9.0

Main changes:

1. Set CURRENT_PROJECT_VERSION/MARKETING_VERSION = MODULE_VERSION (closes #26)
2. Version bumped to 9.0.0, even though there are no code changes, just to prevent CURRENT_PROJECT_VERSION from being lower than the previous one.

2.5

Main changes:

1. Use macOS SD-Card icon instead of the generic one (PR #21, credits to @ffosilva).

Tested and working on Mojave and Big Sur. Should also work on High Sierra and Catalina.

2.4

Main changes:

1. Merged PR #18 and made delay a boot parameter (rtsx_sleep_wake_delay_ms).

Since the default delay is zero, current uses can upgrade to this new version (nothing has changed unless you use the new boot parameter). Those with chip RTS5227 may get a better sleep/wake behavior by using boot parameter rtsx_sleep_wake_delay_ms=1000, as tested by @CLAY-BIOS.

2.3

Main changes:

1. Use MSI interrupt instead of INTx.
2. ADMA enabled (can be disabled using the -rtsx_no_adma boot parameter).
3. Add boot parameter rtsx_timeout_shift=n to allow for longer timeouts (i.e. rtsx_timeout_shift=1 doubles timeouts).
4. Improve logging of timeouts.
5. RTS525A: Improve stability by adding initialization code from the Linux driver.

2.3-beta2

Main changes:

1. Add boot parameter rtsx_timeout_shift=n to allow for longer timeouts.
2. Improve logging of timeouts.

2.3-beta

Main changes:

1. Use MSI interrupt instead of INTx.
2. ADMA enabled (can be disabled using the -rtsx_no_adma boot parameter).

THIS IS A BETA RELEASE

2.2

Main changes:

1. Kext is now compatible with (at least) macOS 10.13/10.14/10.15.
2. Fixed a bug that was causing corrupt data being read/written for large reads/writes (like picture files).
3. Other fixes (memory leak, null pointer check).

2.1

Main changes:

1. Sleep/Wake implemented.
2. Read-write mode is enabled by default. The boot argument "-rtsx_rw" is removed and now "-rtsx_ro" is used to set the driver to read-only mode.
3. The compile-time define RTSX_MIMIC_LINUX has been removed and now the "-rtsx_mimic_linux" boot argument is used instead.

2.0

Main changes:

• Implement openbsd_compat layer to use OpenBSD code without changes (bus_space, config, dma, kthread, etc.)
• Renamed rtsx_softc IOService to Sinetek_rtsx to keep this structure separate from the main class
• Some code added from the Linux driver to help with chip initialization
• Reduced 1 second timeout to 100 ms to make card mounting faster
• Honor LOCK switch of SD cards
• Add boot parameter (-rtsx_rw) to enable writing
• Improved logging

Initial release

This is the initial try to make this kext working on the Dell XPS 9350/Catalina.

The kext loads, but does not unload. And once a card is inserted/extracted, it stops detecting cards.
