test: lmb: Rework lib_test_lmb_max_regions test to scale

2023-02-08T19:09:39+00:00

First, this test depends on CONFIG_LMB_USE_MAX_REGIONS, so add that as a
test before building. Second, instead of using a hard-coded value of 8,
which is the default of CONFIG_LMB_USE_MAX_REGIONS previously, use that
directly and update the comments. The only trick here is that one part
of the test itself also was written with the value of 8 itself in mind.
Rework the size of the lmb region we allocate to scale with the value of
CONFIG_LMB_USE_MAX_REGIONS.

display_options: print_size: Fix order overflow

2022-09-23T19:13:18+00:00

Function print_size() round size to the nearst value with one decimal
fraction number. But in special cases also unit order may overflow.

For example value 1073689396 is printed as "1024 MiB" and value 1073741824
as "1 GiB".

Fix this issue by detecting order overflow and increasing unit order.
With this change also value 1073689396 is printed as "1 GiB".

test: Add some tests for kconfig.h

2022-08-10T17:38:30+00:00

The macros in this file are a little confusing and we currently have no
tests to check that they work as expected.

Add some tests which check the macros in C code. Add a few tests which
check that the build errors are generated correctly too, using buildman's
-a option.

abuf: Correct a corner case with abuf_realloc()

2022-04-06T18:01:42+00:00

If the buffer is empty and not allocated, then abuf_realloc() tries to
copy invalid data. This happens because an incorrect change to use
memdup() was added after the original code was written.

lmb: remove lmb_is_nomap() from include

2021-11-20T09:53:00+00:00

Defining static functions in includes should be avoided.
Function lmb_is_nomap() is only used in the unit test.
So move it to the unit test.

Add support for an owned buffer

2021-10-08T19:53:26+00:00

When passing a data buffer back from a function, it is not always clear
who owns the buffer, i.e. who is responsible for freeing the memory used.
An example of this is where multiple files are decompressed from the
firmware image, using a temporary buffer for reading (since the
compressed data has to live somewhere) and producing a temporary or
permanent buffer with the resuilts.

Where the firmware image can be memory-mapped, as on x86, the compressed
data does not need to be buffered, but the complexity of having a buffer
which is either allocated or not, makes the code hard to understand.

Introduce a new 'abuf' which supports simple buffer operations:

- encapsulating a buffer and its size
- either allocated with malloc() or not
- able to be reliably freed if necessary
- able to be converted to an allocated buffer if needed

This simple API makes it easier to deal with allocated and memory-mapped
buffers.

lib: wrap crypt API to hide errno usage

2021-07-23T17:36:20+00:00

In order to prevent using the global errno, replace it with a static
version and create a wrapper function which returns the error value.
