 1.44  24-Jun-2025  gutteridge sdmmc.c: add missing newlines to several device_printf(9) calls
 1.43  07-Aug-2021  thorpej branches: 1.43.12;
Merge thorpej-cfargs2.
 1.42  13-Jun-2021  mlelstv branches: 1.42.2;
Don't crash on detach where interlock == NULL.
 1.41  24-Apr-2021  thorpej branches: 1.41.2;
Merge thorpej-cfargs branch:

Simplify and make extensible the config_search() / config_found() /
config_attach() interfaces: rather than having different variants for
which arguments you want pass along, just have a single call that
takes a variadic list of tag-value arguments.

Adjust all call sites:
- Simplify wherever possible; don't pass along arguments that aren't
actually needed.
- Don't be explicit about what interface attribute is attaching if
the device only has one. (More simplification.)
- Add a config_probe() function to be used in indirect configuiration
situations, making is visibly easier to see when indirect config is
in play, and allowing for future change in semantics. (As of now,
this is just a wrapper around config_match(), but that is an
implementation detail.)

Remove unnecessary or redundant interface attributes where they're not
needed.

There are currently 5 "cfargs" defined:
- CFARG_SUBMATCH (submatch function for direct config)
- CFARG_SEARCH (search function for indirect config)
- CFARG_IATTR (interface attribte)
- CFARG_LOCATORS (locators array)
- CFARG_DEVHANDLE (devhandle_t - wraps OFW, ACPI, etc. handles)

...and a sentinel value CFARG_EOL.

Add some extra sanity checking to ensure that interface attributes
aren't ambiguous.

Use CFARG_DEVHANDLE in MI FDT, OFW, and ACPI code, and macppc and shark
ports to associate those device handles with device_t instance. This
will trickle trough to more places over time (need back-end for pre-OFW
Sun OBP; any others?).
 1.40  24-May-2020  riastradh branches: 1.40.4;
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.
 1.39  28-Oct-2019  mlelstv Add and use sdmmc_pause to avoid long-term busy waits.
Add sdio abort function.
Additional error messages.
Print parameters for SDIO devices.
Minor cosmetics.
 1.38  23-Oct-2019  hkenken Add SDHC flags.

+ SDHC_FLAG_BROKEN_ADMA2_ZEROLEN
Broken ADMA2 Zero length descriptor.
Can't 64K Byte data transfer.
+ SDHC_FLAG_NO_1_8_V
Support no 1.8V Supply.
Disable UHS-I bus speed mode (SDR50, DDR50, SDR104).
 1.37  01-Sep-2019  mlelstv From OpenBSD:
- support block length per function
- add functions to read/write regions
Decode (but not use) SDIO tuple in CIS.
Fix locking.
Add more SDIO defines (partially from version 3.0).
 1.36  06-Nov-2018  jmcneill branches: 1.36.4;
Increase kthread priority to PRI_SOFTBIO.
 1.35  06-Mar-2018  mlelstv branches: 1.35.2;
correct whitespace in attach message
 1.34  17-Feb-2017  nonaka branches: 1.34.12;
sdhc(4): hardware reset support for Intel eMMC controller
 1.33  22-Dec-2015  mlelstv branches: 1.33.2; 1.33.4;
ignore timeouts for APP_CMD prefix as for the application command itself.
 1.32  29-Nov-2015  jmcneill Add some event counters to track transfer sizes.
 1.31  09-Aug-2015  mlelstv Send an explicit CMD12 (stop transmission) when there was an error
in multi-sector I/O.

The SDHC spec has a complex flowchart describing when an explicit
CMD12 is necessary, so we probably use it too often.
 1.30  09-Aug-2015  mlelstv protect card detection with mutex.
 1.29  03-Aug-2015  jmcneill Add support for DDR50 transfer modes.
 1.28  03-Aug-2015  mlelstv use mutex locking for MP safety.
 1.27  28-Jul-2015  mlelstv Be more verbose about errors.
 1.26  21-May-2015  jmcneill sdmmc_task_thread isn't MPSAFE so instead of just wrapping the callback
in KERNEL_LOCK/KERNEL_UNLOCK_ONE, remove KTHREAD_MPSAFE. While here, use
PRI_BIO instead of PRI_NONE for the task thread priority. Since this is
how all transfers are queued, and we have a 1 second timeout on the task
being picked up off the queue (!), better not to rely on a PRI_NONE thread.
 1.25  20-May-2015  jmcneill need to call lddone with splbio and kernel lock held
 1.24  27-Feb-2015  nonaka fix to simulate multi-segment dma transfer for pq3sdhc(4).
 1.23  16-Nov-2014  ozaki-r branches: 1.23.2;
Replace callout_stop with callout_halt

In order to call callout_destroy for a callout safely, we have to ensure
the function of the callout is not running and pending. To do so, we should
use callout_halt, not callout_stop.

Discussed with martin@ and riastradh@.
 1.22  19-Mar-2014  nonaka branches: 1.22.4;
Add a driver for Realtek RTS5209/RTS5229 Card Reader.
Ported from OpenBSD.
 1.21  12-Oct-2013  christos Pass the device name in, so we can debug what deferred drivers did not work.
 1.20  22-Dec-2012  jakllsch branches: 1.20.2;
We can't block our interrupt while sdmmc_detach_card is called, as
it can issue commands, and some host drivers have interrupt-driven
command completion. Prevents assertion (or deadlock) upon detach
of sdhc(4) with inserted card.
 1.19  22-Dec-2012  jakllsch Revert sdmmc.c r1.18 (previous commit to this file).
It seems to have caused regressions to detaching drivers from cards at
the appropriate time.

