Hello
Debugging a downstream port with slot capabilities indicating hotplug
capability is advertised in pci capability(id =0x10) .
None of the hotplug driver is getting invoked.
I assume pciehp_probe should've been called because its associated
with ".port_type = PCIE_ANY_PORT," in the pcie_port_service_driver
structure.
I assumed SHPC shpc_probe function would be called because the pci_id
table has PCI_CLASS_BRIDGE_PCI_NORMAL, but nothing related to hotplug
drivers is seen in the ftrace or dmesg.
Tried "pciehp.pciehp_force=1 pciehp.pciehp_debug=1" in the command
line but no luck
As part of port initialization if the hotplug capability is indicated
in the capability register the hotplug drivers should have been
invoked, but looks like its not the case.
Am I missing something?
Any information is appreciated.
Regards
Raghu

I would expect pciehp to work in this case, but there is some
negotiation between the OS and the firmware to figure out which
owns it.
I assume you have CONFIG_PCIEPORTBUS and CONFIG_HOTPLUG_PCI_PCIE
enabled? Can you supply the dmesg log and output of "sudo lspci -vv"?

Hi Bjorn,
I have a switch connecting to the Host bridge, one of the downstream
port(02:1.0) on the switch has the slot enabled.
Appended pcie_ports=native along with pciehp.pciehp_force=1
pciehp.pciehp_debug=1 to the cmdline and I see the driver creating symlink
to sysfs device node.
Does this mean pciehp can handle the hotplug events? asking this because
none of the functions in pciehp_core listed in ftrace?

Update:
Hi Bjorn,
Looks like the pciehp_probe is invoked and the corresponding ISR
(pciehp_isr) is triggered if there is an event, but somehow only
pciehp_isr is traced by ftrace but not the probe function.
Maybe my assumptions of ftrace need correction.
Thanks for the response.

From the dmesg log you attached:

I assume this kernel is running as a KVM guest. The firmware _OSC
says the platform (QEMU) doesn't support native PCIe hotplug, so
host->native_pcie_hotplug will be false. But of course
"pcie_ports=native" would set pcie_ports_native, so the portdrv
get_port_device_capability() will set PCIE_PORT_SERVICE_HP, which
allows pciehp to bind to 02:01.0.
The "pcieport 0000:02:01.0: pciehp: Slot #0" line shows that
pciehp_probe() was called.
I don't know whether QEMU supports PCIe hotplug interrupts though.
When do you expect pciehp to do something? Are you hotplugging a
physical device that is passed through to this guest?

Hi Bjorn,
Yes, it's a virtual x86 Qemu environment with rtl simulated pcie gen6
switch hooked to the host controller.
The simulation environment is 3rd party and my guess is it's a
passthrough(guessing) .
I can confirm that msi is received to the Qemu host because the USP
port has f0, f1, f2, f3, f4 and f4 is an scsi end point function and
interrupts are used for command/response.
I enabled a few more debugs, now I can see more information from
pciehp dumped into the kernel log.
Thanks for the details, I was not aware that _OSC flags need to be
built by firmware to enable native PCIe hotplug.

Hi Bjorn,
I was able to trigger an interrupt, the pciehp_isr was triggered and
there are "Timeouts" while processing the hotplug,
I suspect this is due to the slowness of the simulation platform, is
my assumption correct?

That usually means the slot does not generate software notification, but
for whatever reason decided not set the "No Command Completed Support"
in the slot capability structure.

Hello,
The platform I am working on is rtl simulation of pcie switch(Gen6)
with a backdoor mechanism to trigger the HotPlug event.
Tried following patches independently to have both hotplug and dpc
driver register and handle respective events.
https://patchwork.ozlabs.org/project/linux-pci/patch/20231223212235.34293-2-mattc@purestorage.com/
https://patchwork.kernel.org/project/linux-pci/patch/20240108194642.30460-1-mattc@purestorage.com/#25680870
Tried following
- Trigger hot removal and add, the event is triggered and respective
msi in /proc/interrupt increments and kernel logs the event(dmesg)
- Trigger hot removal and add, the event is triggered and respective
msi in /proc/interrupt increments and kernel logs the event(dmesg)
- Trigger DPC using "DPC software trigger" in DPC control register
The kernel hangs, the console is non-responsive.
Can dpc and pciehp co-exist and handle the events?

Yes, they're intended to coexist. Your platform firmware doesn't
advertise support for it, though:
[ 1.736168] acpi PNP0A08:00: _OSC: platform does not support [PCIeHotplug LTR DPC]
I don't think there's a kernel parameter to force DPC usage if the
platform doesn't advertise it. There should be a message like "DPC:
enabled with IRQ X" if the dpc driver is active.
Even if the dpc driver isn't active, I don't think the kernel should
hang if you trigger DPC. Since this is a QEMU guest, you should be
able to use a debugger to figure out why it's hung.

Hello,
The freeze was a platform issue, it's fixed and things are working as expected.
Using this patch from "Matthew W Carlis <mattc@purestorage.com>", will
this patch be merged in future ?
