Changes in v6:
- Fix typo in for_each_set_clump8 macro definition ('offset' should be
'start')
- Fix data type mismatch for format specifier of warning print
statements in __check_eq_clump8
- Fix typo in symbol suffix for definition of __check_eq_clump8
- Fix typo in parameter passed to expect_eq_clump8 (missing '&' for
clump argument)
While adding GPIO get_multiple/set_multiple callback support for various
drivers, I noticed a pattern of looping manifesting that would be useful
standardized as a macro.
This patchset introduces the for_each_set_clump8 macro and utilizes it
in several GPIO drivers. The for_each_set_clump macro8 facilitates a
for-loop syntax that iterates over a memory region entire groups of set
bits at a time.
For example, suppose you would like to iterate over a 32-bit integer 8
bits at a time, skipping over 8-bit groups with no set bit, where
XXXXXXXX represents the current 8-bit group:
Example: 10111110 00000000 11111111 00110011
First loop: 10111110 00000000 11111111 XXXXXXXX
Second loop: 10111110 00000000 XXXXXXXX 00110011
Third loop: XXXXXXXX 00000000 11111111 00110011
Each iteration of the loop returns the next 8-bit group that has at
least one set bit.
The for_each_set_clump8 macro has four parameters:
* start: set to the bit offset of the current clump
* clump: set to the current clump value
* bits: bitmap to search within
* size: bitmap size in number of bits
In this version of the patchset, the for_each_set_clump macro has been
reimplemented and simplified based on the suggestions provided by Rasmus
Villemoes and Andy Shevchenko in the version 4 submission.
In particular, the function of the for_each_set_clump macro has been
restricted to handle only 8-bit clumps; the drivers that use the
for_each_set_clump macro only handle 8-bit ports so a generic
for_each_set_clump implementation is not necessary. Thus, a solution for
odd-sized clumps (e.g. 3-bit, 7-bit, etc.) mismatching word boundaries
can be postponed until a driver appears that actually requires a generic
for_each_set_clump implementation.
In addition, the bitmap_get_value8 and bitmap_set_value8 functions are
introduced to get and set 8-bit values respectively. Their use is based
on the behavior suggested in the patchset version 4 review. Similarly,
the implementation of the find_next_clump function has been simplified
in order for the function to match the syntax and use of the
find_next_bit function.

2.20.1
This macro iterates for each 8-bit group of bits (clump) with set bits,
within a bitmap memory region. For each iteration, "start" is set to the
bit offset of the found clump, while the respective clump value is
stored to the location pointed by "clump". Additionally, the
bitmap_get_value8 and bitmap_set_value8 functions are introduced to
respectively get and set an 8-bit value in a bitmap memory region.

The introduction of the for_each_set_clump8 macro warrants test cases to
verify the implementation. This patch adds test case checks for whether
an out-of-bounds clump index is returned, a zero clump is returned, or
the returned clump value differs from the expected clump value.

errh, why pass the value by reference? That seems rather odd. Also, if
anybody passes a value that doesn't fit in 8 bits, they get what they
deserve; IOW I don't see a reason for the masking in the last line, but
if its convenient for the users, keep it. In any case, please change the
type of value.

I am still waiting for feedback from the core lib maintainers on this patch.
If I just get an ACK I can apply it to the GPIO tree, if noone else cares
I might just go in and apply it, but it feels slightly outside of my
jurisdiction.
Maybe people were just a bit stressed out around christmas?
What about looking at it now?
Yours,
Linus Walleij