DETACH_FORCE to sdmmc_card_detach really means the SD/SDIO card is gone,
and can not be abused to mean that the host controller disappered.
 1.18  20-Dec-2012  jakllsch Only use DETACH_FORCE as flags argument to sdmmc_card_detach when the
host controller has disappeared or is detaching.
XXX should pass flags from sdmmc_detach through to the task thread ending
to differentiate host controller disappearance from mere detachment.
 1.17  15-Dec-2012  jakllsch It's also useful to compile-test before committing.
 1.16  15-Dec-2012  jakllsch When debugging, it's useful to know what exactly failed.
 1.15  04-Aug-2012  kiyohara branches: 1.15.2;
Print 'Standard Function Interface Code" in sdmmc_print(), if not SD_IO_SFIC_NO_STANDARD.
 1.14  17-Jul-2012  skrll Whitespace.
 1.13  12-Jul-2012  jakllsch If necessary, unload and destroy dmamap upon detach.
 1.12  01-Feb-2012  matt Use "opt_sdmmc.h" for SDMMC_DEBUG, etc.
 1.11  26-Jan-2012  matt Print error if couldn't enable card.
 1.10  21-Jan-2012  nonaka fix my license notice.
 1.9  20-Mar-2011  nonaka branches: 1.9.4; 1.9.8;
if poll card detect is enabled, don't show "couldn't enable card".
 1.8  13-Feb-2011  nonaka - Don't switch MMC high-speed timing, if host controller isn't supported.
- Only check EXT_CSD STRUCTURE version when CSD version is 3.
- initialize width at sdmmc_function_alloc().
 1.7  05-Feb-2011  nonaka Don't switch SD high-speed timing, if host controller isn't supported.
 1.6  07-Oct-2010  kiyohara branches: 1.6.2; 1.6.4;
Fix read CIS. And pass to attach args the standard function interface code.
 1.5  07-Oct-2010  kiyohara Support High-Speed mode.
 1.4  01-Oct-2010  kiyohara Use DMA bounce buffer, if DMA buffer is making by multiple segments. A lot
of host controllers do not support to two or more segments.
 1.3  20-Sep-2010  kiyohara Clear SMF_CARD_PRESENT, if failed to attach.
 1.2  06-Apr-2010  nonaka branches: 1.2.2;

Kill sme_callout_mtx and use sme_mtx instead
We can use sme_mtx for the callout as well. Actually we should do so

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.

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.)

Sort #includes. Nix trailing whitespace.
No functional change intended.

add PCMCIA_CISTPL_SDIO definition.
-
From OpenBSD:
- move event handling to workqueue
- check for save/restore capability
-
Tag work queue as MPsafe and increase length.
-
Juse use bpf_mtap(), the 802.11 encapsulation is handled by firmware.
-
From OpenBSD:
- support block length per function
- add functions to read/write regions
-
Decode (but not use) SDIO tuple in CIS.
-
Fix locking.
-
Add more SDIO defines (partially from version 3.0).
-
From OpenBSD:
- All the missing pieces (firmware load, chip setup, protocol handling)
TX queue and interrupt handling via sdmmc_task.
-
Fix locking.
-
Fix packet parsing.
-
Add parser for original firmware config files.
-
tagging work queue as MPSAFE was premature. Revert.
-
SD_IO_RW_EXTENDED is a data transfer command, so set ADTC flag instead of AC
Use correct function to verify if a task has been queued. Avoids race
that can corrupt the task queue.
-
More register definitions.
-
Add IFM_IEEE80211_VHT subtype, IFM_IEEE80211_11AC operating mode, and missing descriptions
-
If firmware is connected in HT or VHT mode, report it to SIOCGIFMEDIA
-
white space police.

Skip setting power when the voltage doesn't change.
Also increase some timeouts.
-
Add and use sdmmc_pause to avoid long-term busy waits.
-
Add sdio abort function.
-
Additional error messages.
-
Print parameters for SDIO devices.
-
Minor cosmetics.
-
Simplyfy sdmmc_io_set_blocklen function signature by dropping the
extra softc pointer. Aligns with OpenBSD.
-
Missing commit for sdio abort function.
-
More code from OpenBSD
-
no need to splnet() when enqueing packets
-
explicit structure padding
-
make internal functions static
-
also prepare for GPIO interrupts.
-
Avoid warnings for tautological shifts as sole conditional.
-
Follow the Linux driver an use the FDT "compatible" property to build a
filename for the nvram config file, fall back to the standard filename.

-
Add product ID for Broadcom BCM43455
-
Use correct firmware for BCM43456
-
size check was backwards.
-
Be less noisy for some commands.
-
Fix DWC_MMC_INT_SDIO_INT bit
-
dwc_mmc fixes:
- Rockchip uses a different SDIO int bit, so take this into consideration
- Avoid unnecessary resets and always wait for resets to complete
- kpause instead of delay while holding spinlock
- Do not attempt autostop for SD_IO_RW_EXTENDED commands
- Allow for sub-blklen byte counts for single block transfers
-
More SDIO stability and performance fixes
