There is a bunch of other GPIO control bits in there for other hardware blocks. Would explain the broken NAND flash behavior...Yes, my bad here. Sometimes is better to go to sleep :)).Do: u32 val = rt_sysc_r32(MT7621_GPIO_MODE); val |= PERST_MODE_GPIO; rt_sysc_w32(val, MT7621_GPIO_MODE);Much better result with that. Though ultimately it should clear bits 10 and 11 (both are PERST_MODE bits) and then OR in BIT(10).Ok, so the following should do the trick: rt_sysc_m32(PERST_MODE_MASK, PERST_MODE_GPIO, MT7621_GPIO_MODE); with PERST_MODE_MASK defined as: #define PERST_MODE_MASK GENMASK(11, 10) (patch attached with this changes)I have mostly good news and a little bad news :-) I should have tested more thoroughly last night. Anyway, the new patch works, even the IRQ of the PCI device. My Wifi PCI device works just as well now as it did with the 4.20 pci-mt7621.c/pci-mt7621-phy.c. I still get the lines: pcieport 0000:00:00.0: of_irq_parse_pci: failed with rc=-22 pcieport 0000:00:00.0: enabling device (0004 -> 0006) However that is referring to the root host PCI device (0000:00:00.0), not my PCI peripheral device (which is 0000:01:00.0). It is actually probed and working properly. That is the good news.That makes sense :). Good news are always good news even bads are coming also :))It would be also good to know what happen if you comment the following lines: pcie_write(pcie, 0xffffffff, RALINK_PCI_MEMBASE); pcie_write(pcie, RALINK_PCI_IO_MAP_BASE, RALINK_PCI_IOBASE); Are they really needed?Had no effect for me. Everything worked the same with or without those lines as far as I could tell.Ok, I won't include them when I send a clean patch series with all of this changes.[snip]Only one step more to get this properly working.Ok, now the bad news. I often get the boot hanging at various points in the PCI initialization, setup and probing. For example sometimes it hangs with boot up to: mt7621-pci-phy 1e149000.pcie-phy: Xtal is 40MHz Then sometimes it hangs at: mt7621-pci-phy 1e149000.pcie-phy: Xtal is 40MHz mt7621-pci 1e140000.pcie: Port 454043648 N_FTS = 0 mt7621-pci-phy 1e149000.pcie-phy: Xtal is 40MHz mt7621-pci 1e140000.pcie: Port 454043648 N_FTS = 1 mt7621-pci-phy 1e14a000.pcie-phy: Xtal is 40MHz mt7621-pci 1e140000.pcie: Port 454043648 N_FTS = 2 mt7621-pci 1e140000.pcie: pcie0 no card, disable it (RST & CLK) mt7621-pci 1e140000.pcie: pcie1 no card, disable it (RST & CLK) mt7621-pci 1e140000.pcie: pcie2 no card, disable it (RST & CLK)It is weird, here it is not initializing any port... All of them are disabled.And then I also see it hang up to: mt7621-pci-phy 1e149000.pcie-phy: Xtal is 40MHz mt7621-pci 1e140000.pcie: Port 454043648 N_FTS = 0 mt7621-pci-phy 1e149000.pcie-phy: Xtal is 40MHz mt7621-pci 1e140000.pcie: Port 454043648 N_FTS = 1 mt7621-pci-phy 1e14a000.pcie-phy: Xtal is 40MHz mt7621-pci 1e140000.pcie: Port 454043648 N_FTS = 2 mt7621-pci 1e140000.pcie: pcie1 no card, disable it (RST & CLK) mt7621-pci 1e140000.pcie: pcie2 no card, disable it (RST & CLK) mt7621-pci 1e140000.pcie: PCIE0 enabled mt7621-pci 1e140000.pcie: PCI coherence region base: 0x60000000, mask/settings: 0xf0000002 mt7621-pci 1e140000.pcie: PCI host bridge to bus 0000:00 pci_bus 0000:00: root bus resource [io 0xffffffff] pci_bus 0000:00: root bus resource [mem 0x60000000-0x6fffffff] pci_bus 0000:00: root bus resource [bus 00-ff] pci 0000:00:00.0: bridge configuration invalid ([bus 00-00]), reconfiguring It happens on cold or warm boots. Sometimes it boots up all the way and everything works perfectly.Can you try to change all the msleeps of the code driver in favour of mdelay's? Looks like some timing problem.Changed the msleeps to mdelays and it still hangs somtimes. I doubled the delay times in the msleeps and tried that too - that also sometimes hangs.If it doesn't work, it would be great to have a full trace of working 4.20 and no working current 5.x series version just to carefully compare them.I'll attach at the end a full working boot trace from 5.1 with the 4.20 pci-mt7621.c. I'll attach a 5.1 boot trace with your patch and hang below. Not that this very same image doesn't always hang. Same binary will sometimes boot fine.I had perfect reliable boot and operation with linux-5.1 using the older 4.20 pci-mt7621.c and pci-mt7621-phy.c.AFAICT, there is not pci-mt7621-phy.c in the v4.20, isn't it? Do you mean you put also that code into that version and compile them? Or are you just using "pci-mt7621.c"?I just leave that pci-mt7621-phy.c code in place in linux-5.1 when I copy in the linux-4.20 pci-mt7621.c - even though it isn't used in that case. One thing I always notice is that the PCI probing happens much earlier with the 4.20 pci-mt7621.c. Not sure that will have any impact though.It seems it is related because, looking at the trace which hangs I can see: mt7621-pci 1e140000.pcie: failed to get gpio perst mt7621-pci 1e140000.pcie: Parsing DT failed At that point gpio's driver are not being probed yet. This not happen with the original patch because it just access to memory to set up all the stuff intead of use the gpio's consumers apis which, IMHO, is the way to go. Can you try to return "-EPROBE_DEFER" if getting the gpio fails in initialization? (patch attached with this change and removing the two lines which seems to not be needed commented in previous patch)New patch tried. Behavior is no different. Occasional hang during boot. I can see that it does the probe, and now deferr. Full boot log of a hung boot below.Ok, so that means it was properly being deferred with the previous patch also. The original code set up all at a very early stage (arch_initcall) just after the pinctrl driver is being set up. The new one without my last patches was also being executed later because of the phy. At arch_initcall the 'phy_create()' is called before the phy module is initialized, so 'phy_class' is NULL, the new phy isn't placed in the right class, and it cannot be found. So the phy driver uses 'module_init' instead of 'arch_initcall' and it worked for the gnubee board. But according to your traces when it hangs the problem seems to be with gpio's being resetting or something so the pcie link is not in up state for any reason I cannot understand. So we have to determine if the problem is because of the phy and gpio init being done in later stages. We can try to change 'arch_initcall' to a later stage changing it to 'module_init' to see if it is a deferring problem or something. The other thing we can try to determine if it is a gpio access problem is to change in the last patch the gpio descriptor uses with you initial memory accessign hack to see if it eventually hungs or not. If this both tests result in eventually hung boot I'll try to prepare a patch with the current phy code in the 'arch_initcall' stage putting in the the same pci-mt7621.c file to see if order matters.

Now all of ports are being reset before enabling the phy. Also, power_off the phy is done before reseting the port so it should not hang now. The real problem here is if the pcie link is properly detected to get a working PCI. Patch attached.Tested with this patch. I still see the same occasional hang behavior. Sometimes boot up and scan work, sometimes it hangs. It is probably around 1 in 3 boots is good, 2 out of 3 hang (roughly speaking).No good numbers for us, yet :)I won't have much time today or tomorrow to dig deeper. But I will try and do some more proper debugging early next week.Just to be sure that the hang is because of powering off the phy on fail I directly unset clock bits for each port in the attached patch.
