Request OS signal when DCI data is receivedĪn external DIAG receiver (e.g. Get statistics about missed/succeeded logs and events, issues DIAG_IOCTL_DCI_HEALTH_STATS to /dev/diag Specify array of requested log codes, writes to /dev/diag
Set up event streaming to the client, writes to /dev/diag Register call-backs for events and logs, writes to /dev/diag Get list of peripherals supported, issues DIAG_IOCTL_DCI_SUPPORT to /dev/diag Register a DCI client, issues DIAG_IOCTL_DCI_REG to /dev/diag You can register to certain events/masks and then receive the related information in call-backs. This seems to be about implementing a program that consumes Diag events. On the EC25, it seems only the following Linux programs use the avove API to generate logs via Diag: Shorten the length of a previously allocated bufferįree a buffer previously allocated with log_alloc()Ĭonvenience wrapper around log_alloc()/memcpy()/log_commit() This is about sending log messages via the Diag interface. Registering with Diag which gives the client a handle to the Diag. There is /usr/lib/libdiag.so.1 which is linked by virtually any Qualcomm or Quectel proprietary program running on the Linux in the Modem.ĭiag_peripheral_buffering_drain_immediateĭiag_configure_peripheral_buffering_tx_mode The Log code identifies the source/category of the logged information. Luckily the library is not performing much required functionality, so third-party programs like SnoopSnitch have managed to talk directly to the /dev/diag kernel device without needing to use that non-free library. In userspace on the Linux inside the modem, there is a (unfortunately again non-free) library called libdiag which offers some convenience API for programs to either consume DIAG or to generate/respond to DIAG received from the host/PC.
The Qualcomm Android Linux kernel (usd even on the non-Android devices) implements several related kernel drivers, see Qualcomm_Kernel Furthermore, code in the Linux processor might also want to offer some DIAG information towards the external host/PC. First of all, not only the external host/PC might want to consume DIAG information, but also code on the Linux processor inside the chip. In a multi-processor situation (like the MDM9215/MDM9x07 with their Linux-running Cortex-A5), the situation becomes slightly more complex. In a single-processor Modem (with only a baseband processor) it is rather simple: Some software on the baseband processor implements the DIAG protocol, and responds to any related requests received on the DIAG port.
Later, this became a virtual serial port over USB. Initially, this transport was a dedicated serial port/UART.
The general idea is that there is some physical transport medium between the chipset/modem and an external PC, and the PC can request certain diagnostic information to be sent via that physical transport. It is not publicly documented, but there are tools from Qualcomm (QPST, QXDM) as well as proprietary third-party tools and some Free Softare projects that implement parts of it. These logs can be annotated through the software as well.Qualcomm Diag is the qualcomm diagnostics interface built into many Qualcomm based chipsets (or rather their software) for a long time (more than a decade). Using the software, users can see all the signaling messages made by their mobile devices, as the software generates a log of them. It is often used in order to facilitate product development of these devices.

It is a utility for those who have devices using Qualcomm ASICs and trial hardware, and allows them to test, evaluate and potentially diagnose issues in the RF performance of their mobile devices. What is QXDM Professional? The QXDM Professional software is also known as the Qualcomm eXtensible Diagnostic Monitor. Keep up the good work, guys! And if you like my post, please use the thanks button.
This post explains how to connect QXDM to a Samsung S4 phone: Btw I would like to praise Qualcomm for their great software.
This archive includes unpacked and cr*cked qxdm binaries for xp and 7. Af3540ad1495c4b37c2d17e601bb9076 QPST-QCAT-QXDM 3.14.414.514.594-*****ed.7z Since 3.13 or so, Qualcomm has started protecting qxdm with a packer, which is btw detected by some antivirus.
This is a fairly recent (2013) version that has a patched exe for each version (note that 3.14.594 requires an additional step, copying qlms.txt). This software is useful when you need a trace of the air interface, QXDM can capture the OTA packets and QCAT can print the contents. The following instructions are to be used to determine if your cell phone's transmit and receive. Qxdm License Crack Rating: 8,6/10 1002votes.
