-Add some known CHIPID entries.
-Add a code for BCM5906 into bge_chipinit(). We have to do more work for
BCM5906.
-Fix the case of setting a flag in BGE_PCI_DMA_RW_CTL (on conventional PCI).
attach pcmcia devices before interrupts are enabled. This is unclean
because pcmcia drivers use tsleep(9) in the attach code path but it
worked all the time and it is too late to change this on the 5.0 branch.
So just tolerate it.
Fixes a regression on hpcsh reported by Valeriy E. Ushakov.
per device info taken from FreeBSD driver. Tested by snj@ on 8111C.
Should closes PR kern/40955.
Note on old 8169 chips IP hw csum must be enabled to use TCP/UDP hw csums,
but I'm not sure if these newer chips still have the same restriction.
so check for a non-NULL configuration descriptor before dereferencing.
Should fix a crash reported by Nicolas Joly per PR kern/41048.
(It still doesn't look good that the ioctl which unconfigures the device
returns EIO -- either it is legitimate or it isn't -- but since this
is a pullup candidate I don't dare to change user visible behaviour.)
z8530sc.c:
Check pending interrupts in a loop until all requests are handled.
The old comments said it would cause horrible latency to sun3x floppy etc,
but serial ports should have higher priority than disks anyway.
z8530tty.c:
Don't enable and disable TX interrupts on each transmit start and completion
because it could cause possible race conditions.
Instead, set ZSWR0_RESET_TXINT on each TIE interrupt to clear the request
as other kbd drivers attached at zs(4).
Tested on cobalt, macppc, news68k, sparc, and sun3.
device will remain in a wait-for-more-stuff-to-be-written state delaying other
SCSI calls, esp. some read-size or read-layout calls, until its told there is
no more comming.
To fix this, on last close explicitly flush the caches releasing the device
from this mode and allowing other SCSI commands to reach it.
This fixes PR 40528

- To get 16 bit one's complement value from uint32_t variable,
higher 16 bits should be ignored.
- RFC 1624 describes methods to recalculate checksum field in headers,
i.e. one's complement of one's complement sum that could be 0x0000,
but we don't have to use the strategy to deduct one's complement sum
itself which won't be zero but should be 0xffff.
Found on debugging mec(4) on sgimips O2.
There are still about 1600 left, but they have ',' or /* ... */
in the actual variable definitions - which my awk script doesn't handle.
There are also many that need () -> (void).
(The script does handle misordered arguments.)
- bus_dmamap fixes, with checks against NULL
- move the rings' allocation code later in iwi_attach() to avoid NULL pointer
dereference if allocation fails
- avoid double free() in case of failure during attach. If an allocation fails,
do not free the ring directly, as it is handled by iwi_detach()
- only set ring->count for RX/TX rings when ring allocation is successful, or
else the for loop during detach will fail with a NULL dereference.
- call pci_intr_disestablish() if iwi_reset() fails during attach; driver is
in an incoherent state, interrupt handler should not be used.
Proposed by me on tech-net@, approved by christos@. Compiled and tested
with GENERIC and XEN3_DOM0 kernels.
in IP headers, so we have to deduct not only IP option headers but all
IP headers. But in TCP/UDP layer we can assume the IP header is valid
and a sum of the IP header part should be 0xffff, so we don't have to
bother to deduct it from the computed checksum.
which don't have EXT_RFA and IPCB support. From hme(4) driver and
FreeBSD's fxp(4). Tested on i82559.
XXX: Probably we should have a common function to parse RX packet headers
XXX: to handle a raw checksum value and share it among hme(4) and gem(4) etc.
already powered down. This change prevents PCI bus exceptions
(indicated by NMI) when, for example, I detach the whole device
tree on a Soekris net4521:
com1: detached
NMI ... going to debugger
Stopped in pid 0.1 (system) at netbsd:sipcom_stop+0x4d: pushl $0
db{0}> continue

(On the AMD Elan SC520, the NMI occurs at the instruction after
the write or, if the write was posted, at either that instruction
or some later one.)
enabled:
- don't enable interrupts before calling uhci_run()
- check if the controller's interrupt is enabled in uhci_intr()
The issue is that uhci_run() may tsleep(), uhci_intr1() may be called before
uhci_run() is complete and disable it because it found it halted.
Now a uhci controller can be successfully exported to a NetBSD Xen domU :)
not 82550, so don't set FXPF_EXT_RFA (available only on 82550/82551)

Tested on Intel PRO/100 VM with 82562EM/EX PHY by ISHII Kimio
on current-users, and should also fix PR kern/40431.
because EXT_RFA for RX cksum is always available with IPCB for TX cksum
but i82558 and i82559 have only EXT_TXCB without IPCB.
Tested on the following fxp cards:

when bus_dmamap_create fails, then the map pointer is undefined.
age_dma_free() assumes, the map pointer is NULL. Make the assumption
always true by setting the map pointer to NULL in bus_dmamap_create()
error path in order to prevent age_dma_free() to call bus_dmamap_destroy()
on an invalid map.
to 2 for now. strategy routine must be written, for now only parsing and
support routines are available. This is work in progress code and should be
taken very carefully.
interrupt map, interrupt handler and dma maps.
Also prevent call to bus_dmamap_destroy() when bus_dmamap_create() failed.
The nfe_free_* routines assume, the map pointers are NULL but they
are actually undefined. Make the assumption true by making them NULL
in the error path of bus_dmamap_create().
All together, this fixes crashes when nfe_attach() fails.
ok martin@
disk queue is being held. Work around this by dropping the lock before
bdev_strategy(), and re-grabbing the lock afterwards. This is a
temporary measure until I get to gutting this queue locking code.
There has been some success with this in addressing PR#39993.
This patch is from Antti Kantee. Thanks!
via ECDT, we would print:
acpiec0 at acpi0 (EC, PHP0C09-0): ACPI Embedded Controller (disabled)
The embedded controller isn't actually disabled, but instead this driver
instance, so change the message to read:

Not directly related to the PR but this bug was discovered while testing.
