Qiang, Mani
I have a RTS5261 mmc chip on PCIe3 on the Surface Laptop.
Is it based on x1e80100?
You would think so :P
Adding the global irq breaks sdcard detection (the chip still comes
up fine) somehow. Removing the irq makes it work again :|
I've confirmed that the irq number is correct
Yeah, I did see some issues with MSI on SM8250 (RB5) when global interrupts are
enabled and I'm working with the hw folks to understand what is going on. But
I didn't see the same issues on newer platforms (sa8775p etc...).
Can you please confirm if the issue is due to MSI not being received from the
device? Checking the /proc/interrutps is enough.
There's no msi-map for PCIe3. I recall +Johan talking about some sort of
a bug that prevents us from adding it?
Yeah, that's for using GIC-ITS to receive MSIs. But the default one is the
internal MSI controller in DWC.
Unless you just meant the msi0..=7 interrupts, then yeah, I only get one irq
event with "global" in place and it seems to never get more
Ok. Then most likely the same issue I saw on SM8250 as well. But I'm confused
why Qiang didn't see the issue. I specifically asked him to add the global
interrupt and test it with the endpoint to check if the issue arises or not.
Qiang, can you please confirm?
Sorry, I misunderstood what you mean. I only verified if link was up but
ignored the status of ep device
driver.
But look like this issue is because snpsys MSI irq is msked during probe.
Can you please also unmask BIT(23) - BIT(30) when unmask
PARF_INT_ALL_LINK_UP,
like this

}
After that, this issue is fixed on my setup.
Thanks,
Qiang
