In case MMU is enabled, we must take MMU page size into consideration when reporting dram size to the user. This is because the MMU page size can be a value which is NOT a power-of-2 value. As a result, the total DRAM size (which is always a power-of-2 value) needed to be rounded-down. Signed-off-by:

DRAM physical page sizes depend of the amount of HBMs available in the device. this number is device-dependent and may also be subject to binning when one or more of the DRAM controllers are found to to be faulty. Such a configuration may lead to partitioning the DRAM to non-power-of-2 pages. To support this feature we also need to add infrastructure of address scarmbling. Signed-off-by:

Accessing kernel allocated memory through debugfs should not be allowed as it introduces a security vulnerability. We remove the option to read/write kernel memory for all asics. Signed-off-by:

When working with DRAM MMU, we should supply the userspace with the virtual start address of the DRAM instead of the physical one. This is because the physical one has no meaning for the user as he only knows the virtual address range. Signed-off-by:

Often WARN is defined in data-centers as BUG and we would like to avoid hanging the entire server on some internal error of the driver (important as it might be). Therefore, use dev_crit instead. Signed-off-by:

There is no reason to keep PM_API_MAX around. The commit acfdd185 ("firmware: xilinx: Use hash-table for api feature check") removed its usage that's why it is not used anywhere now. Signed-off-by:

When create the VMCI queue pair tracking data structures on the host side, the IOCTL for creating the VMCI queue pair didn't validate the queue pair size parameters. This change adds checks for this. This avoids a memory allocation issue in qp_host_alloc_queue, as reported by nslusarek@gmx.net. The check in qp_host_alloc_queue has also been updated to enforce the maximum queue pair size as defined by VMCI_MAX_GUEST_QP_MEMORY. The fix has been verified using sample code supplied by nslusarek@gmx.net. Reported-by: nslusarek@gmx.net Reviewed-by:

When the VMCI host support releases guest memory in the case where the VM was killed, the pinned guest pages aren't locked. Use set_page_dirty_lock() instead of set_page_dirty(). Testing done: Killed VM while having an active VMCI based vSocket connection and observed warning from ext4. With this fix, no warning was observed. Ran various vSocket tests without issues. Fixes: 06164d2b ("VMCI: queue pairs implementation.") Reviewed-by:

VMCI queue pair allocation is disabled, if a VM is in FT mode. In these cases, VMware Tools may still once in a while attempt to create a vSocket stream connection, resulting in multiple warnings in the kernel logs. Therefore downgrade the error log to a debug log. Reviewed-by:
