| | | | | | | | | | | | a DRIVER_MODULE() referencing mmc_driver has a MODULE_DEPEND() on mmc. This is because the kernel linker only searches for symbols in dependent modules, so loading sdhci_pci (and other bus-flavors of sdhci) would fail when mmc was not compiled into the kernel (even if you hand-loaded mmc first). (Thanks to jilles@ for providing the vital clue about the kernel linker.) Notes: svn path=/head/; revision=297127

| | | | | | | | | | | | for all struct bio you get back from g_{new,alloc}_bio. Temporary bios that you create on the stack or elsewhere should use this before first use of the bio, and between uses of the bio. At the moment, it is nothing more than a wrapper around bzero, but that may change in the future. The wrapper also removes one place where we encode the size of struct bio in the KBI.

Also, error reporting is limited to 5 events per second, because when an sdcard goes bad on a low-end embedded board, flooding the console at high speed isn't helpful.

* fwsectors and fwheads used to be somehwat arbitrary. However, they areWarner Losh2014-10-161-1/+23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | used to align partitions in gpart. We also try to align partitions by stripe size when creating new media. Align these two concepts by making fwsectors the same as the stripe size. Select a sensible number of heads so we wind up with about 20 cylinders. This number was selected to keep the rounding effects to a few percent while keeping the number of cylinder groups low. Sadly, it is not possible to make these numbers match the numbers used by SD card readers. There apperas to be much variation between brands so there's no one universal number. These numbers are also not aligned to the stripe size, so some performance problems may still be present when SD cards are created this way. Also, these numbers will differ from the far less common SD to ATA adapters, which present a different, but more uniform, set of numbers that also happened to match the old defaults. Nothing should change for current users. Any suboptimal performance caused by misalignment will still be there. gpart will honor the partitions that aren't on proper boudnaries, but editing the partition tables may result in different alignments being used than before when editing things natively. Ideally, there'd be some way to override these values in the disk subsystem by the user for the USB adapter use case where all "native" notions of geometry disappear. This does not implement that.

* Make the standard sdhci(4) driver work for the TI OMAP family SoCs.Ian Lepore2013-08-201-0/+1
| | | | | | | | | | | | | | | | | The MMCHS hardware is pretty much a standard SDHCI v2.0 controller with a couple quirks, which are now supported by sdhci(4) as of r254507. This should work for all TI SoCs that use the MMCHS hardware, but it has only been tested on AM335x right now, so this enables it on those platforms but leaves the existing ti_mmchs driver in place for other OMAP variants until they can be tested. This initial incarnation lacks DMA support (coming soon). Even without it this improves performance pretty noticibly over the ti_mmchs driver, primarily because it now does multiblock IO.

* Consistently init all mmc request, command, and data structures to zeroIan Lepore2013-08-172-10/+27

* Handle command retries for commands originating at the mmc layer, andIan Lepore2013-08-161-32/+41
| | | | | | | | | | | | | | | | | | | | | | | ensure that all such commands have a non-zero retry count except for those that are expected to fail (for example, because they are used to probe for feature support). While it is possible to pass a retry count down to the hardware driver in the command request structure, no hardware driver currently implements any retry logic. The hardware doesn't know much about the context of a single request, so it makes more sense to handle retries at a layer that does. This adds retry loops to the mmc_wait_for_cmd() and mmc_wait_for_app_cmd() functions. These functions are the gateway from other code within mmc.c to the hardware. App commands are a sequence of two commands and a retry has to rerun both of them in order, so it needs its own retry loop. Retry looping is specifically NOT implemented in mmc_wait_for_request() because it is the gateway for children on the bus, and they have to implement their own retry logic depending on what makes sense for them.
