[PATCH 0/2] hw/block/nvme: oncs and write uncorrectable support

2021-02-09 Thread Klaus Jensen
From: Klaus Jensen First, add support for toggling optional features through the new `oncs` nvme device parameter. Secondly, add support for the Write Uncorrectable command. Gollu Appalanaidu (2): hw/block/nvme: add oncs device parameter hw/block/nvme: add write uncorrectable command

[PATCH 1/2] hw/block/nvme: add oncs device parameter

2021-02-09 Thread Klaus Jensen
From: Gollu Appalanaidu Add the 'oncs' nvme device parameter to allow optional features to be enabled/disabled explicitly. Since most of these are optional commands, make the CSE log pages dynamic to account for the value of ONCS. Signed-off-by: Gollu Appalanaidu Signed-off-by: Klaus Jensen

[PATCH 2/2] hw/block/nvme: add write uncorrectable command

2021-02-09 Thread Klaus Jensen
From: Gollu Appalanaidu Add support for marking blocks invalid with the Write Uncorrectable command. Block status is tracked in a (non-persistent) bitmap that is checked on all reads and written to on all writes. This is potentially expensive, so keep Write Uncorrectable disabled by default.
