Driver Exynos 9610 [2021] -

Review: Exynos 9610 — Driver & Software Support

Summary

• The Exynos 9610 is a mid‑range Samsung SoC introduced in 2018 (12 nm LPP), used in several phones (e.g., Galaxy A50, some variants of A30/A70, select OEM models). This review focuses on driver and software support: upstream availability, kernel support, graphics/VPU drivers, modem and baseband, power management, vendor blobs, developer experience, and practical implications for custom ROMs, security updates, and longevity.

Key specifications (context)

• CPU: 4x Cortex‑A73 + 4x Cortex‑A53 (big.LITTLE).
• GPU: Mali‑G72 MP3.
• Process: 10/12 nm class (Samsung LPP for 9610).
• ISP/VPU: Samsung image pipeline and video encode/decode blocks (HW HEVC/H.264 support).
• Typical use: mid‑range Android devices from 2018–2019.

1. Kernel support and upstreaming

• Mainline Linux kernel: There is no full upstream mainline support specifically tailored for Exynos 9610 platform device trees and SoC‑specific drivers in mainline as of its initial lifecycle. Samsung provides kernel sources (GPL) for each device model, usually based on older Android kernels (4.x or 4.14–4.19 era), with significant SoC patches and platform glue.
• Device trees & platform code: Device tree blobs (DTBs) and platform drivers for SoC‑specific peripherals were typically maintained in vendor branches rather than merged upstream. That affects portability to mainline kernels: developers must backport Samsung platform drivers or use vendor kernels.
• Practical effect: Custom ROMs and custom kernels typically rely on Samsung’s vendor kernel sources or substantial local patches; full mainline support requires work and often lacks GPU/ISP/PMIC integration.

2. Graphics and Mali drivers

• GPU: Mali‑G72 MP3.
• Drivers: ARM provides two driver stacks:
  • Kernel DRM drivers (panfrost or Lima origin): Panfrost upstream supports more recent Mali mid‑range GPUs, but initial support was focused on certain Mali‑Gxx variants; compatibility with G72 MP3 has progressed but depends on kernel/userland versions.
  • Binary (proprietary) Mali userspace (libmali) and kernel modules provided by Samsung historically. Many vendor images used the proprietary blobs for optimal performance and shader compiler support.
• Open‑source status: Over time, panfrost has gained G72 support; on older vendor kernels, running panfrost can require backporting driver and Mesa support. For users seeking fully open‑source GPU stack, success depends on kernel version and available panfrost support for G72 MP3 in that release.
• Performance/compatibility: Vendor blobs often give better out‑of‑the‑box performance for shipped Android releases. For custom kernels or mainline adoption, panfrost (with modern Mesa) can reach usable performance but may require kernel upgrades.

3. Multimedia (ISP, VPU) drivers

• Camera ISP: Samsung’s Image Signal Processor and camera pipeline drivers (camera HAL, vendor libs) were proprietary and tied to vendor kernels and Android camera HAL implementations. This means:
  • Camera functionality (especially advanced features, tuning, and multi‑camera support) heavily relies on proprietary blobs and vendor frameworks.
  • Porting camera support to custom ROMs or mainline kernels is nontrivial; often only basic camera functions work without vendor HALs.
• Video encode/decode: Hardware codecs (HEVC/H.264) are accessible through vendor drivers and Android’s MediaCodec path. On mainline efforts, VPU support typically requires vendor blobs or dedicated reverse‑engineered drivers; full hardware acceleration may be unavailable without them.

4. Modem, baseband, and telephony drivers

• Cellular modem firmware and associated binary blobs are tightly controlled by modem vendors and integrated into the vendor image. Kernel side uses standard interfaces (e.g., qmi, cdc‑ether, or specific serial interfaces) but userland firmware/firmware blobs are required.
• Telephony stacks and RIL (Radio Interface Layer) are vendor/userland components; custom ROMs must include working blobs and RIL implementations matching the device’s modem. No upstream open alternative provides a full replacement.

5. Power management, PMIC, and thermal drivers

• PMIC and thermal management are implemented via vendor drivers and device tree bindings. Samsung platform code includes regulators, thermal zones, and battery/charging drivers specific to the board and PMIC.
• Impact: Battery life tuning and thermal profiles are frequently handled by vendor firmware and kernel patches. Custom ROMs relying on upstream kernels may need to re‑implement or adapt regulator and thermal drivers to avoid regressions in battery life or thermal throttling.

6. Security updates and lifecycle

• Samsung provided security updates for products using Exynos 9610 during their vendor support window. However, long‑term maintenance for older mid‑range models tends to taper after ~2–3 years.
• For continued security and feature updates beyond vendor support, the community often relies on device maintainers to port newer kernels and security patches into custom ROMs — feasible but time‑consuming and varying by device popularity.

7. Vendor blobs and legality

• Samsung complied with GPL for kernel source release; nonetheless, many critical components (GPU userspace, camera firmware, modem firmware) are proprietary binary blobs. These blobs are usually redistributable in device‑specific packages but cannot be merged into mainline kernels.
• Implication for open source purists: Achieving a fully open stack on Exynos 9610 devices is challenging due to closed ISP, GPU userland (on older releases), and modem blobs. Progress in open panfrost and reverse engineering has reduced that gap but not eliminated it entirely.

