mainline inclusion from mainline-v6.16-rc1 commit ca1a66c category: feature bugzilla: RVCK-Project#177 -------------------------------- Doing misaligned access to userspace memory would make a trap on platform where it is emulated. Latest fixes removed the kernel capability to do unaligned accesses to userspace memory safely since interrupts are kept disabled at all time during that. Thus doing so would crash the kernel. Such behavior was detected with GET_UNALIGN_CTL() that was doing a put_user() with an unsigned long* address that should have been an unsigned int*. Reenabling kernel misaligned access emulation is a bit risky and it would also degrade performances. Rather than doing that, we will try to avoid any misaligned accessed by using copy_from/to_user() which does not do any misaligned accesses. This can be done only for !CONFIG_HAVE_EFFICIENT_UNALIGNED_ACCESS and thus allows to only generate a bit more code for this config.

mainline inclusion from mainline-v6.19-rc1 commit 14ff9e5 category: feature bugzilla: RVCK-Project#71 -------------------------------- Optimize the PLIC driver by maintaining the interrupt enable state in the handler's enable_save array during normal operation rather than only during suspend/resume. This eliminates the need to read enable registers during suspend and makes the enable state immediately available for other purposes. Let __plic_toggle() update both the hardware registers and the cached enable_save state atomically within the existing enable_lock protection. That allows to remove the suspend-time enable register reading since handler::enable_save now always reflects the current state.

mainline inclusion from mainline-v6.19-rc1 commit 539d147 category: feature bugzilla: RVCK-Project#71 -------------------------------- Add a new compatible for the plic found in UltraRISC DP1000 with a quirk to work around a known hardware bug with IRQ claiming in the UR-CP100 cores. When claiming an interrupt on UR-CP100 cores, all other interrupts must be disabled before the claim register is accessed to prevent incorrect handling of the interrupt. This is a hardware bug in the CP100 core implementation, not specific to the DP1000 SoC. When the PLIC_QUIRK_CP100_CLAIM_REGISTER_ERRATUM flag is present, a specialized handler (plic_handle_irq_cp100) disables all interrupts except for the first pending one before reading the claim register, and then restores the interrupts before further processing of the claimed interrupt continues. This implementation leverages the enable_save optimization, which maintains the current interrupt enable state in memory, avoiding additional register reads during the workaround. The driver matches on "ultrarisc,cp100-plic" to apply the quirk to all SoCs using UR-CP100 cores, regardless of the specific SoC implementation. This has no impact on other platforms.

The whole thing is less than 1000 lines, and it's a pain to bounce back and forth between two files. Several portdrv_core.c functions were non-static because they were referenced from portdrv_pci.c. Make them static since they're now all in portdrv.c. No functional change intended.

mainline inclusion from mainline-6.14-rc7 commit 4b455f5 category: feature bugzilla: RVCK-Project#178 -------------------------------- Currently if architectures want to support HOTPLUG_SMT they need to provide a topology_is_primary_thread() telling the framework which thread in the SMT cannot offline. However arm64 doesn't have a restriction on which thread in the SMT cannot offline, a simplest choice is that just make 1st thread as the "primary" thread. So just make this as the default implementation in the framework and let architectures like x86 that have special primary thread to override this function (which they've already done). There's no need to provide a stub function if !CONFIG_SMP or !CONFIG_HOTPLUG_SMT. In such case the testing CPU is already the 1st CPU in the SMT so it's always the primary thread.

Instead using a temporary xarray to record the heterogeneous information (from ACPI_PPTT_ACPI_IDENTICAL) and SMT information of the first core in its heterogeneous CPU cluster when building the topology.

mainline inclusion from Linux 6.7-rc1 commit 0d3f0e6 category: feature bugzilla: RVCK-Project#108 -------------------------------- parse_events_terms() existed in function names but was passed a 'struct list_head'. As many parse_events functions take an evsel_config list as well as a parse_event_term list, and the naming head_terms and head_config is inconsistent, there's a potential to switch the lists and get errors. Introduce a 'struct parse_events_terms', that just wraps a list_head, to avoid this. Add the regular init/exit functions and transition the code to use them.

mainline inclusion from Linux 7.0-rc3 commit e4b3cbd category: feature bugzilla: RVCK-Project#233 -------------------------------- The T-Head TH1520 SoC uses an E902 co-processor running Always-On (AON) firmware to manage power, clock, and other system resources [1]. This patch introduces a driver implementing the AON firmware protocol, allowing the Linux kernel to communicate with the firmware via mailbox channels. Through an RPC-based interface, the kernel can initiate power state transitions, update resource configurations, and perform other AON-related tasks.

mainline inclusion from Linux 7.0-rc3 commit 2bae46e category: feature bugzilla: RVCK-Project#233 -------------------------------- The T-Head TH1520 SoC contains multiple power islands that can be programmatically turned on and off using the AON (Always-On) protocol and a hardware mailbox [1]. The relevant mailbox driver has already been merged into the mainline kernel in commit 5d4d263 ("mailbox: Introduce support for T-head TH1520 Mailbox driver"); Introduce a power-domain driver for the TH1520 SoC, which is using AON firmware protocol to communicate with E902 core through the hardware mailbox. This way it can send power on/off commands to the E902 core. The interaction with AUDIO power island e.g trying to turn it OFF proved to crash the firmware running on the E902 core. Introduce the workaround to disable interacting with the power island.
