gutteridge | bwfm.c: KNF a comment (spaces->tabs)
|
| 1.35 |
| 01-Aug-2023 |
mrg | fix simple mis-matched function prototype and definitions.
most of these are like, eg
void foo(int[2]);
with either of these
void foo(int*) { ... }
void foo(int[]) { ... }
in some cases (such as stat or utimes* calls found in our header files),
we now match standard definition from opengroup.

like other interfaces.
Remove cargo-culted check for manual roaming.
|

riastradh | if_attach and if_initialize cannot fail, don't test return value
These were originally made failable back in 2017 when if_initialize
allocated a softint in every interface for link state changes, so
that it could fail gracefully instead of panicking:
https://mail-index.NetBSD.org/source-changes/2017/10/23/msg089053.html
However, this spawned many seldom- or never-tested error branches,
which are risky to have around. And that softint in every interface
has since been replaced by a single global workqueue, because link
state changes require thread context but not low latency or high
throughput:
https://mail-index.NetBSD.org/source-changes/2020/02/06/msg113759.html
So there is no longer any reason for if_initialize to fail. (The
subroutine if_stats_init can't fail because percpu_alloc can't fail
either.)
There is a snag: the softint_establish in if_percpuq_create could
fail, potentially leading to bad consequences later on trying to use
the softint. This change doesn't introduce any new bugs because of
the snag -- if_percpuq_attach was already broken. However, the snag
can be better addressed without spawning error branches, either by
using a single softint or making softints less scarce.
(Separate commit will change the signatures of if_attach and
if_initialize to return void, scheduled to ride whatever is the next
convenient kernel bump.)
Patch and testing on amd64 and evbmips64-eb by maya@; commit message
soliloquy, and compile-testing on evbppc/i386/earmv7hf, by me.

jdolecek | discussed with thorpej@, and it seems it's better to allocate the bss
alignment buffer statically (as part of softc) just to be sure to not
affect performance
|
| 1.24 |
| 30-May-2020 |
jdolecek | reduce stack usage in bwfm_rx_event_cb(), can use KM_SLEEP because
this is called from workqueue handler (i.e. thread context)

jdolecek | constify, and make static where possible
|
| 1.22 |
| 25-Mar-2020 |
thorpej | Add a file type entry for CLM files.
|
| 1.21 |
| 25-Mar-2020 |
thorpej | - Refactor the firmware loading code into a set of common routines in the
core driver that understand how to find model-specific files before the
generic files. This greatly simplifies the firmware loading procedure
in each of the bus front ends. Adding additional firmware file types
(such as CLM files) much simpler.
- Make firmware image selection table-driven rather than a set of switch()
and if() statements.
- Add several additional firmware image entries.

Implement the BPF direction filter (BIOC[GS]DIRECTION). It provides backward

Don't pass empty mbufs to the network stack.
Avoid changing signedness bit with << in sdmmc_ioreg.h
Reported by <prlw1>
If the controller doesn't support switch func (opcode 6) then skip
setting this but continue with other settings. This allows us to use
a card, albeit at a lower speed.
Fix races in sdmmc tasks and teach ld@sdmmc to abort xfers on detach.
- Teach sdmmc_add_task to queue it only if not already queued.
- Remove now-redundant logic to avoid repeated queueing elsewhere.
- Teach sdmmc_del_task to wait until task has completed.
- Call sdmmc_del_task in various needful places.
- Replace abuse of pcq by a lock and a tailq.
(pcq is multi-producer, _single_-consumer, but there are potentially
multiple consumers here and really only one producer.)
- Teach ld_sdmmc to abort xfers on detach.
(Mechanism is kinda kludgey but it'll do for now; any effort one is
tempted to spend overhauling this should be spent overhauling sdmmc
to support proper asynchronous commands.)
- Make sure ld_sdmmc_discard either returns failure or eventually calls
ldenddiscard.
XXX Currently ld_sdmmc_detach aborts xfers _before_ ldbegindetach has
has committed to detaching or not. This is currently necessary to
avoid a deadlock because ldbegindetach waits for xfers to drain --
which strikes me as wrong; ldbegindetach shouldn't wait for anything,
and should only make the decision to commit to detaching or not so
the caller can decide whether to abort xfers before we actually wait
for them in ldenddetach.
XXX pullup -- although this changes some kernel symbols (sdmmc_add_task
and sdmmc_del_task), it shouldn't affect any existing modules; the only
module that uses sdmmc is ld_sdmmc.kmod, which is `.if 0' in the build
so there shouldn't be any of them floating around.
Make this work on big endian machines
move some of the patching of callbacks and other data after
ieee80211_ifattach() but before if_deferred_start_init().
may fix panic i saw in after restarting wpa_supplicant.
from mlelstv.
only ask for SDPCMD_INTSTATUS_HMB_SW_MASK and SDPCMD_INTSTATUS_CHIPACTIVE
interrupts, not all of them. we only ack these ones.
mostly fixes pinebookpro wifi hard hangs. still is problematic and can
trigger interrupt storm that appears as a hard hang without NET_MPSAFE,
and a follow up, less clearly right, change will reduce that to a soft
hang of the interface that can be cleared with 'ifconfig bwfm0 down up',
and even often recovers itself now.
clear all interrupts, not just those we expect from the hostintmask.
this removes the final hard hang i have seen in pinebookpro wifi,
though one may still need to 'ifconfig bwfm0 down up' occasionally,
so we still have bugs to fix here (the hang is usually associated
with 'checksum error' from bwfm/sdio.)
