misc: mic: MIC host and card driver changes to enable VOP

2016-02-10T01:32:37+00:00

This patch modifies the MIC host and card drivers to start using the VOP driver. The MIC host and card drivers now implement the VOP bus operations and register a VOP device on the VOP bus. MIC driver stack documentation is also updated to include the new VOP driver. Reviewed-by: Ashutosh Dixit Signed-off-by: Sudeep Dutt Signed-off-by: Greg Kroah-Hartman

misc: mic: Remove MIC X100 host virtio functionality

2016-02-10T01:32:37+00:00

This patch deletes the virtio functionality from the MIC X100 host driver. A subsequent patch will re-enable this functionality by consolidating the hardware independent logic in a new Virtio over PCIe (VOP) driver.

misc: mic: Remove COSM functionality from the MIC host driver

2015-10-04T11:46:06+00:00

Since COSM functionality is now moved into a separate COSM driver drivers, this patch removes this functionality from the base MIC host driver. The MIC host driver now implements cosm_hw_ops and registers a COSM device which allows the COSM driver to trigger boot/shutdown/reset of the MIC devices via the cosm_hw_ops.

misc: mic: fixup return type of wait_for_completion_timeout

2015-03-25T10:36:38+00:00

return type of wait_for_completion_timeout is unsigned long not int. The rc variable is renamed timeout to reflect its use and the type adjusted to unsigned long. Signed-off-by: Nicholas Mc Guire Acked-by: Sudeep Dutt Signed-off-by: Greg Kroah-Hartman

misc: mic: Fix endianness issues.

2013-11-27T19:03:38+00:00

Endianness issues are now consistent as per the documentation in host/mic_virtio.h. Sparse warnings related to endianness are also fixed. Note that the MIC driver implementation assumes that the host can be both BE or LE whereas the card is always LE.

tree-wide: use reinit_completion instead of INIT_COMPLETION

2013-11-15T00:32:21+00:00

Use this new function to make code more comprehensible, since we are reinitialzing the completion, not initializing.

misc: mic: Enable OSPM suspend and resume support.

2013-10-06T01:01:42+00:00

This patch enables support for OSPM suspend and resume in the MIC driver. During a host suspend event, the driver performs an orderly shutdown of the cards if they are online. Upon resume, any cards that were previously online before suspend are rebooted. The driver performs an orderly shutdown of the card primarily to ensure that applications in the card are terminated and mounted devices are safely un-mounted before the card is powered down in the event of an OSPM suspend. The driver makes use of the MIC daemon to accomplish OSPM suspend and resume. The driver registers a PM notifier per MIC device. The devices get notified synchronously during PM_SUSPEND_PREPARE and PM_POST_SUSPEND phases. During the PM_SUSPEND_PREPARE phase, the driver performs one of the following three tasks. 1) If the card is 'offline', the driver sets the card to a 'suspended' state and returns. 2) If the card is 'online', the driver initiates card shutdown by setting the card state to suspending. This notifies the MIC daemon which invokes shutdown and sets card state to 'suspended'. The driver returns after the shutdown is complete. 3) If the card is already being shutdown, possibly by a host user space application, the driver sets the card state to 'suspended' and returns after the shutdown is complete. During the PM_POST_SUSPEND phase, the driver simply notifies the daemon and returns. The daemon boots those cards that were previously online during the suspend phase.
