dm: fix mis-word in SPL_DM description

2022-07-26T08:30:56Z

Replace logically correct word in the description. Fixes: 91a91ff804d ("dm: Add Kconfig options for driver model SPL support") Signed-off-by: Oleksandr Suvorov Reviewed-by: Simon Glass

dm: fix logic of lists_bind_fdt()

2022-07-26T08:30:56Z

If parameter drv of lists_bind_fdt() is specified, we shall bind only to this very driver and to no other. If the driver drv has an of_match property, we shall only bind to the driver if it matches the compatible string of the device. Signed-off-by: Heinrich Schuchardt Reviewed-by: Simon Glass

dm: avoid NULL dereference in lists_bind_fdt()

2022-07-26T08:30:56Z

If parameter drv of lists_bind_fdt() is specified, we want to bind to this specific driver even if its field of_match is NULL. If entry->of_match is NULL, we should not dereference it in a debug statement.

dm: avoid NULL dereference in add_item()

2022-07-26T08:30:56Z

acpi_add_other_item() passes dev = NULL. Instead of dev->name write the string "other" to the debug log: ACPI: Writing ACPI tables at 1fd3000 0base: writing table '' * other: Added type 3, 0000000011fd4000, size 240 1facs: writing table 'FACS' * other: Added type 3, 0000000011fd4240, size 40 5csrt: writing table 'CSRT' * other: Added type 3, 0000000011fd4280, size 30 Signed-off-by: Heinrich Schuchardt Reviewed-by: Simon Glass

tpl: Ensure all TPL symbols in Kconfig have some TPL dependency

2022-06-28T21:03:31Z

Tighten up symbol dependencies in a number of places. Ensure that a TPL specific option has at least a direct dependency on TPL. In places where it's clear that we depend on something more specific, use that dependency instead. Reported-by: Pali Rohár Signed-off-by: Tom Rini

dm: spl: Allow SPL to show memory usage

2022-06-28T02:09:52Z

Add an option to tell SPL to show memory usage for driver model just before it boots into the next phase. Signed-off-by: Simon Glass

dm: core: Add a command to show driver model statistics

2022-06-28T02:09:52Z

This command shows the memory used by driver model along with various hints as to what it might be if some 'core' tags were moved to use the tag list instead of a core (i.e. always-there) pointer. This may help with future work to reduce memory usage. Signed-off-by: Simon Glass

dm: core: Add a way to collect memory usage

2022-06-28T02:09:52Z

Add a function for collecting the amount of memory used by driver model, including devices, uclasses and attached data and tags. This information can provide insights into how to reduce the memory required by driver model. Future work may look at execution speed also. Signed-off-by: Simon Glass

dm: core: Support accessing core tags

2022-06-28T02:09:52Z

At present tag numbers are only allocated for non-core data, meaning that the 'core' data, like priv and plat, are accessed through dedicated functions. For debugging and consistency it is convenient to use tags for this 'core' data too. Add support for this, with new tag numbers and functions to access the pointer and size for each. Update one of the test drivers so that the uclass-private data can be tested here. There is some code duplication with functions like device_alloc_priv() but this is not addressed for now. At some point, some rationalisation may help to reduce code size, but more thought it needed on that. Signed-off-by: Simon Glass
