* Fix read_ivar implementation for MMC and SD.jchandra2011-05-302-12/+12
| | | | | | | | | | | 1. Both mmc_read_ivar() and sdhci_read_ivar() use the expression '*(int *)result = val' to assign to result which is uintptr_t *. This does not work on big-endian 64 bit systems. 2. The media_size ivar is declared as 'off_t' which does not fit into uintptr_t in 32bit systems, change this to long. Submitted by: kanthms at netlogicmicro com (initial version)

* Make the newbus subsystem Giant free by adding the new newbus sxlock.attilio2009-08-021-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The newbus lock is responsible for protecting newbus internIal structures, device states and devclass flags. It is necessary to hold it when all such datas are accessed. For the other operations, softc locking should ensure enough protection to avoid races. Newbus lock is automatically held when virtual operations on the device and bus are invoked when loading the driver or when the suspend/resume take place. For other 'spourious' operations trying to access/modify the newbus topology, newbus lock needs to be automatically acquired and dropped. For the moment Giant is also acquired in some key point (modules subsystem) in order to avoid problems before the 8.0 release as module handlers could make assumptions about it. This Giant locking should go just after the release happens. Please keep in mind that the public interface can be expanded in order to provide more support, if there are really necessities at some point and also some bugs could arise as long as the patch needs a bit of further testing. Bump __FreeBSD_version in order to reflect the newbus lock introduction. Reviewed by: ed, hps, jhb, imp, mav, scottl No answer by: ariff, thompsa, yongari Tested by: pho, G.

* Implement suspend/resume for mmc and mmcsd drivers.mav2008-12-062-66/+164
| | | | | | | | | | | Now it is possible to suspend/resume with inserted and active card. To reinitialize card on resume and to detect card change while suspended, implement bus rescan routines. It can also be used by controllers without card presence detection signals or with multiple cards per slot support. While there, cleanup msleep() usage. We have no any rights to exit without "request done" signal from driver as it could lead to modify after free.

* Implement BIO_DELETE command with MMC and SD erase commands.mav2008-10-184-149/+333
| | | | | | | | | | | | | | | | | Erase operation gives card's logic information about unused areas to help it implement wear-leveling with lower overhead comparing to usual writing. Erase is much faster then write and does not depends on data bus speed. Also as result of hitting in-card write logic optimizations I have measured up to 50% performance boost on writing undersized blocks into preerased areas. At the same time there are strict limitations on size and allignment of erase operations. We can erase only blocks aligned to the erase sector size and with size multiple of it. Different cards has different erase sector size which usually varies from 64KB to 4MB. SD cards actually allow to erase smaller blocks, but it is much more expensive as it is implemented via read-erase-write sequence and so not sutable for the BIO_DELETE purposes. Reviewed by: imp@
