misc: pvpanic: add crash loaded event

2020-01-14T14:07:37Z

Some users prefer kdump tools to generate guest kernel dumpfile, at the same time, need a out-of-band kernel panic event. Currently if booting guest kernel with 'crash_kexec_post_notifiers', QEMU will receive PVPANIC_PANICKED event and stop VM. If booting guest kernel without 'crash_kexec_post_notifiers', guest will not call notifier chain. Add PVPANIC_CRASH_LOADED bit for pvpanic event, it means that guest kernel actually hit a kernel panic, but the guest kernel wants to handle by itself.

misc: pvpanic: move bit definition to uapi header file

2020-01-14T14:07:37Z

Some processes outside of the kernel(Ex, QEMU) should know what the value really is for, so move the bit definition to a uapi file. Suggested-by: Greg KH Signed-off-by: zhenwei pi Link: https://lore.kernel.org/r/20200102023513.318836-2-pizhenwei@bytedance.com Signed-off-by: Greg Kroah-Hartman

habanalabs: expose reset counters via existing INFO IOCTL

2019-11-21T09:35:47Z

Expose both soft and hard reset counts via INFO IOCTL. This will allow system management applications to easily check if the device has undergone reset. Signed-off-by: Moti Haimovski Reviewed-by: Oded Gabbay Signed-off-by: Oded Gabbay

habanalabs: export uapi defines to user-space

2019-11-21T09:35:46Z

The two defines that control the maximum size of a command buffer and the maximum number of JOBS per CS need to be exported to the user as they are part of the API towards user-space. Signed-off-by: Oded Gabbay Reviewed-by: Omer Shpigelman

habanalabs: expose card name in INFO IOCTL

2019-11-21T09:35:45Z

To enable userspace processes, e.g. management utilities, to display the card name to the user, add the card name property to the HW_IP structure that is copied to the user in the INFO IOCTL. Signed-off-by: Oded Gabbay

habanalabs: add opcode to INFO IOCTL to return clock rate

2019-11-21T09:35:45Z

Add a new opcode to the INFO IOCTL to allow the user application to retrieve the ASIC's current and maximum clock rate. The rate is returned in MHz. Signed-off-by: Oded Gabbay Reviewed-by: Tomer Tayar

misc: fastrpc: add mmap/unmap support

2019-10-10T13:28:10Z

Support the allocation/deallocation of buffers mapped to the DSP. When the memory mapped to the DSP at process creation is not enough, the fastrpc library can extend it at runtime. This avoids having to do large preallocations by default.

habanalabs: stop using the acronym KMD

2019-09-05T11:55:27Z

We want to stop using the acronym KMD. Therefore, replace all locations (except for register names we can't modify) where KMD is written to other terms such as "Linux kernel driver" or "Host kernel driver", etc. Signed-off-by: Oded Gabbay Reviewed-by: Omer Shpigelman

habanalabs: add uapi to retrieve aggregate H/W events

2019-09-05T11:55:27Z

Add a new opcode to INFO IOCTL to retrieve aggregate H/W events. i.e. the events counters are NOT cleared upon device reset, but count from the loading of the driver. Add the code to support it in the device event handling function. Signed-off-by: Oded Gabbay Reviewed-by: Omer Shpigelman
