* Init error to 0 for sdmmc_mem_single_{read,write}_blockjsg2015-04-221-3/+3

| | | | | | bluetooth support doesn't work and isn't going anywhere. the current design is a dead end, and should not be the basis for any future support. general consensus says to whack it so as to not mislead the unwary.
* Raise the delay before initializing sdmmc. Still a hack so the XXX stays,sthen2014-03-051-2/+2
| | | | | but at least lets the reader on X220 work pretty reliably, rather than about 1/4 of the time. ok stsp@

| | | | | | | | kernel resumes normal (non-cold, able to run processes, etc) operation. Previously we were relying on specific DVACT_RESUME op's in drivers creating callback/threads themselves, but that has become too common, indicating the need for a built-in mechanism. ok dlg kettenis, tested by a sufficient amount of people

* Add code for SMC_CAPS_SINGLE_ONLY capability.syl2013-10-221-8/+83
| | | | | | | | | This capability force the sdmmc stack to only issue single blocks transfers. tested by rapha@ and I on ommmc(4). tested by rapha@ on pxammc(4). ok rapha@
* Add basic support for eMMC memory.rapha2013-09-125-11/+214
| | | | | | | | Heavily based on netbsd. Tested by dlg@, bcallah@ (sdhc), stsp@ (rstx) and me (ommmc). ok patrick@

* Revamp the sequences for suspend/hibernate -> resume so that the codederaadt2012-10-081-1/+5
| | | | | | | | | | paths are reflexive. It is now possible to fail part-way through a suspend sequence, and recover along the resume code path. Split DVACT_SUSPEND by adding a new DVACT_POWERDOWN method is used after hibernate (and suspend too) to finish the job. Some drivers must be converted at the same time to use this instead of shutdown hooks (the others will follow at a later time) ok kettenis mlarkin

* Fixed config_pending calls in sdmmc(4)uwe2011-11-102-8/+11
| | | | | | | | Root on SD/MMC card did not work reliably because the config_pending state was cleared too early. This change will clear config_pending only after the card discovery has actually completed once. ok deraadt@ drahn@
* Add support for the Ricoh 5U823 SD/MMC controller found on the x220.kettenis2011-07-312-6/+6

* Simplify sdmmc_scsi by using SCSI_NO_ADAPTER_TARGET.matthew2011-07-091-10/+9
| | | | Tested by drahn@
* Kludge around sdmmc(4)'s poor design: replace "struct scsi_link *"matthew2011-07-092-5/+5

* Add DVACT_QUIECE support. This is called before splhigh() and beforederaadt2010-08-311-1/+4
| | | | | | | | DVACT_SUSPEND, therefore DVACT_QUIECE can do standard sleeping operations to get ready. Discussed quite a while back with kettenis and jakemsr, oga suddenly needed it as well and wrote half of it, so it was time to finish it. proofread by miod.

* kill PWR_STANDBY (apm can use PWR_SUSPEND instead). While here, renumberderaadt2010-08-271-2/+1
| | | | | | | PWR_{SUSPEND,RESUME} so that they match the values of DAVCT_{SUSPEND,RESUME} so that we can eventually (many more steps...) kill the powerhook garbage and use the activate mechanism. no objections

* m_copyback can fail to allocate memory, but is a void fucntion so gymnasticsblambert2010-07-021-2/+2

| | | | | | | low-hanging splbio/splx pairs that are no longer needed and see if this reveals any hidden scsi flaws. ok dlg@
* Change the scsi_cmd function member of scsi_adapter from int tokrw2010-03-231-15/+14
| | | | | | | | | | | | | void. Use XS_NO_CCB error in the scsi command (xs) to report the NO_CCB condition. Eliminates all SUCCESSFULLY_QUEUED and COMPLETE confusion and untangles the midlayer from the adapter a bit more. Eyes and some fixes by miod@ There may be some compile issues on little used (i.e. I don't have any) drivers but the change is mechanical and thus easy to remedy. ok dlg@
* No need for M_CANFAIL if M_NOWAIT is used. Found by Gleydson Soares.claudio2010-02-111-2/+2

* Let the sdmmc adapters tell the sdmmc layer how much sectors they canmiod2009-02-205-16/+25
| | | | | | | | transfer with one command. Build on this and the recent minphys() changes in the sdmmc layer to crank transfers at the maximum possible size instead of a sad DEV_BSIZE. Depending on your controller, this can speed up sdmmc I/O up to 2.5 times.
