Subject: [RFC RFT PATCH v4 4/4] gpiolib: Implement fast processing path in get/set array
Date: Tue, 21 Aug 2018 01:43:41 +0200 [thread overview]
Message-ID: <20180820234341.5271-5-jmkrzyszt@gmail.com> (raw)
In-Reply-To: <20180820234341.5271-1-jmkrzyszt@gmail.com>
Certain GPIO descriptor arrays returned by gpio_get_array() may contain
information on direct mapping of array members to pins of a single GPIO
chip in hardware order. In such cases, bitmaps of values can be passed
directly from/to the chip's .get/set_multiple() callbacks without
wasting time on iterations.
Add respective code to gpiod_get/set_array_bitmap_complex() functions.
Pins not applicable for fast path are processed as before, skipping
over the 'fast' ones.

+Arrays of pins
+--------------
+In addition to requesting pins belonging to a function one by one, a device may
+also request an array of pins assigned to the function. The way those pins are
+mapped to the device determines if the array qualifies for fast bitmap
+processing. If yes, a bitmap is passed over get/set array functions directly
+between a caller and a respective .get/set_multiple() callback of a GPIO chip.
+
+In order to qualify for fast bitmap processing, the pin mapping must meet the
+following requirements:
+- it must belong to the same chip as other 'fast' pins of the function,
+- its index within the function must match its hardware number within the chip.
+
+Open drain and open source pins are excluded from fast bitmap output processing.

Note that for optimal performance GPIOs belonging to the same chip should be
contiguous within the array of descriptors.
+Still better performance may be achieved if array indexes of the descriptors
+match hardware pin numbers of a single chip. If an array passed to a get/set
+array function matches the one obtained from gpiod_get_array() and array_info
+associated with the array is also passed, the function may take a fast bitmap
+processing path, passing the value_bitmap argument directly to the respective
+.get/set_multiple() callback of the chip. That allows for utilization of GPIO
+banks as data I/O ports without much loss of performance.

The return value of gpiod_get_array_value() and its variants is 0 on success
or negative on error. Note the difference to gpiod_get_value(), which returns
0 or 1 on success to convey the GPIO value. With the array functions, the GPIO
