2025-01-31accel/qaic: Add AIC200 supportJeffrey Hugo
Add basic support for the new AIC200 product. The PCIe Device ID is 0xa110. With this, we can turn on the lights for AIC200 by leveraging much of the existing driver.

Pull drm updates from Dave Airlie: "This contains two major new drivers: - imagination is a first driver for Imagination Technologies devices, it only covers very specific devices, but there is hope to grow it - xe is a reboot of the i915 GPU (shares display) side using a more upstream focused development model, and trying to maximise code sharing. It's not enabled for any hw by default, and will hopefully get switched on for Intel's Lunarlake. This also drops a bunch of the old UMS ioctls. It's been dead long enough. amdgpu has a bunch of new color management code that is being used in the Steam Deck. amdgpu also has a new ACPI WBRF interaction to help avoid radio interference.

2023-12-15accel/qaic: Implement quirk for SOC_HW_VERSIONJeffrey Hugo
The SOC_HW_VERSION register in the BHI space is not correctly initialized by the device and in many cases contains uninitialized data. The register could contain 0xFFFFFFFF which is a special value to indicate a link error in PCIe, therefore if observed, we could incorrectly think the device is down. Intercept reads for this register, and provide the correct value - every production instance would read 0x60110200 if the device was operating as intended.

2023-12-01accel/qaic: Expand DRM device lifecycleCarl Vanderlip
Currently the QAIC DRM device registers itself when the MHI QAIC_CONTROL channel becomes available. This is when the device is able to process workloads. However, the DRM driver also provides the debugfs interface bootlog for the device. If the device fails to boot to the QSM (which brings up the MHI QAIC_CONTROL channel), the bootlog won't be available for debugging why it failed to boot. Change when the DRM device registers itself from when QAIC_CONTROL is available to when the card is first probed on the PCI bus. Additionally, make the DRM driver persist through reset/error cases so the driver doesn't have to be reloaded to access the card again. Send KOBJ_ONLINE/OFFLINE uevents so userspace can know when DRM device is ready to handle requests.

2023-10-27accel/qaic: Add support for periodic timesyncAjit Pal Singh
Device and Host have a time synchronization mechanism that happens once during boot when device is in SBL mode. After that, in mission-mode there is no timesync. In an experiment after continuous operation, device time drifted w.r.t. host by approximately 3 seconds per day. This drift leads to mismatch in timestamp of device and Host logs. To correct this implement periodic timesync in driver. This timesync is carried out via QAIC_TIMESYNC_PERIODIC MHI channel.

2023-10-27accel/qaic: Enable 1 MSI fallback modeCarl Vanderlip
Several virtualization use-cases either don't support 32 MultiMSIs (Xen/VMware) or have significant drawbacks to their use (KVM's vIOMMU, which is required to support 32 MSI, needs to allocate an alternate system memory space for each device using vIOMMU (e.g. 8GB VM mem and 2 cards => 8 + 2 * 8 = 24GB host memory required)). Support these cases by enabling a 1 MSI fallback mode. Whenever all 32 MSIs requested are not available, a second request for a single MSI is made. Its success is the initiator of single MSI mode. This mode causes all interrupts generated by the device to be directed to the 0th MSI (firmware >=v1.10 will do this as a response to the PCIe MSI capability configuration). Likewise, all interrupt handlers for the device are registered to the 0th MSI. Since the DBC interrupt handler checks if the DBC is in use or if there is any pending changes, the 'spurious' interrupts are disregarded. If there is work to be done, the standard threaded IRQ handler is dispatched. On every interrupt, the MHI handler wakes up its threaded interrupt handler, and attempts to wake any waiters for MHI state events. Performance is within +-0.6% for test cases that typify real world use. Larger differences ([-4,+132]%, avg +47%) exist for very simple tasks (e.g. addition) compiled for single NSPs. It is assumed that the small work and many interrupts typically cause contention (e.g. 16 NSPs vs 4 CPUs), as evidenced by the standard deviation between runs also decreasing (r=-0.48 between delta(Performace_test) and delta(StdDev_test/Avg_test)) Signed-off-by: Carl Vanderlip <quic_carlv@quicinc.com> Reviewed-by: Pranjal Ramajor Asha Kanojiya <quic_pkanojiy@quicinc.com> Reviewed-by: Jeffrey Hugo <quic_jhugo@quicinc.com> Signed-off-by: Jeffrey Hugo <quic_jhugo@quicinc.com> Reviewed-by: Stanislaw Gruszka <stanislaw.gruszka@linux.intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20231016170036.5409-1-quic_jhugo@quicinc.com
2023-04-06accel/qaic: Add MHI controllerJeffrey Hugo
An AIC100 device contains a MHI interface with a number of different channels for controlling different aspects of the device. The MHI controller works with the MHI bus to enable and drive that interface. AIC100 uses the BHI protocol in PBL to load SBL. The MHI controller expects the SBL to be located at /lib/firmware/qcom/aic100/sbl.bin and expects the MHI bus to manage the process of loading and sending SBL to the device.
