These enhance %pR so we can print resource types and flags more easily.
This doesn't really add anything (other than a couple new messages
about host bridge apertures), but hopefully it will make things more
consistent and a bit easier to debug. Sample change (with "pci=use_crs"):
-pci 0000:00:03.0: reg 10 32bit mmio: [0xf6000000-0xf6ffffff]
-pci 0000:00:03.0: reg 14 io port: [0x2400-0x24ff]
-pci 0000:00:03.0: reg 18 32bit mmio: [0xf5ff0000-0xf5ff0fff]
-pci 0000:00:03.0: reg 30 32bit mmio pref: [0x000000-0x01ffff]
+pci_root PNP0A03:00: host bridge window [io 0x0000-0x0cff]
+pci_root PNP0A03:00: host bridge window [io 0x0000-0x2cfe]
+pci_root PNP0A03:00: host bridge window [io 0x03b0-0x03bb]
+pci_root PNP0A03:00: host bridge window [io 0x03c0-0x03df]
+pci_root PNP0A03:00: host bridge window [mem 0xf5d00000-0xf6ffffff]
+pci_root PNP0A03:00: host bridge window [mem 0x000a0000-0x000bffff]
+pci 0000:00:03.0: reg 10: [mem 0xf6000000-0xf6ffffff]
+pci 0000:00:03.0: reg 14: [io 0x2400-0x24ff]
+pci 0000:00:03.0: reg 18: [mem 0xf5ff0000-0xf5ff0fff]
+pci 0000:00:03.0: reg 30: [mem 0x00000000-0x0001ffff pref]
Changes from initial post to v2:
- tidied vsprintf stack buffer to shrink and compute size more accurately
(Joe Perches)
- use %pR for decoding, %pr for "raw" (with type and flags) instead of
adding %pRt and %pRf
- split cleanup from printk changes for easier review
I plan some future patches to add more messages and change some dev_dbg()
to dev_info(), so this series is strictly to change the resource formatting.
