2025-04-28KVM: arm64: Unconditionally cross check hyp stateQuentin Perret1-15/+9
Now that the hypervisor's state is stored in the hyp_vmemmap, we no longer need an expensive page-table walk to read it. This means we can now afford to cross check the hyp-state during all memory ownership transitions where the hyp is involved unconditionally, hence avoiding problems such as [1].

2025-04-28KVM: arm64: Defer EL2 stage-1 mapping on shareQuentin Perret1-7/+16
We currently blindly map into EL2 stage-1 *any* page passed to the __pkvm_host_share_hyp() HVC. This is less than ideal from a security perspective as it makes exploitation of potential hypervisor gadgets easier than it should be. But interestingly, pKVM should never need to access SHARED_BORROWED pages that it hasn't previously pinned, so there is no need to map the page before that.

2025-04-28KVM: arm64: Move hyp state to hyp_vmemmapQuentin Perret3-33/+53
Tracking the hypervisor's ownership state into struct hyp_page has several benefits, including allowing far more efficient lookups (no page-table walk needed) and de-corelating the state from the presence of a mapping. This will later allow to map pages into EL2 stage-1 less proactively which is generally a good thing for security. And in the future this will help with tracking the state of pages mapped into the hypervisor's private range without requiring an alias into the 'linear map' range.

2025-04-28KVM: arm64: Use 0b11 for encoding PKVM_NOPAGEQuentin Perret1-3/+1
The page ownership state encoded as 0b11 is currently considered reserved for future use, and PKVM_NOPAGE uses bit 2. In order to simplify the relocation of the hyp ownership state into the vmemmap in later patches, let's use the 'reserved' encoding for the PKVM_NOPAGE state. The struct hyp_page layout isn't guaranteed stable at all, so there is no real reason to have 'reserved' encodings. No functional changes intended.

2025-04-27MIPS: Fix idle VS timer enqueueMarco Crivellari3-35/+37
MIPS re-enables interrupts on its idle routine and performs a TIF_NEED_RESCHED check afterwards before putting the CPU to sleep. The IRQs firing between the check and the 'wait' instruction may set the TIF_NEED_RESCHED flag. In order to deal with this possible race, IRQs interrupting __r4k_wait() rollback their return address to the beginning of __r4k_wait() so that TIF_NEED_RESCHED is checked again before going back to sleep. However idle IRQs can also queue timers that may require a tick reprogramming through a new generic idle loop iteration but those timers would go unnoticed here because __r4k_wait() only checks TIF_NEED_RESCHED. It doesn't check for pending timers. Fix this with fast-forwarding idle IRQs return address to the end of the idle routine instead of the beginning, so that the generic idle loop handles both TIF_NEED_RESCHED and pending timers. CONFIG_CPU_MICROMIPS has been removed along with the nop instructions. There, NOPs are 2 byte in size, so change the code with 3 _ssnop which are always 4 byte and remove the ifdef. Added ehb to make sure the hazard is always cleared. Fixes: c65a5480ff29 ("[MIPS] Fix potential latency problem due to non-atomic cpu_wait.")

2025-04-27Revert "arm64: dts: allwinner: h6: Use RSB for AXP805 PMIC connection"Jernej Skrabec3-37/+37
This reverts commit 531fdbeedeb89bd32018a35c6e137765c9cc9e97. Hardware that uses I2C wasn't designed with high speeds in mind, so communication with PMIC via RSB can intermittently fail. Go back to I2C as higher speed and efficiency isn't worth the trouble.

2025-04-27arm64: dts: allwinner: a523: add X96Q-Pro+ supportAndre Przywara2-0/+288
The X96QPro+ is a TV box using the Allwinner H728 SoC. That SoC seems to be a package variant of the A523 family, at least it uses the same SoC ID and is compatible as far as we can assess. It comes with the following specs: - Allwinner H728 SoC: 8 Arm Cortex-A55 cores, Mali-G57 MC1 GPU - 2 or 4GiB DDR3L DRAM - 32, 64, or 128 GiB eMMC flash - AXP717 + AXP323 PMICs - Gigabit Ethernet (using MAXIO PHY) - HDMI port - 2 * USB 2.0 ports - 1 * USB 3.0 port - microSD card slot - TOSLINK digital audio output - 3.5mm A/V port - infrared sensor - 7-segment display - 5V barrel plug power supply - power button The PCB provides holes for soldering a UART header or cable, this is connected to the debug UART0. There is another set of UART pins available. The board also features a FEL button (accessible through the 3.5mm socket) and a reset button (only accessible when case is open). This .dts just describes the basic peripherals as far as we support them at the moment. The PMIC rail assignments are reverse engineered as far as possible, by dumping them from a running Android system, and correlating them to other boards using the same SoC.

The Avaota A1 router board is an Open Source hardware board, designed by YuzukiHD. Pine64 produces some boards and sells them. It uses the Allwinner A527 or T527 SoC, and comes with the following features: - Eight ARM Cortex-A55 cores, Mali-G57 MC1 GPU - 1GiB/2GiB/4GiB LPDDR4 DRAM - AXP717 + AXP323 PMIC - Raspberry-Pi-2 compatible GPIO header - 1 USB 2.0 type A host port, 1 USB 3.0 type A host post - 1 USB 2.0 type C port (OTG + serial debug) - MicroSD slot - eMMC between 16 and 128 GiB - on-board 16MiB bootable SPI NOR flash - two 1Gbps Ethernet ports (via RTL8211F PHYs) - HDMI port - DP port - camera and LCD connectors - 3.5mm headphone jack - (yet) unsupported WiFi/BT chip - 1.3" LC display, connected via SPI - 12 V barrel plug for power supply Add the devicetree file describing the currently supported features.

2025-04-27arm64: dts: rockchip: Assign RT5616 MCLK rate on rk3588-friendlyelec-cm3588Tom Vincent1-0/+4
The Realtek RT5616 audio codec on the FriendlyElec CM3588 module fails to probe correctly due to the missing clock properties. This results in distorted analogue audio output. Assign MCLK to 12.288 MHz, which allows the codec to advertise most of the standard sample rates per other RK3588 devices.
