Hi,
on an Intel system, I'd like to assign a PCI Device (dual port serial
controller, 8250 compatible chipset) to a non-root cell. Please find
more details of the card in lspci-root.txt. This is the card as it is
seen by the root-cell, before being assigned to the non-root cell.
As exemplarily shown for an E1000e card in linux-x86-demo.c, I followed
those steps to assign the card:
- Add memory regions
- Add the pci device
- Add its caps
- Add access bits to I/O ports
... to the non-root cell configuration.
In the non-root cell, probing of the card fails with:
[...]
[ 1.551079] serial 0000:01:00.0: enabling device (0400 -> 0403)
[ 1.559060] querying PCI -> IRQ mapping bus:1, slot:0, pin:0.
[ 1.574310] serial 0000:01:00.0: can't find IRQ for PCI INT A;
probably buggy MP table
[ 1.582375] serial 0000:01:00.0: Couldn't register serial port 20c0,
irq 0, type 0, error -28
[...]
(see dmesg.non-root.txt)
AFAICT, while this card support MSI interrupts, the driver wants to use
legacy interrupts, but can't find the IRQ. In the non-root world, lspci
reports this would be 0, which is clearly not correct.
In the root cell, the card has IRQ 16:
[ 1.921700] IOAPIC 0:
[...]
[ 1.921811] pin10, enabled , level, low , V(10), IRR(0), S(0),
remapped, I(000F), Z(0)
The non-root cell knows this irqchip. Any suggestions what I'm missing?
I guess the kernel would like to access MADT tables, but we don't have
those tables of course. So how can the kernel detect which IRQ is being
used? Who or what carries this information (in case of legacy IRQs)?
Not related, but this issue raised another question: On x86, we supress
probing of non-existent platform serial devices in non-root cells with
8250.nr_uarts=n. Why do we have to do this? My local machine doesn't
have a single serial device, and the kernel doesn't even try to probe.
So why does non-root Linux?
Is it again due to missing ACPI tables that carry such platform information?
Last but not least: The dual-port serial card has one interrupt, two I/O
regions and some MMIO regions (that I don't need). To assign the card, I
could also 'just' map the I/O ports and the interrupt to the non-root cell.
Just out of curiosity: In this manner, would it be possible to share an
interrupt between two cells? If so, it should be even possible to
partition the card.
Thanks
Ralf