8. Developer experience (custom ROMs, mainline efforts)

• For widely‑used devices (e.g., Galaxy A50), there is an active custom ROM scene. Developers typically:
  • Start from Samsung’s kernel sources and vendor blobs.
  • Backport security patches and features.
  • Attempt to replace proprietary GPU stacks with panfrost when kernel/mesa support allows.
• Mainline kernel ports exist in varying degrees; device‑specific work to support PMIC, display, camera, and audio is required.
• Complexity ranking (easiest → hardest): bootloader unlocking & recovery → basic kernel/adb functions → GPU switch to panfrost → camera/ISP full feature parity → modem/RIL replacement.

9. Performance and benchmarks (driver‑dependent)

• Stock vendor drivers: Balanced performance for mid‑range workloads; good power/perf for epoch devices, optimized for Android UI and typical apps.
• With open drivers (panfrost) on newer kernels: Comparable performance for many workloads; GPU driver maturity influences gaming/3D benchmarks. Real‑world differences depend on driver maturity at the time of deployment.

10. Practical advice

• If you need stable, full device functionality: use vendor kernel and blobs shipped for your device; this ensures camera, video, modem, and optimized GPU work.
• If you want an open stack or mainline kernel: expect to invest in backports and accept possible reduced camera or VPU functionality; panfrost can replace Mali userspace in many setups if kernel and Mesa versions support G72 MP3.
• For developers: collect Samsung’s GPL kernel sources for your specific device build, vendor proprietary blobs (firmware, GPU userspace, camera HAL, modem), and track upstream panfrost/Mesa and kernel drivers for G72 support. Use active device maintainers’ trees as a starting point.

11. Future prospects (as of 2026)

• Panfrost and upstream graphics work have matured significantly for many Mali GPUs, improving the feasibility of open drivers for Exynos‑class SoCs, but exact support for G72 MP3 depends on kernel and Mesa version.
• Community progress continues to reduce reliance on proprietary blobs for GPUs, but ISP and modem firmware remain major closed components for most phones.

Conclusion

• The Exynos 9610 platform offers a capable mid‑range hardware baseline, but driver and software support is mixed: vendor kernels and proprietary blobs provide full out‑of‑the‑box features; transitioning to mainline or fully open stacks requires significant effort, especially for camera, modem, and sometimes GPU features. For end users wanting stability and complete features, stick with vendor software; for developers and open‑source enthusiasts, the device is workable but will need sustained engineering to reach parity with vendor functionality.

If you want, I can:

• Provide instructions to locate the official Samsung kernel sources and vendor blobs for a specific Exynos 9610 device model (I will need the exact model name), or
• Summarize steps to attempt replacing the Mali vendor stack with panfrost on a modern kernel.

Guide to the Samsung Exynos 9610 Driver

The Exynos 9610 is an octa-core mobile processor designed by Samsung, released in 2018. It was notably used in the Samsung Galaxy A50, A70, and the Galaxy M40.

When users search for a "driver" for this processor, they typically fall into one of three categories:

1. Windows PC Connection: Trying to connect a phone with this processor to a computer.
2. Custom ROMs/Rooting: Installing Universal drivers for modding.
3. GPU Drivers: Updating graphics drivers for gaming.

Here is a comprehensive guide covering all aspects.

4.3 Devfreq for GPU and Bus

GPU frequency scaling is handled by the mali_dvfs module within the Mali driver. Memory bus (DREX) frequencies are managed by devfreq_exynos. A lack of proper governor tuning in early firmware led to UI stuttering—a known issue fixed in later driver revisions.

6.2 Android Custom ROMs

Popular custom ROMs like LineageOS, Havoc-OS, and Pixel Experience for the Galaxy A50 include updated vendor blobs (proprietary drivers extracted from newer Samsung firmwares). By installing these ROMs, you effectively update your driver Exynos 9610 suite to a version that might be newer than the stock ROM.

Case Study: The LineageOS 20 (Android 13) build for Exynos 9610 ships with Mali GPU driver r38p0, compared to the stock Android 11 driver r26p0. Users report a 20% improvement in UI smoothness.

8. Performance and Driver Optimization Notes

Benchmarks (Geekbench 5) on the Exynos 9610 show GPU driver overhead is ~15% higher than theoretical hardware capability, primarily due to inefficient memory bandwidth management in the mali_kbase scheduler. By adjusting the gpu_dvfs_time_interval sysfs node from 100ms to 50ms, some kernels achieve smoother frame rendering. driver exynos 9610

4. Installing device/host-side drivers (Windows/macOS/Linux)

• Android host USB drivers:
  • Windows: Install generic Google USB drivers or OEM drivers that recognize the device in ADB/Fastboot modes.
  • macOS/Linux: No special drivers usually needed for ADB; ensure udev rules on Linux to allow device access.
• On-device kernel modules:
  • If using an OEM firmware, drivers are packaged in the device kernel/initramfs. Custom kernels require compiling the kernel with proper config and device-tree for the target device.
• For GPU/ISP firmware:
  • Place vendor-provided blobs under /vendor/lib(64) and /vendor/firmware or as specified by the device manifest when building Android images.

4.1 PMIC Driver: S2MPS17

• Path: drivers/mfd/sec-core.c, drivers/regulator/s2mps17-regulator.c
• The S2MPS17 provides 28 LDOs and 6 bucks. The driver exposes these via the regulator framework, allowing the CPUFreq and devfreq subsystems to request voltage adjustments.
