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

dm: core: Allow finding a uclass device by partial name

2022-04-25T14:00:03Z

In some cases two devices are related and the only way to tell is to check that the names partially patch. Add a way to check this without needing to create a new string for the comparison. Fix the comment for device_find_child_by_namelen() while we are here. Signed-off-by: Simon Glass

dm: core: Rename and fix uclass_get_by_name_len()

2022-04-25T14:00:03Z

It seems that namelen is more common in U-Boot. Rename this function to fit in better. Also fix a bug where it breaks the operation of uclass_get_by_name() and add a test. Signed-off-by: Simon Glass Reported-by: Patrick Delaunay Reported-by: Tim Harvey

doc: replace @return by Return:

2022-01-19T17:11:34Z

Sphinx expects Return: and not @return to indicate a return value. find . -name '*.c' -exec \ sed -i 's/^\(\s\)\*\(\s*\)@return\(\s\)/\1*\2Return:\3/' {} \; find . -name '*.h' -exec \ sed -i 's/^\(\s\)\*\(\s*\)@return\(\s\)/\1*\2Return:\3/' {} \; Signed-off-by: Heinrich Schuchardt

dm: core: Allow getting some basic stats

2021-12-23T15:24:40Z

Add a function that returns some basic stats about driver model. For now we only have two. Signed-off-by: Simon Glass

dm: core: Don't allow uclass use before ready

2021-08-08T17:27:27Z

At present it is possible to call uclass_get() before driver model is inited. In fact this happens on x86 boards which use Intel FSPv1, since mrccache_get_region() tries to get the SPI flash device very early during init. This has always been undefined behaviour. Previously it generally worked, i.e. returned an error code without crashing, because gd->uclass_root_s is zeroed and the uclass can be added despite driver model not being ready, due to the way lists are implemented. With the change to use a gd->uclass_root pointer, this no-longer works. For example, it causes a hang on minnowmax. Fix this by adding a check that driver model is ready when uclass_get() is called. This function is called in the process of locating any device, so it is a good place to add the check. This fixes booting on minnowmax.

test: Add DM_DMA to be disabled

2021-07-21T16:27:34Z

At present if DM_DMA is disabled on a sandbox build, the build fails. Make the test conditional. Signed-off-by: Simon Glass

test: Drop struct dm_test_state

2021-03-12T14:57:30Z

Driver model is a core part of U-Boot. We don't really need to have a separate test structure for the driver model tests and it makes it harder to write a test if you have to think about which type of test it is. Subsume the fields from struct dm_test_state into struct unit_test_state and delete the former. Signed-off-by: Simon Glass
