Hello all,
I have been facing an issue with PCIe device rescan, pci subsystem
could not be able to allocate resource.
I think the issue is PCIe resource resize.
pci 0000:0a:00.0: reg 10: [mem 0x00000000-0x00003fff 64bit pref]
pci 0000:0a:00.0: reg 18: [mem 0x00000000-0x03ffffff 64bit pref]
pcieport 0000:02:08.0: BAR 9: can't assign mem pref (size 0x6000000)
pci 0000:0a:00.0: BAR 2: can't assign mem pref (size 0x4000000)
pci 0000:0a:00.0: BAR 0: can't assign mem pref (size 0x4000)
Linux kernel : 2.6.34.10 (It is very old. Have no option so can't use
latest version)
Arch : mips
I also applied the following patch series to 2.6.34.10 kernel but the
result is same resource resize fails.
http://lkml.indiana.edu/hypermail/linux/kernel/1102.1/02823.html -
PCI: refactor io size calculation
https://groups.google.com/forum/#!topic/linux.kernel/LuQ4xbwwWU4 -
PCI: honor child buses add_size in hot plug configuration series
https://lkml.org/lkml/2011/6/20/422 - PCI: fix cardbus and sriov
regressions series
https://lkml.org/lkml/2012/1/21/35 - PCI : bridge resource
reallocation patchset series
and resource: ability to resize an allocated resource patch.
Steps I followed
===============
1. Put the PCIe device in reset mode from uboot
2. Boot kernel (lspci will not show the device)
3. Bring PCIe device out of reset mode
4. To rescan PCI bus do echo 1 > /sys/bus/pci/rescan - (rescan is
must, kernel's hotplug isn't working).
After rescan I can see device in lspci and also resource allocation
failure message in dmesg o/p.
In the normal scenario i.e device not in reset mode while booting
kernel, then the address range allocated is
11c00c0000000-11c00efffffff : PCI Bus 0000:02 whereas in failure
scenario i.e device in reset mode, the range
is 11c00c0000000-11c00dfffffff : PCI Bus 0000:02.
Attached PCI dmesg output
dmesg.working.txt - device not in reset mode while booting kernel
dmesg.rescan.txt - device in reset mode while booting kernel
The attached files also have output of /proc/iomem in both scenarios.
Thanks In advance.
