* block: separate priority boosting from REQ_METAChristoph Hellwig2016-06-051-0/+3
| | | | | | | | | | | | Add a new REQ_PRIO to let requests preempt others in the cfq I/O schedule, and lave REQ_META purely for marking requests as metadata in blktrace. All existing callers of REQ_META except for XFS are updated to also set REQ_PRIO for now.

* mmc: core: Kill block requests if card is removedSujit Reddy Thumma2011-11-231-0/+5
| | | | | | | | | | | | | | Kill block requests when the host knows that the card is removed from the slot and is sure that subsequent requests are bound to fail. Do this silently so that the block layer doesn't output unnecessary error messages. This patch implements suggestion from Adrian Hunter, http://thread.gmane.org/gmane.linux.kernel.mmc/2714/focus=3474 Change-Id: I146299b4acbcce95f9cfac114ee3feb56d1a13bd Signed-off-by: Sujit Reddy Thumma <sthumma <at> codeaurora.org> Signed-off-by: David Taylor <x0158378@ti.com>

* mmc: block: improve error recovery from command channel errorsRussell King - ARM Linux2011-10-261-50/+182
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Command channel errors fall into four classes: 1. The command was issued with the card in the wrong state 2. The command failed to be received by the card correctly 3. The cards response failed to be received by the host (CRC error) 4. The card failed to respond to the card For (1), in theory we should know that the card is in the correct state. However, a failed stop command (or other failure) may result in the card remaining in a data transfer state from the previous command. If we detect this condition, we try to recover by sending a stop command. For the initial commands (set block count and the read/write command) no data will have been transferred. All that we need deal with is retrying at this point. A failed stop command can be remedied as above. If we are unable to recover the card (eg, the card ignores our requests for status, or we don't recognise the error code) then we immediately fail the request.

| | | | | | | | | | | | | | | | | | | | | | | | | | SCSI defines discard alignment as the offset to the first optimal discard. In the case of SD/MMC, that is always zero which is the default. SCSI defines discard granularity as a hint of a optimal discard size. That is much better expressed by the MMC "preferred erase size" (pref_erase) field.

* mmc: core: Add mmc CMD+ACMD passthrough ioctlJohn Calixto2011-05-241-0/+201
| | | | | | | | | | | | | | | | | | | | | | | | Allows appropriately-privileged applications to send CMD (normal) and ACMD (application-specific; preceded with CMD55) commands to cards/devices on the mmc bus. This is primarily useful for enabling the security functionality built in to every SD card. It can also be used as a generic passthrough (e.g. to enable virtual machines to control mmc bus devices directly). However, this use case has not been tested rigorously. Generic passthrough testing was only conducted for a few non-security opcodes to prove the feasibility of the passthrough. Since any opcode can be sent using this passthrough, it is very possible to render the card/device unusable. Applications that use this ioctl must have CAP_SYS_RAWIO. Security commands tested on TI PCIxx12 (SDHCI), Sigma Designs SMP8652 SoC, TI OMAP3621/OMAP3630 SoC, Samsung S5PC110 SoC, Qualcomm MSM7200A SoC.

* mmc: make number of mmcblk minors configurableOlof Johansson2010-10-252-12/+48
| | | | | | | | | | | | | | | | | | | The old limit of number of minor numbers per mmcblk device was hardcoded at 8. This isn't enough for some of the more elaborate partitioning schemes, for example those used by Chrome OS. Since there might be a bunch of systems out there with static /dev contents that relies on the old numbering scheme, let's make it a build-time option with the default set to the previous 8. Also provide a boot/modprobe-time parameter to override the config default: mmcblk.perdev_minors.

| | | | | | | | Usually there are multiple mmc host controllers; rename mmc queue thread by host index so we can easily identify which controller it belongs to. Signed-off-by: Ethan Du <ethan.too@gmail.com> Signed-off-by: Chris Ball <cjb@laptop.org>
