Antoine Ténart authored
When using a group only pinctrl driver, which does not have any information on the pins it is useless to define a get_group_pins always returning an empty list of pins. When not using get_group_pin[1], a driver must implement it so pins = NULL and num_pins = 0. This patch makes it the default behaviour if not defined in the pinctrl driver when used in pinmux enable and disable funtions and in pinctrl_groups_show. It also adds a check in pinctrl_get_group_pins and return -EINVAL if not defined. This function is called in the gpiolib when adding when pingroup range. It cannot be used if no group is defined, so this seams reasonable. [1] get_group_pin(struct pinctrl_dev *pctldev, unsigned selector, const unsigned **pins, unsigned *num_pins); Signed-off-by: Antoine TÃ

This lets the gpiolib core handle the irqchip set-up and chained IRQ on the primary (behind the mux) IRQ chip in the st pinctrl driver. Default irq type is set to level low at irqchip add time. The v1 was sent by Linus (https://lkml.org/lkml/2014/4/4/287). Two changes were necessary to make it to work properly on STiH416: 1 - dev reference was not passed to the gpio_chip struct, causing a panic. 2 - gpiochip_irqchip_add passed IRQ_TYPE_NONE as default type, which caused lot of warnings at init time. I choose IRQ_TYPE_LEVEL_LOW as default.

In the current version, when using perf record, if something goes wrong in tools/perf/builtin-record.c:375 session = perf_session__new(file, false, NULL); The error message: "Not enough memory for reading per file header" is issued. This error message seems to be outdated and is not very helpful. This patch proposes to replace this error message by "Perf session creation failed" I believe this issue has been brought to lkml: https://lkml.org/lkml/2014/2/24/458 although this patch only tackles a (small) part of the issue. Additionnaly, this patch improves error reporting in tools/perf/util/data.c open_file_write. Currently, if the call to open fails, the user is unaware of it. This patch logs the error, before returning the error code to the caller.

Every event in the perf-kvm has a 'stats' structure, which contains max/min/average/etc times of handling this event. The problem is that the 'perf-kvm stat report' command always shows that 'min time' is 0us for every event. Example: # perf kvm stat report Analyze events for all VCPUs: VM-EXIT Samples Samples% Time% Min Time Max Time Avg time [..] 0xB2 MSCH 12 0.07% 0.00% 0us 8us 7.31us ( +- 2.11% ) 0xB2 CHSC 12 0.07% 0.00% 0us 18us 9.39us ( +- 9.49% ) 0xB2 STPX 8 0.05% 0.00% 0us 2us 1.88us ( +- 7.18% ) 0xB2 STSI 7 0.04% 0.00% 0us 44us 16.49us ( +- 38.20% ) [..] This happens because the 'stats' structure is not initialized and stats->min equals to 0. Lets initialize the structure for every event after its allocation using init_stats() function. This initializes stats->min to -1 and makes 'Min time' statistics counting work: # perf kvm stat report Analyze events for all VCPUs: VM-EXIT Samples Samples% Time% Min Time Max Time Avg time [..] 0xB2 MSCH 12 0.07% 0.00% 6us 8us 7.31us ( +- 2.11% ) 0xB2 CHSC 12 0.07% 0.00% 7us 18us 9.39us ( +- 9.49% ) 0xB2 STPX 8 0.05% 0.00% 1us 2us 1.88us ( +- 7.18% ) 0xB2 STSI 7 0.04% 0.00% 1us 44us 16.49us ( +- 38.20% ) [..] Signed-off-by: Alexander Yarygin <yarygin@linux.vnet.ibm.com> Signed-off-by: Christian Borntraeger <borntraeger@de.ibm.com> Reviewed-by: David Ahern <dsahern@gmail.com> Link: http://lkml.kernel.org/r/1397053319-2130-3-git-send-email-borntraeger@de.ibm.com [ Fixing the perf examples changelog output ] Signed-off-by: Jiri Olsa <jolsa@redhat.com>
