Hiya,
Several observations in 2.3.16 not present in 2.2.12 (I use gcc 2.95.1
for both kernel versions):
!!! PLEASE CC ANY REPLIES !!!
# cat /proc/version
Linux version 2.3.16 (root@emma1) (gcc version 2.95.1 19990816
(release)) #4 Fri Sep 3 23:25:35 CEST 1999
# uname -a
Linux emma1 2.3.16 #4 Fri Sep 3 23:25:35 CEST 1999 i586 unknown
(UniPenguin AMD K6-2/300 stepping 0, 128 MB RAM, VIA Apollo MVP3)
1) during booting up, 2.3.16 does not succeed in probing serial
interrupts, 2.2.12 does.
Here 2.3.16 bootup log (manually wrapped):
Serial driver version 4.30 with MANY_PORTS MULTIPORT SHARE_IRQ
DETECT_IRQ SERIAL
ttyS00 at 0x03f8 (irq = 0) is a 16550A
ttyS01 at 0x02f8 (irq = 0) is a 16550A
ttyS02 at 0x03e8 (irq = 0) is a 16550A
ttyS03 at 0x02e8 (irq = 0) is a 16550A
2.2.12 is able to deduce the actual irqs.
2) 2.3.16 say oops once setserial tries to "autoconfigure" a UART,
2.2.12 does not. By further trying I found that the ooops is autoconfig
related, with uart 16550a, setserial is fine.
Results with varing parameters:
# setserial /dev/ttyS0 irq 4 autoconfig
OOPS HERE
# setserial /dev/ttyS1 irq 3 uart 16550A
NO OOPS
# setserial /dev/ttyS2 port 0x3e8 irq 4 uart 16550A
NO OOPS
# setserial /dev/ttyS3 port 0x2e8 irq 3 autoconfig
OOPS HERE
There is 2nd attached ooops that is generated by:
# setserial /dev/ttyS0 auto_irq skip_test autoconfig
# setserial /dev/ttyS1 auto_irq skip_test autoconfig
# setserial /dev/ttyS2 auto_irq skip_test autoconfig
# setserial /dev/ttyS3 auto_irq skip_test autoconfig
3) 2.3.16 makes setserial report strange, offset errors on my fourport
compatible VSCom 400/750 PRO (ISA, 4 * TI16750, IRQ sharing, 922 kBit/s
payload per port, IRQ vector register). These parameters are fine with
2.2.12:
# setserial /dev/ttyS4 baud_base 921600 uart 16750 irq 10 port 0x180 ^fourport
# setserial /dev/ttyS5 baud_base 921600 uart 16750 irq 10 port 0x188 ^fourport
# setserial /dev/ttyS6 baud_base 921600 uart 16750 irq 10 port 0x190 ^fourport
# setserial /dev/ttyS7 baud_base 921600 uart 16750 irq 10 port 0x198 ^fourport
# setserial /dev/ttyS4 set_multiport port1 0x1c2 mask1 0xf match1 0xf
but give the following errors with 2.3.16:
Trying to free nonexistent resource <01a0-01a7>
Trying to free nonexistent resource <01a8-01af>
Trying to free nonexistent resource <01b0-01b7>
Trying to free nonexistent resource <01b8-01bf>
Not sure where this comes from. These don't oops.
