This SOFTWARE LICENSE AGREEMENT (this “Agreement”) is entered into between Intel Corporation, a Delaware corporation (“Intel”) and You. If You do not agree to be bound by, or the entity for whose benefit You act has not authorized You to accept, these terms and conditions, do not install, access, copy, or use the Software and destroy all copies of the Software in Your possession. BY INSTALLING, COPYING, ACCESSING, OR USING THE SOFTWARE, YOU AGREE TO BE LEGALLY BOUND BY THE TERMS AND CONDITIONS OF THIS AGREEMENT. Pull requests are very welcome, specially to add support for chips other than RTS525A (the only chip I can test).Document SOFTWARE LICENSE AGREEMENT DO NOT DOWNLOAD, INSTALL, ACCESS, COPY, OR USE ANY PORTION OF THE SOFTWARE UNTIL YOU HAVE READ AND ACCEPTED THE TERMS AND CONDITIONS OF THIS AGREEMENT.

Prevent namespace pollution (OpenBSD functions pollute the namespace and may cause collisions).

Use command gate instead of two workloops? Is it even possible?.

Troubleshoot why after a soft reboot, for chip 525A version B, chip version is detected as 'A'.

DRIVERS FOR SD CARD READER UPDATE

If adding the rtsx_sleep_wake_delay_ms=1000 boot parameter solves your sleep/wake issues, and your chip is not RTS5227, please let me know so that I can update the above table. For other chips, the card may become unreadable upon wake. This is the expected behavior and it should work at least for chip RTS525A. The card is unmounted on sleep and remounted on wake. Some user-level program (HWMonitor is one of them) may hold references to a class in this kext that would prevent unloading.You should be able to unload the kext using the command kextunload -c Sinetek_rtsx.

This limitation comes from the OpenBSD driver on which this kext is based and I do not have any plan to fix it. The driver only supports up to High-Speed mode, meaning that UHS-I and higher cards will only work as HS. Introduce a delay on sleep/wake that may help with some chips like RTS5227. May help with some slow cards (i.e.: rtsx_timeout_shift=2). Disabled by default.ĭo some extra initialization which may be useful if your chip is exactly RTS525A version B (exactly the same as mine). Does not seem to make any difference in speed. Issue an ACMD23 before a multiblock write. Use IOMalloc/ IOFree for memory management instead of new/ delete. This should use more locks to protect critical sections.Ī try to make IOCommandGate working, but never really worked.

The code allows some customization by defining/undefining certain preprocessor macros (set on ): Option

Since there may be more than one task pending, a new task struct must be allocated/freed for each new task.

Fixed a bug where a single task member was being reused.

Use IOFilterInterruptEventSource instead of IOInterruptEventSource (should give better performance).

The benefit this brings is that the future improvements in the OpenBSD driver can be incorporated more easily. This implied rewriting all OpenBSD functions which are not available in Darwin so that the same behavior is obtained using only functions available in the macOS kernel.

An OpenBSD-compatibility layer has been added to make the original OpenBSD driver work with as few changes as possible.

If you have a chip other than RTS525A and this kext is working for you, please let me know and I will update this table. Enabling sleep may make the kext unstable. Not working after sleep and wakes up sleep constantly.Īdding boot parameter rtsx_sleep_wake_delay_ms=1000 makes it work with sleep enabled. Adding boot parameter rtsx_sleep_wake_delay_ms=1000 may help with sleep/wake. This does not apply to other chips, which may have a very unstable behavior or not work at all.

Currently, stability for RTS525A has been improved up to a usable level.

My hope is that this driver gets improved over time and that these changes can be incorporated here.

It seems that the OpenBSD driver is still in a very rough state.

I'm not sure whether this approach is right or not (an IOCommandGate with one single workloop seems the way to go), but for now it seems to work. The solution adopted is to have two workloops, the normal workloop_ and a separate workloop for tasks.

We needed a way to wait for the interrupt while in workloop_.

It took me a while to understand the code. All credits are due to the original authors, and Overall notes This is a try to make this kext working on my laptop (Dell XPS 9350).
