devres: Fix memory leakage caused by driver API devm_free_percpu()

2024-07-04T10:34:50Z

It will cause memory leakage when use driver API devm_free_percpu() to free memory allocated by devm_alloc_percpu(), fixed by using devres_release() instead of devres_destroy() within devm_free_percpu().

devres: Fix devm_krealloc() wasting memory

2024-07-04T10:34:38Z

Driver API devm_krealloc() calls alloc_dr() with wrong argument @total_new_size, so causes more memory to be allocated than required fix this memory waste by using @new_size as the argument for alloc_dr().

drivers/base: use ARCH_DMA_MINALIGN instead of ARCH_KMALLOC_MINALIGN

2023-06-19T23:19:20Z

ARCH_DMA_MINALIGN represents the minimum (static) alignment for safe DMA operations while ARCH_KMALLOC_MINALIGN is the minimum kmalloc() objects alignment.

devres: Pass unique name of the resource to devm_add_action()

Pass the unique name of the resource to devm_add_action(), so it will be easier to debug managed resources. Signed-off-by: Andy Shevchenko Link: https://lore.kernel.org/r/20230224200745.17324-1-andriy.shevchenko@linux.intel.com Signed-off-by: Greg Kroah-Hartman

devres: Use kmalloc_size_roundup() to match ksize() usage

2022-11-09T14:11:46Z

Round up allocations with kmalloc_size_roundup() so that devres's use of ksize() is always accurate and no special handling of the memory is needed by KASAN, UBSAN_BOUNDS, nor FORTIFY_SOURCE.

devres: Slightly optimize alloc_dr()

2022-09-01T16:17:14Z

If the gfp flag used for the memory allocation already has __GFP_ZERO, then there is no need to explicitly clear the "struct devres_node". It is already zeroed. This saves a few cycles when using devm_zalloc() and co. In the case of devres_alloc() (which calls __devres_alloc_node()), the compiler could remove the test and the memset() because it should be able to see that the __GFP_ZERO flag is set. So this would make the code both faster and smaller.

devres: Enable trace events

2021-06-15T15:14:36Z

In some cases the printf() mechanism is too heavy and can't be used. For example, when debugging a race condition involving devres API. When CONFIG_DEBUG_DEVRES is enabled I can't reproduce an issue, and otherwise it's quite visible with a useful information being collected. Enable trace events for devres part of the driver core.
