Store the bus cookie in the mmc_disk driver and pass it to the bus manager when executing commands. This avoids calling into the device manager at each read and write operation. The code to get the cookie from mmc_disk isn't so nice since it needs to access the grandparent device (the mmc bus root), it would be simpler if this cookie would be available directly from mmc bus devices. We can get card removal and card insertion interrupt at the same time due to insufficient hardware debouncing (the SDHCI spec says we shouldn't, but it happens on Ricoh controllers. Can't blame them, they don't advertise themselves as compliant with the spec). So, check the card status from the interrupt handler and ignore the incorrect interrupts. Fix unreliable card initialization: power must be turned on before starting up the SD clock. Remove a now unneeded delay that was added in an attempt to avoid initial instability.

Haiku
Homepage | Mailing Lists | IRC Channels | Issue Tracker | API docs
Haiku is an open-source operating system that specifically targets personal computing. Inspired by the BeOS, Haiku is fast, simple to use, easy to learn and yet very powerful.
Goals
- Sensible defaults with minimal configuration required.
- Clean, clear, concise code.
- Unified desktop environment.
Trying Haiku
Haiku provides pre-built nightly images and release images. Haiku is compatible with a large variety of hardware, but in case you don't want to "take the plunge" and install Haiku on bare metal, you can install it on a virtual machine (VM) instead. If you've never used a VM before, you can follow one of the "Emulating Haiku" guides.
Compiling Haiku
See ReadMe.Compiling
.
Contributing
Haiku is a meritocratic open source project with a large variety of tasks. Even if you can't write code, you can still help! Haiku needs designers, (technical) writers, translators, testers... Get involved and help out!
