soc: Switch back to struct platform_driver::remove()

2024-11-01T16:08:57+00:00

After commit 0edb555a65d1 ("platform: Make platform_driver::remove() return void") .remove() is (again) the right callback to implement for platform drivers. Convert all platform drivers below drivers/soc to use .remove(), with the eventual goal to drop struct platform_driver::remove_new(). As .remove() and .remove_new() have the same prototypes, conversion is done by just changing the structure member name in the driver initializer. On the way do a few whitespace changes to make indention consistent.

If we fail to allocate memory for cb_data by kmalloc, the memory allocation for eve_data is never freed, add the missing kfree() in the error handling path.

2024-06-03T11:07:56+00:00

Add support to register subsystem restart events from firmware for Versal and Versal NET platforms. This event is received when firmware requests for subsystem restart. After receiving this event, the kernel needs to be restarted.

soc: xilinx: rename cpu_number1 to dummy_cpu_number

2024-06-03T11:07:56+00:00

The per cpu variable cpu_number1 is passed to xlnx_event_handler as argument "dev_id", but it is not used in this function. So drop the initialization of this variable and rename it to dummy_cpu_number. This patch is to fix the following call trace when the kernel option CONFIG_DEBUG_ATOMIC_SLEEP is enabled: BUG: sleeping function called from invalid context at include/linux/sched/mm.h:274 in_atomic(): 1, irqs_disabled(): 0, non_block: 0, pid: 1, name: swapper/0 preempt_count: 1, expected: 0 CPU: 0 PID: 1 Comm: swapper/0 Not tainted 6.1.0 #53 Hardware name: Xilinx Versal vmk180 Eval board rev1.1 (QSPI) (DT) Call trace: dump_backtrace+0xd0/0xe0 show_stack+0x18/0x40 dump_stack_lvl+0x7c/0xa0 dump_stack+0x18/0x34 __might_resched+0x10c/0x140 __might_sleep+0x4c/0xa0 __kmem_cache_alloc_node+0xf4/0x168 kmalloc_trace+0x28/0x38 __request_percpu_irq+0x74/0x138 xlnx_event_manager_probe+0xf8/0x298 platform_probe+0x68/0xd8 Fixes: daed80ed0758 ("soc: xilinx: Fix for call trace due to the usage of smp_processor_id()") Signed-off-by: Jay Buddhabhatti Link: https://lore.kernel.org/r/20240408110610.15676-1-jay.buddhabhatti@amd.com Signed-off-by: Michal Simek

drivers: soc: xilinx: add check for platform

2024-01-04T16:02:49+00:00

Some error event IDs for Versal and Versal NET are different. Both the platforms should access their respective error event IDs so use sub_family_code to check for platform and check error IDs for respective platforms. The family code is passed via platform data to avoid platform detection again. Platform data is setup when even driver is registered.
