In Linux or android systems, if we want to configure the gpio pin of the feisikar imx6 processor, for example, the gpio_19 pin, we should look like this: #define MX6Q_PAD_GPIO_19__GPIO_4_5\(_MX6Q_PAD_GPIO_19__GPIO_4_5 | MUX_PAD_CTRL(NO_PAD_CTRL)) _ Mx6q_pad_gpio_1920.gpio_4_5 is defined: #define _MX6Q_PAD_GPIO_19__GPIO_4_5\IOMUX_PAD(0x0624, 0x0254, 5, 0x0000, 0, 0) The iomux_pad macro is a key macro defining gpio. Its prototype is: #define IOMUX_PAD(_pad_ctrl_ofs, _mux_ctrl_ofs, _mux_mode, _s

transparent to all user space applicationsAll power switching is done within the ASOC core. No code changes orRecompiling are required for user space applications. dapm makes powerSwitching decisions based upon any audio stream (capture/playback)Activity and Audio Mixer settings within the device. Dapm spans the whole machine. It covers power control within the entireAudio Subsystem, this includes des internal codec power blocks and MachineLevel Power Systems. There are 4 Power domains within d

one important concept in ASOC: Kcontrol, unfamiliar readers need to browse through my previous article: Linux ALSA sound card driver Four: control device creation. Typically, a kcontrol represents a mixer (mixer), or a MUX (multi-channel switch), or a volume controller, and so on. As we know from the above article, defining a kcontrol is primarily about defining a snd_kcontrol_new structure, which, for the sake of discussion, is again given its defin

integers rather than floating-point computations greatly reduces the hardware size and power consumption of TPU. A TPU clock contains 65,536 8-bit integer multipliers. A mainstream GPU used in a cloud environment, typically consisting of thousands of 32-bit floating-point multipliers. As long as the 8-bit to meet the accuracy requirements, can bring more than 25 times times the performance improvement. Risc,cisc and TPU instruction set Programmability is another important design goal for TPU. T

Through the source we know that toast is based on WindowManager to display, then we can completely masturbate a custom toast out, the source code is as follows:Import Android.content.context;import Android.graphics.pixelformat;import Android.os.handler;import Android.os.message;import Android.view.gr

existing CATV technology, including the WDM Technology, directly transmit analog signals without processing to the monitoring center for centralized monitoring. The disadvantage is that the network construction cost is very high and the WDM Technology must be passive in the middle of bare optical brazing ), in some applications, it is feasible in a small area, but the cost of centralized monitoring is high

Introduction One of the most frequently done tasks in Windows Driver Model (WDM) drivers is sending input/output request packets (IRPs) from one driver to another driver. A driver either creates its own IRP and sends it to a lower driver, or the driver forwards the IRPsThat it has es from another driver that is attached abve. This article discusses all the possible ways that a driver can send IRPs to a lower driver with annotated sample code. dependin

Solution: Do not use waveout and set the volume to the maximum value in the Windows volume control..Q is the quality of sound output between directsound and waveout different?A1 in win2kxp (or using a WDM driver), waveout and directsound are only transmitted in PThere are two d

One or more Io queues. 4. A callback routine for multiple active Io events is similar to the dispatchxxx of WDM. 5. plug-and-play and power management callback routines are supported. 6. Supported WMI callback routine

hardware interruptions, their drivers have an interruption service routine (ISR) and a delay process call (DPC) routine. Drivers generally have several dispatch functions that support different types of IRPs. Three of them are required. Therefore, a task of the WDM driver developer is to select the required routine for this container. Figure 21 1-5Content in the WDM driver "Container" 7. The

Particle physics involves the "standard model" of the universe, as does WDM. Figure 5-5 shows the ownership process of a typical IRP in each processing phase. Not every type of IRP goes through these steps, because some steps of the device type and IRP type change or do not exist at all. Although there may be various forms of change in this process, this figure provides a good starting point for our discussion. More complicated than you think... When
