Thank you, V0.9.3v3 works, and like you mentioned it doesn't show up in system profiler, but it does in IORegistryExplorer and I tested with 2 cards, here are my results.

 

Did a read/write stress test copying a 1GB file then copying the copy, and so on 10 times and then compared checksum to the original and data was identical.

The write speed was between 12MB/S ~ 22MB/S on both cards.

The read speed was ~50MB/s on one card and ~ 70MB/S on the other.

The card reader has problems ejecting a card if the laptop goes to sleep with a card loaded/mounted.

The card reader does not load a card after waking the laptop from sleep. (tested fresh boot->sleep->wake->load card... nothing)

Kext only tested in Catalina, will not load in Mojave.

Thanks for your test report.

Most cards have slower write speed.

Did you test your card under other systems?

Are the statistics under macOS similar to those under other systems?

Expected, because power management is not implemented yet.

The card needs to be reinitialized after the computer wakes up, so stay tuned. :)

Thanks for this driver. I tried it with the RTS522a controller, but  the card initialization fails. See the log. 

 

@wern apfel Your card did not respond to the CMD2 after being switched to 1.8V,

probably because I forgot to set the driving tables for RTS5227 and RTS522A.

 

Please try 0.9.3v4 and see if it resolves the issue.

If not, please attach the kernel log.

The write results are pretty much the same across MacOS Windows and Linux. ~15MB/s

For the 70~75MB/s Card:

Read for Linux is ~80MB/s

Read for Windows is ~85MB/s.

 

It's possible the debug version limits the performance a bit, but overall it's great! can't wait for PM and older versions if possible!

 

Cheers!

v0.9.4 beta comes with basic power management support.

Link: https://github.com/0xFireWolf/RealtekPCIeCardReader/releases/tag/v0.9.4

 

Please focus on the following scenarios:

 

1) Put the machine to sleep without the card inserted.

Wake up your machine and insert the SD card.

Check whether the card can be recognized and work properly.

 

2) Put the machine to sleep with the card inserted.

Wake up your machine and check whether your SD card shows up.

If not, remove the card and insert it again and see whether the card can be recognized and work properly.

 

In my case, the SD card was initialized properly under macOS Big Sur and Catalina, but the system ejected the card after the machine waked up.

I have to remove the card and insert it back. However, the SD card showed up and was not ejected by the system under macOS Mojave.

Overall, the driver is pretty stable now on my machine with RTS525A.

 

@theroadw I tested the driver under macOS Mojave and it is working fine on my machine. Please give it a try.

Tested and it works correctly in both Catalina and Mojave.

In both OS the card would not show up on wake, and in Mojave there will be a "device not ejected" notification, but removing and re-inserting the card worked on both.

 

Some odd behavior, in Catalina is that I could remove the drive without ejecting first without any notification, in Mojave the system alerted me of first ejecting the drive, don't know if this is normal.

Also on Mojave I got a early KP when I switched to the Release Version, but the next reboot was fine.

 

Speed is ~13MB/s write and 83MB/s read, awesome!!! Thank you for this Kext.

The project has been rebranded. :)

 

v0.9.5 beta comes with support for USB-based RTS5129, RTS5139 and RTS5179 card readers.

@b0ltun For those who have aforementioned chips, please give a try and report any issues, as I don't have the hardware to test with.

 

The bonus feature has been reenabled, but you need to the install the companion Lilu plugin (https://github.com/0xFireWolf/RealtekCardReaderFriend).

Check the main post or the repo for details.

I have tried v0.9.5 beta with RTS5129 and the kext doesn't seem to load.

 

I forgot to add: the log with boot-arg and DebugEnhancer is empty.


When did you dump your attached IOReg report? Before or after inserting a SD card?


I check your IOReg and surprisingly found that your card reader does not publish the host interface required by this driver.

 

Does the driver load after you insert the card? If not, please attach the IOReg report and the kernel log (if not empty).

The attached IOReg report was before inserting the card I think.

I'm attaching new reports as you requested. The log is still empty.

IOReg.zip

 

I wonder if this would help.

1. IOReg report from a year ago of a machine with RTS5138 which is natively supported. This I believe is before inserting the card.

2. Alcor 058f6366, works natively. https://www.dropbox.com/s/ykx69y9e6bl379n/2.zip?dl=0

Thank you for the IOReg reports. They are really helpful, and I think I have found the issue.

 

The driver needs to attach to the USB host device itself and find the interface manually

instead of dreaming that someone will create an interface for it. :star_smile:

 

That's why the driver never gets loaded and you cannot find the log.

 

Stay tuned. :cowboy:

Hi Sherlocks,

 

Could you please attach the IOReg reports before and after you insert the card?

 

Thanks.

@Sherlocks Really interesting. Your IOReg dump shows that your RTS5129 has already been configured and exposed the host interface,

while @whatnameisit's card reader needs to be configured by the driver manually.

 

Anyway, I have changed the matching dictionary, so the driver should attach to the host device and configure the card reader if necessary,

so @whatnameisit please try this one.

 

In addition, @Sherlocks the driver cannot find bulk endpoints of your card reader,

probably because their addresses are not the same as the ones on Linux.

I have updated the code to search for them instead of using hard-coded constants from the Linux driver.

Please give a try. I really want to chat with you to speed up testing the driver, but unfortunately I am not available today.

I expect that the driver is buggy since I do not have any USB-based card readers to test with.

Good, the driver attached to the host device successfully, but I made some stupid and fatal typos in the hardware initialization routine. Try this one.

here is log

Thank you guys for detailed test reports.

 

@Sherlocks It seems that you inserted a non-UHS-I card, so the driver tried to initialize your card at the high speed mode but failed the very last step that switches the bus width to 4-bit. Specifically, the driver was timed out while waiting for the card response to the ACMD6 command. I recalled that the same issue occurred on some RTS5227 chips, but their kernel logs are incomplete, so I am not too sure about that. I don't really have a clue at this moment, but maybe we could try to initialize the card with 1-bit data line and see if things work.

 

RealtekCardReader_0.9.6_3523d8d_1BitBusWidth_DEBUG.zip

 

----------------------------------------------------------------

 

@whatnameisit @b0ltun It seems that both of you inserted the card after the system boots. My previous assumption that the card reader gets connected to the system only when a card is inserted is wrong, so the driver cannot detect any card events after it has started. Please try this one and see if it works when you insert the card AFTER the system boots.

 

RealtekCardReader_0.9.6_3523d8d_DEBUG.zip

 

@b0ltun Regarding to the issue that the card reader is not listed in System Information, I forgot to inject the physical interconnect property to the controller.

Check if you can see the card reader with the above kext.

@Austere.J will test it now, actually i did insert card only after system fully booted before. I will check it now.

 

P.S. Now it's kinda shown in system report, heh

 

Still no card showing after inserting it, i will attach log

(Booted, inserted card, checked, took log)

OK, I see. You encountered the same issue as Sherlocks.

 

Please try the above 1-bit version with your card inserted while the system boots.
