Hi,
Between v5.15 and v5.16-rc the following (unrelated?) errors are
appearing in kernel.log:
resource sanity check: requesting [mem 0xff200000-0xff3fffff], which
spans more than 0000:00:0e.0 [mem 0xff298000-0xff29bfff]
caller devm_ioremap+0x45/0x80 mapping multiple BARs
pmd_set_huge: Cannot satisfy [mem 0x05e00000-0x06000000] with a
huge-page mapping due to MTRR override.
This is on Intel Edison (Merrifield), which has (from lspci):
00:0e.0 System peripheral: Intel Corporation Device 119b (rev 01)
Flags: fast devsel, IRQ 25
Memory at ff298000 (32-bit, non-prefetchable) [size=16K]
Memory at ff2a2000 (32-bit, non-prefetchable) [size=4K]
Capabilities: [b0] Power Management version 3
Capabilities: [b8] Vendor Specific Information: Len=08 <?>
Capabilities: [c0] PCI-X non-bridge device
Capabilities: [100] Vendor Specific Information: ID=0000 Rev=0
Len=024 <?>
Any suggestions on the cause of this would be welcome.
Ferry
