Msm8953 For Arm64 Driver -

The long-term solution is not Android, but PostmarketOS or Ubuntu Touch with upstream Linux. The linux-next kernel now includes basic qcom-msm8953.dtsi support. The following drivers are already mainlined:

Not yet mainlined:

Realistically, a fully functional mainline Linux ARM64 desktop on MSM8953 is 2-3 years away – but the progress is tangible.

Let’s say you need to rebuild the WiFi driver for a custom ARM64 kernel.

Prerequisites:

Steps:

Error handling: If you see Required key not available, disable CONFIG_MODULE_SIG_FORCE.

CONFIG_QCOM_QMI_HELPERS=m # Stick to module CONFIG_QCOM_RMTFS_MEM=y # Only if you have rmtfs service in userspace

Device Tree: Base your .dts on qcom-msm8953.dtsi from the mainline kernel (it exists but is minimal). You will need to copy bindings from the CAF kernel’s arch/arm64/boot/dts/qcom/. msm8953 for arm64 driver

If your goal is mainline Linux on MSM8953 (e.g., postmarketOS, bootlin, or generic ARM64 distro):

✅ Good enough for:

❌ Not ready for:

From your device’s stock ROM (Android 9 typically), extract /vendor partition. Then separate:

For the camera HAL, you may need to use libhwbinder’s 32-bit service:

service cameraserver /system/bin/cameraserver
    class main
    user cameraserver
    # Force 32-bit execution
    environment LD_LIBRARY_PATH /vendor/lib:/system/lib

What is MSM8953?

MSM8953 is a Qualcomm Snapdragon processor, specifically a 64-bit octa-core processor based on ARMv8 architecture. It's commonly used in mid-range Android devices. The long-term solution is not Android, but PostmarketOS

Driver Overview

The MSM8953 driver is a software component that enables communication between the operating system (OS) and the hardware components of the processor. The driver provides a set of APIs that allow the OS to interact with the processor's peripherals, such as GPU, memory, and I/O interfaces.

ARM64 Architecture

ARM64, also known as AArch64, is a 64-bit instruction set architecture (ISA) developed by ARM Holdings. It's used in many modern processors, including the MSM8953. ARM64 provides a large address space, improved performance, and increased security features compared to its 32-bit predecessor.

MSM8953 Driver for ARM64

To develop or use the MSM8953 driver on an ARM64-based system, you'll need to focus on the following key aspects:

Code Example

Here's a simple example of a kernel module that interacts with the MSM8953 processor on ARM64:

#include <linux/module.h>
#include <linux/init.h>
MODULE_LICENSE("GPL");
MODULE_AUTHOR("Your Name");
MODULE_DESCRIPTION("MSM8953 Test Driver");
static int __init msm8953_test_init(void)
printk(KERN_INFO "MSM8953 test driver initialized\n");
    // Add your MSM8953-specific code here
    return 0;
static void __exit msm8953_test_exit(void)
printk(KERN_INFO "MSM8953 test driver exited\n");
module_init(msm8953_test_init);
module_exit(msm8953_test_exit);

This example initializes a kernel module and prints a message to the kernel log. You'll need to add your MSM8953-specific code to interact with the processor's hardware components.

By understanding the MSM8953 processor, ARM64 architecture, and kernel driver development, you'll be well-equipped to create efficient and effective drivers for your specific use case.

Title: Demystifying the MSM8953 for ARM64: A Driver Architecture Overview

The MSM8953, widely known as the Qualcomm Snapdragon 625, is a mid-range System-on-Chip (SoC) that gained massive popularity due to its balance of performance and power efficiency. When discussing "MSM8953 for arm64 driver" support, we are typically referring to the low-level software stack required to boot and operate hardware based on this SoC, particularly within the Linux kernel environment (such as on Android devices or embedded Linux systems).

Here is a breakdown of the driver landscape for the MSM8953 on the ARM64 architecture.
