flag!
How can my resource-manager exclusive grab the pci-device, so that a
second start of my manager cannot attach to the pci-resources of the
same device?
-Michael
pci_find_device() does not check the PCI_SHARE flag. Only
pci_attach_device() checks the PCI_SHARE flag and returns an error code if
the attach fails.

Sorry, was a typo.
I use pci_attach_device() and the second instance of the
resource-manager does not get an error for the
pci_attach_device(…PCI_INIT_ALL…)
I tested this on qnx 6.3 SP1 ppc.

Can you please give me the pci_attach_device() lines that you are using in
your code? I have tried a pci_attach_device(…PCI_INIT_ALL), followed by a
second one, and the second one fails with a resource busy error code. What
return code are you checking?

Yes, I will send you a small sample on monday.

Return code of pci_attach_device.(NULL => error, else ok)
Did you try to start your process 2 times, or did you just call
pci_attach_device(…PCI_INIT_ALL…) twice in the same context?

Attached you will find the source-tree of a sample programm.
Syntax: pciattach -v vendor -p device [-i index]
After calling pci_attach_device(…PCI_INIT_ALL) the program waits 30
seconds, so that you can start a second/third/… instance of the
program and no instance of the process generates an error?!?
Where is the problem in my source?
-Michael
I have corrected your source code and attached the updated source to this
posting. Calling pci_attach_device() with no init flags is a special case
for the pci utility, so that is why it is succeeding.

Hugh,
thank you very much.
Now, I have a way to correct my drivers.
I use the the two-step way, because pci_attach_device cannot search for
Vendor/Device and Subvendor/Subsystem.
So I search for Vend/Dev without Resource-Allocation, check
subvendor/subsystem and if they match I allocate the recources with the
2nd call of pci_attach_device.
My workaround is now, to call pci_detach_device after the 1st call and
than call pci_attach_device a second time with resource-allocation.
If the behavior of the pci-bios-manager is correct for the 2 step way,
you should change the documentation for pci_attach_device and clarify
the difference between the 1st sample-source(1 step) and 2nd
sample-source(2 step):
e.g. Use 1st sample for your drivers.
Use 2nd sample for your pci-info tool.
Just a thought:
Wouldn’t it be nice to have a flag which includes Subvendor- and
Subsystem-ID in the search?

I have corrected your source code and attached the updated source to this
posting. Calling pci_attach_device() with no init flags is a special case
for the pci utility, so that is why it is succeeding.“Michael Tasche” <> michael.tasche@esd-electronics.com> > wrote in message

Can you please give me the pci_attach_device() lines that you are using

your code?
Attached you will find the source-tree of a sample programm.
Syntax: pciattach -v vendor -p device [-i index]
After calling pci_attach_device(…PCI_INIT_ALL) the program waits 30
seconds, so that you can start a second/third/… instance of the
program and no instance of the process generates an error?!?Where is the problem in my source?
