docs: fix references to docs/devel/tracing.rst Commit e50caf4a5c ("tracing: convert documentation to rST") converted docs/devel/tracing.txt to docs/devel/tracing.rst. We still have several references to the old file, so let's fix them with the following command: sed -i s/tracing.txt/tracing.rst/ $(git grep -l docs/devel/tracing.txt) Signed-off-by: Stefano Garzarella <sgarzare@redhat.com> Reviewed-by: Philippe Mathieu-Daudé <philmd@redhat.com> Message-Id: <20210517151702.109066-2-sgarzare@redhat.com> Signed-off-by: Thomas Huth <thuth@redhat.com>

hw/gpio/nrf51_gpio: Add nRF51 GPIO peripheral This adds a model of the nRF51 GPIO peripheral. Reference Manual: http://infocenter.nordicsemi.com/pdf/nRF51_RM_v3.0.pdf The nRF51 series microcontrollers support up to 32 GPIO pins in various configurations. The pins can be used as input pins with pull-ups or pull-down. Furthermore, three different output driver modes per level are available (disconnected, standard, high-current). The GPIO-Peripheral has a mechanism for detecting level changes which is not featured in this model.

hw/gpio: Add GPIO model for Nuvoton NPCM7xx The NPCM7xx chips have multiple GPIO controllers that are mostly identical except for some minor differences like the reset values of some registers. Each controller controls up to 32 pins. Each individual pin is modeled as a pair of unnamed GPIOs -- one for emitting the actual pin state, and one for driving the pin externally. Like the nRF51 GPIO controller, a gpio level may be negative, which means the pin is not driven, or floating.

trace-events: Shorten file names in comments We spell out sub/dir/ in sub/dir/trace-events' comments pointing to source files. That's because when trace-events got split up, the comments were moved verbatim. Delete the sub/dir/ part from these comments. Gets rid of several misspellings.

trace: enforce that every trace-events file has a final newline When generating the trace-events-all file, the build system simply concatenates all the individual trace-events files. If any one of those files does not have a final newline, the printf format string will have the contents of the first line of the next file appended to it, which is usually a '#' comment.

# pl061.c
hw/gpio/pl061: Honour Luminary PL061 PUR and PDR registers The Luminary variant of the PL061 has registers GPIOPUR and GPIOPDR which lets the guest configure whether the GPIO lines are pull-up, pull-down, or truly floating. Instead of assuming all lines are pulled high, honour the PUR and PDR registers. For the plain PL061, continue to assume that lines have an external pull-up resistor, as we did before. The stellaris board actually relies on this behaviour -- the CD line of the ssd0323 display device is connected to GPIO output C7, and it is only because of a different bug which we're about to fix that we weren't incorrectly driving this line high on reset and putting the ssd0323 into data mode.

hw/gpio/pl061: Convert to 3-phase reset and assert GPIO lines correctly on reset The PL061 comes out of reset with all its lines configured as input, which means they might need to be pulled to 0 or 1 depending on the 'pullups' and 'pulldowns' properties. Currently we do not assert these lines on reset; they will only be set whenever the guest first touches a register that triggers a call to pl061_update(). Convert the device to three-phase reset so we have a place where we can safely call qemu_set_irq() to set the floating lines to their correct values.
