Subject: [PATCH] arm: cns3xxx: fix writing to wrong PCI registers after
|
||||
alignment
|
||||
|
||||
Originally, cns3xxx used it's own functions for mapping, reading and writing registers.
|
||||
|
||||
Commit 802b7c06adc7 ("ARM: cns3xxx: Convert PCI to use generic config accessors")
|
||||
removed the internal PCI config write function in favor of the generic one:
|
||||
|
||||
cns3xxx_pci_write_config() --> pci_generic_config_write()
|
||||
|
||||
cns3xxx_pci_write_config() expected aligned addresses, being produced by cns3xxx_pci_map_bus()
|
||||
while the generic one pci_generic_config_write() actually expects the real address
|
||||
as both the function and hardware are capable of byte-aligned writes.
|
||||
|
||||
This currently leads to pci_generic_config_write() writing
|
||||
to the wrong registers on some ocasions.
|
||||
|
||||
First issue seen due to this:
|
||||
|
||||
- driver ath9k gets loaded
|
||||
- The driver wants to write value 0xA8 to register PCI_LATENCY_TIMER, located at 0x0D
|
||||
- cns3xxx_pci_map_bus() aligns the address to 0x0C
|
||||
- pci_generic_config_write() effectively writes 0xA8 into register 0x0C (CACHE_LINE_SIZE)
|
||||
|
||||
This seems to cause some slight instability when certain PCI devices are used.
|
||||
|
||||
Another issue example caused by this this is the PCI bus numbering,
|
||||
where the primary bus is higher than the secondary, which is impossible.
|
||||
|
||||
Before:
|
||||
|
||||
00:00.0 PCI bridge: Cavium, Inc. Device 3400 (rev 01) (prog-if 00 [Normal decode])
|
||||
Flags: bus master, fast devsel, latency 0, IRQ 255
|
||||
Bus: primary=02, secondary=01, subordinate=ff, sec-latency=0
|
||||
|
||||
After fix:
|
||||
|
||||
00:00.0 PCI bridge: Cavium, Inc. Device 3400 (rev 01) (prog-if 00 [Normal decode])
|
||||
Flags: bus master, fast devsel, latency 0, IRQ 255
|
||||
Bus: primary=00, secondary=01, subordinate=02, sec-latency=0
|
||||
|
||||
And very likely some more ..
|
||||
|
||||
Fix all by omitting the alignment being done in the mapping function.

||||
