sculpt: introduce runtime priorities This patch adds 4 priority levels to the runtime subsystem. The highest priority is used for components that are critical for the operation of Sculpt, in particular the Leitzentrale GUI. All regularly deployed components are assigned the lowest priority by default. With priorities available in the runtime subsystem, this patch flattens the priority levels at the top-level init to only two levels and overlays the priority bands of the drivers, leitzentrale, and runtime subsystems into one priority band. This has three benenfits: - This change prevents the starvation of the Leitzentrale GUI from a spinning high-priority driver (issue #3997). - The change will also ease the hosting of latency-critical components in the runtime subsystem that are prioritized higher than regular components, the storage stack, and the network stack. - The Leitzentrale GUI remains always perfectly responsive regardless of the workloads deployed from packages. In the previous version, the runtime graph was sometimes stuttering on high system load. Issue #4045

gems: driver-manager subsystem for PC platforms This is a drivers subsystem that starts the most fundamental (framebuffer, input, block) device drivers dynamically, depending on the runtime-detected devices. The discovered block devices are reported as a "block_devices" report.

Turn framebuffer drivers into capture clients This patch replaces the use of the "Framebuffer" session interface by the new "Capture" session interface in all framebuffer drivers. Thanks to this change, those drivers have become mere clients of the nitpicker GUI server now, and are no longer critical for the liveliness of the GUI server. The patch touches the following areas: - The actual driver components. The new versions of all drivers have been tested on the respective hardware. Generally, the drivers have become simpler. - The drivers_interactive packages for various boards. The drivers subsystem no longer provides a "Framebuffer" service but needs a valid route to the "Capture" service provided by nitpicker. - The driver manager of Sculpt OS. - This patch changes the role of the test-framebuffer component from a framebuffer client to a capture server so that drivers (capture clients) can be directly connected to the test component without the nitpicker server. - Framebuffer driver no longer support the unbuffered mode. - The fb_bench.run script is no longer very meaningful because it interplays solely with nitpicker, not with the driver directly. - All run scripts for graphical scenarios and the related depot archives got adapted to the change. Fixes #3813

Replace input filter with event filter This commit applies the transition from the "Input" session to the "Event" session to the event-filtering mechansim. The functionality of the input_filter is now provided by the event_filter. The event filter requests only one "Event" session as destination for the filter result, which is usually routed to the nitpicker GUI server. It provides an "Event" service to which any number of event sources can connect. The configuration of the filter chain remains almost the same. Only the declaration of the <input> nodes is no longer needed. Instead, the configuration must specify <policy> nodes, which define the mapping of "Event" clients (event sources) to the inputs used in the filter chain. The patch adjusts all uses of the nitpicker GUI server accordingly such that the event filter reports events to nitpicker's event service instead of having nitpicker request an "Input" session. This dissolves the dependency of nitpicker from input drivers. Issue #3827

drivers_managed-pc: simplification This patch removes the former use of ram_fs, fs_rom, and fs_report from the subsystem and uses a report_rom instead. The fs-based reporting was introduced to accommodate automatically instantiated usb_block drivers, which turned out to be impractical for the sculpt scenario.

sculpt: introduce runtime priorities This patch adds 4 priority levels to the runtime subsystem. The highest priority is used for components that are critical for the operation of Sculpt, in particular the Leitzentrale GUI. All regularly deployed components are assigned the lowest priority by default. With priorities available in the runtime subsystem, this patch flattens the priority levels at the top-level init to only two levels and overlays the priority bands of the drivers, leitzentrale, and runtime subsystems into one priority band. This has three benenfits: - This change prevents the starvation of the Leitzentrale GUI from a spinning high-priority driver (issue #3997). - The change will also ease the hosting of latency-critical components in the runtime subsystem that are prioritized higher than regular components, the storage stack, and the network stack. - The Leitzentrale GUI remains always perfectly responsive regardless of the workloads deployed from packages. In the previous version, the runtime graph was sometimes stuttering on high system load. Issue #4045

sculpt: system reset via PS/2 and ACPI This patch enables sculpt to utilize the CPU reset mechanism via the PS/2 controller as well as the information provided via the ACPI FADT information. Whenever the /config/system file is changed to <system state="reset"/>, both mechanisms are triggered. Supporting both mechanisms is useful because the PS/2-based reset does not work reliably on modern machines. The PS/2-based reset is useful in the case when the FADT reset information refers to the PS/2 command port. In this case, the platform driver is unable to access this port because it is already handed out to the PS/2 driver. In this case, the PS/2 driver kicks in. Issue #2726

Replace input filter with event filter This commit applies the transition from the "Input" session to the "Event" session to the event-filtering mechansim. The functionality of the input_filter is now provided by the event_filter. The event filter requests only one "Event" session as destination for the filter result, which is usually routed to the nitpicker GUI server. It provides an "Event" service to which any number of event sources can connect. The configuration of the filter chain remains almost the same. Only the declaration of the <input> nodes is no longer needed. Instead, the configuration must specify <policy> nodes, which define the mapping of "Event" clients (event sources) to the inputs used in the filter chain. The patch adjusts all uses of the nitpicker GUI server accordingly such that the event filter reports events to nitpicker's event service instead of having nitpicker request an "Input" session. This dissolves the dependency of nitpicker from input drivers. Issue #3827

Turn framebuffer drivers into capture clients This patch replaces the use of the "Framebuffer" session interface by the new "Capture" session interface in all framebuffer drivers. Thanks to this change, those drivers have become mere clients of the nitpicker GUI server now, and are no longer critical for the liveliness of the GUI server. The patch touches the following areas: - The actual driver components. The new versions of all drivers have been tested on the respective hardware. Generally, the drivers have become simpler. - The drivers_interactive packages for various boards. The drivers subsystem no longer provides a "Framebuffer" service but needs a valid route to the "Capture" service provided by nitpicker. - The driver manager of Sculpt OS. - This patch changes the role of the test-framebuffer component from a framebuffer client to a capture server so that drivers (capture clients) can be directly connected to the test component without the nitpicker server. - Framebuffer driver no longer support the unbuffered mode. - The fb_bench.run script is no longer very meaningful because it interplays solely with nitpicker, not with the driver directly. - All run scripts for graphical scenarios and the related depot archives got adapted to the change. Fixes #3813
