| |
Hi,
The device is present in many notebooks. Notebooks depend heavily on suspend/resume functionality. tifm_core/7xx1/sd family is an ambitous, but uncompleted project. It used to crash on resuming, or hang up on suspending. A less common failure used to be trigerred by a fast card insert/removal sequence. Finally, tifm_sd module needs to be manually inserted.
I have found it easier to rewrite the driver, than to fix. This driver is kind of mutant. The bones are taken from sdhci and omap, the meat - from tifm_*. It contains all features (and bugs except named above) of tifm_* as it was in kernel 2.6.21-rc7.
I have been testing this version since linux-2.6.18 (daily reading photos from cards, daily suspending/resuming) without a single glitch.
This patch only provides sources. http://bugzilla.kernel.org/attachment.cgi?id=11238&action=view

Alex Dubov has done exceptionally great lots of work to teach linux speak to TIFM. This is just a reorganization of his project.
The driver seems to be practically stable, but it definitely must be tested by more people. Please also report any issues with this driver to http://bugzilla.kernel.org/show_bug.cgi?id=8352 so that valuable info is not lost.
Best regards, Sergey Yanovich
