crypto: qat - Removes the x86 dependency on the QAT drivers

2022-06-24T09:12:29+00:00

This dependency looks outdated. After the previous patch, we have been able to use this driver to encrypt some data and to create working VF on arm64. We have not tested it yet on any big endian machine, hence the new dependency Signed-off-by: Yoan Picchi Signed-off-by: Herbert Xu

crypto: qat - replace get_current_node() with numa_node_id()

2022-06-24T09:12:29+00:00

Currently the QAT driver code uses a self-defined wrapper function called get_current_node() when it wants to learn the current NUMA node. This implementation references the topology_physical_package_id[] array, which more or less coincidentally contains the NUMA node id, at least on x86. Because this is not universal, and Linux offers a direct function to learn the NUMA node ID, replace that function with a call to numa_node_id(), which would work everywhere. This fixes the QAT driver operation on arm64 machines. Reported-by: Yoan Picchi Signed-off-by: Andre Przywara Signed-off-by: Yoan Picchi Signed-off-by: Herbert Xu

crypto: ccp - During shutdown, check SEV data pointer before using

2022-06-24T09:12:29+00:00

On shutdown, each CCP device instance performs shutdown processing. However, __sev_platform_shutdown_locked() uses the controlling psp structure to obtain the pointer to the sev_device structure. However, during driver initialization, it is possible that an error can be received from the firmware that results in the sev_data pointer being cleared from the controlling psp structure. The __sev_platform_shutdown_locked() function does not check for this situation and will segfault. While not common, this scenario should be accounted for. Add a check for a NULL sev_device structure before attempting to use it. Fixes: 5441a07a127f ("crypto: ccp - shutdown SEV firmware on kexec") Signed-off-by: Tom Lendacky Signed-off-by: Herbert Xu

crypto: ccp - Fix device IRQ counting by using platform_irq_count()

2022-06-24T09:09:01+00:00

The ccp driver loops through the platform device resources array to get the IRQ count for the device. With commit a1a2b7125e10 ("of/platform: Drop static setup of IRQ resource from DT core"), the IRQ resources are no longer stored in the platform device resource array. As a result, the IRQ count is now always zero. This causes the driver to issue a second call to platform_get_irq(), which fails if the IRQ count is really 1, causing the loading of the driver to fail. Replace looping through the resources array to count the number of IRQs with a call to platform_irq_count().

crypto: hisilicon/qm - modify event irq processing

2022-06-17T09:19:20+00:00

When the driver receives an event interrupt, the driver will enable the event interrupt after handling all completed tasks on the function, tasks on the function are parsed through only one thread. If the task's user callback takes time, other tasks on the function will be blocked. Therefore, the event irq processing is modified as follows: 1. Obtain the ID of the queue that completes the task. 2. Enable event interrupt. 3. Parse the completed tasks in the queue and call the user callback. Enabling event interrupt in advance can quickly report pending event interrupts and process tasks in multiple threads. Signed-off-by: Weili Qian Signed-off-by: Herbert Xu

crypto: hisilicon/qm - move alloc qm->wq to qm.c

2022-06-17T09:19:20+00:00

Before stopping the function, the driver needs to flush all the remaining work about event irq. Therefore, accelerator drivers use a private workqueue(qm->wq) to handle event irq instead of the system workqueue. This patch moves alloc workqueue from sec_main.c and zip_main.c to qm.c.