Applied this patch, and ran with it. I still get some boot time hangs. It does seem less often, for whatever that is worth. Sample trace hangs (just the last part of the kernel boot trace): Segment Routing with IPv6 sit: IPv6, IPv4 and MPLS over IPv4 tunneling driver NET: Registered protocol family 17 NET: Registered protocol family 15 8021q: 802.1Q VLAN Support v1.8 Loading compiled-in X.509 certificates mt7621-pci-phy 1e149000.pcie-phy: Xtal is 40MHz [HUNG] And another: Segment Routing with IPv6 sit: IPv6, IPv4 and MPLS over IPv4 tunneling driver NET: Registered protocol family 17 NET: Registered protocol family 15 8021q: 802.1Q VLAN Support v1.8 Loading compiled-in X.509 certificates mt7621-pci-phy 1e149000.pcie-phy: Xtal is 40MHz mt7621-pci 1e140000.pcie: Port 0 N_FTS = 1b102800 mt7621-pci-phy 1e149000.pcie-phy: Xtal is 40MHz mt7621-pci 1e140000.pcie: Port 1 N_FTS = 1b102800 mt7621-pci-phy 1e14a000.pcie-phy: Xtal is 40MHz mt7621-pci 1e140000.pcie: Port 2 N_FTS = 1b102800 mt7621-pci 1e140000.pcie: pcie1 no card, disable it (RST & CLK) mt7621-pci 1e140000.pcie: pcie2 no card, disable it (RST & CLK) [HUNG] And even another: Segment Routing with IPv6 sit: IPv6, IPv4 and MPLS over IPv4 tunneling driver NET: Registered protocol family 17 NET: Registered protocol family 15 8021q: 802.1Q VLAN Support v1.8 Loading compiled-in X.509 certificates mt7621-pci-phy 1e149000.pcie-phy: Xtal is 40MHz mt7621-pci 1e140000.pcie: Port 0 N_FTS = 1b102800 mt7621-pci-phy 1e149000.pcie-phy: Xtal is 40MHz mt7621-pci 1e140000.pcie: Port 1 N_FTS = 1b102800 mt7621-pci-phy 1e14a000.pcie-phy: Xtal is 40MHz mt7621-pci 1e140000.pcie: Port 2 N_FTS = 1b102800 mt7621-pci 1e140000.pcie: pcie1 no card, disable it (RST & CLK) mt7621-pci 1e140000.pcie: pcie2 no card, disable it (RST & CLK) mt7621-pci 1e140000.pcie: PCIE0 enabled mt7621-pci 1e140000.pcie: PCI coherence region base: 0x60000000, mask/settings: 0xf0000002 mt7621-pci 1e140000.pcie: PCI host bridge to bus 0000:00 pci_bus 0000:00: root bus resource [io 0xffffffff] pci_bus 0000:00: root bus resource [mem 0x60000000-0x6fffffff] pci_bus 0000:00: root bus resource [bus 00-ff] pci 0000:00:00.0: bridge configuration invalid ([bus 00-00]), reconfiguring pci 0000:00:00.0: PCI bridge to [bus 01-ff] pci 0000:00:00.0: BAR 0: no space for [mem size 0x80000000] pci 0000:00:00.0: BAR 0: failed to assign [mem size 0x80000000] pci 0000:00:00.0: BAR 8: assigned [mem 0x60000000-0x601fffff] pci 0000:00:00.0: BAR 9: assigned [mem 0x60200000-0x602fffff pref] pci 0000:00:00.0: BAR 1: assigned [mem 0x60300000-0x6030ffff] pci 0000:00:00.0: BAR 7: no space for [io size 0x1000] pci 0000:00:00.0: BAR 7: failed to assign [io size 0x1000] pci 0000:01:00.0: BAR 0: assigned [mem 0x60000000-0x601fffff 64bit]
Debugging would be very helpful.
I will try and get some time to really look deeper. Thanks for your efforts so far. Regards Greg _______________________________________________ devel mailing list devel@xxxxxxxxxxxxxxxxxxxxxx http://driverdev.linuxdriverproject.org/mailman/listinfo/driverdev-devel
