Expose the following packed commands tests:
- Test the write packed commands list preparation
- Simulate a returned error code
- Send an invalid packed command to the card
In order to test the eMMC4.5 features, the test-iosched is used.
The test scheduler allows testing a block device by dispatching
specific requests according to the test case and declare PASS/FAIL
according to the requests completion error code.
The write packed commands statistics are used to determine the success or failure of
the packed commands tests, in addition to the generic request completion checking.
This patch is dependant in the following patches:
[PATCH v8 1/3] mmc: core: Add packed command feature of eMMC4.5
[PATCH v8 2/3] mmc: core: Support packed write command for eMMC4.5 device
Changes in v5:
- Code review fixes
Changes in v4:
- Add large sector size alignment to the packed commands stop reason statistics
- Fix error handling in test-iosched
- Code review fixes
Changes in v3:
- Fix the cancel round mechanism
Changes in v2:
- Add MMC write packing statistics and test-iosched scheduler patches as part of this patch.
- Code review fixes
