Hi,
I normally stick to LTS kernel releases and I just late-found 2
regressions while switching from 5.4 to the 5.10.
The whole thing is about Broadcom's Northstar platform and a bit quirky
iproc PCI driver (precisely: pcie-iproc-bcma part). The iproc PCI driver
supports both: platform device (based on DT) and bcma device.
Northstar support uses a mix of DT and bcma. The later is a bus with
EEPROM containing platform devices info. Its history is decades old and
that design comes from pre-DT times. In any case:
1. Northstar PCI controllers are bcma devices with minimalistic DT nodes
2. Everything worked great with 5.4 and quite OK with 5.8
Reference:
* arch/arm/boot/dts/bcm5301x.dtsi
* drivers/pci/controller/pcie-iproc-bcma.c
Could you look at those problems and check if it's possible to fix them
in some easy way (without a big refactoring) please?
**********
The first regression results in "no space for" and "failed to assign"
info-errors like:
[ 1.353173] pci 0000:00:00.0: BAR 8: no space for [mem size 0x00c00000]
[ 1.359816] pci 0000:00:00.0: BAR 8: failed to assign [mem size 0x00c00000]
They don't seem to cause any real harm, PCI devices are still visible.
It is caused by the:
commit 7ef1c871da16125ae58db13716fe82795dcbe3e8
Author: Rob Herring <robh@xxxxxxxxxx>

PCI: iproc: Use pci_parse_request_of_pci_ranges()
Convert the iProc host bridge to use the common
pci_parse_request_of_pci_ranges().
There's no need to assign the resources to a temporary list, so just use
bridge->windows directly.

The second regression results in "No bus range found for" errors like:
[ 1.096377] pcie_iproc_bcma bcma0:7: host bridge /axi@18000000/pcie@12000 ranges:
[ 1.103954] pcie_iproc_bcma bcma0:7: No bus range found for /axi@18000000/pcie@12000, using [bus 00-ff]
It results in not registering PCI bus at all.
Forwardtrace for that error:
iproc_pcie_bcma_probe()
devm_pci_alloc_host_bridge()
devm_of_pci_bridge_init()
pci_parse_request_of_pci_ranges()
devm_of_pci_get_host_bridge_resources()
of_pci_range_parser_init()
parser_init()
return -ENOENT;
It is caused by the :
commit 669cbc708122fc7a02282058a09f096200cee090
Author: Rob Herring <robh@xxxxxxxxxx>
Date: Tue Jul 21 20:25:13 2020 -0600
PCI: Move DT resource setup into devm_pci_alloc_host_bridge()
Now that pci_parse_request_of_pci_ranges() callers just setup
pci_host_bridge.windows and dma_ranges directly and don't need the bus
range returned, we can just initialize them when allocating the
pci_host_bridge struct.
With this, pci_parse_request_of_pci_ranges() becomes a static function.
