The secondary CPU's reset vector needs to be set to KSEG1 for a cold boot (release from reset), or KSEG0 for a warm restart. On a cold boot KSEG0 may be unavailable (BMIPS4380), and on a warm restart KSEG1 may be unavailable (XKS01 mode on 4380 or 5000). Signed-off-by:

CPU interrupts need to be disabled on a cpu being taken down. When a cpu is hot-plugged out of the system the following sequence occurs. On the CPU where the hotplug sequence was initiated: cpu_down _cpu_down { __cpu_notify(CPU_DOWN_PREPARE __stop_machine(take_cpu_down wait for cpu to run disable code. __cpu_die } On the CPU being disabled: take_cpu_down __cpu_disable { mp_ops->cpu_disable bmips_cpu_disable clear_c0_status(IE_IRQ5) (added) cpu_notify(CPU_DYING... } Before the cpu_notifier is called with CPU_DYING, all interrupts on the dying cpu must be disabled. This guarantees that before tick_notify is called with the CPU_DYING event and sets the clock device pointer to NULL, there can not be any more clock interrupts. When this wasn't done, an unfortunately-timed timer interrupt sometimes caused hangs immediately prior to system suspend: Debug PM is not enabled.

BMIPS3300 processors do not have the hardware to support SMP, but with a small tweak, the SMP ebase relocation code allows BMIPS3300-based platforms to reuse the S2/S3 power management code from BMIPS4380-based chips. Normally this is as simple as adding one line to prom_init(): board_ebase_setup = &bmips_ebase_setup; Signed-off-by:

On some older BMIPS5200 (dual core / quad thread) platforms, the PROM code set up CPU2/CPU3 so they would be started through an NMI instead of through the ACTION register. But this was incompatible with some power management features that were later added, so the scheme was changed so that Linux is fully responsible for booting CPU2/CPU3. Signed-off-by:

The hybrid FPR scheme exists to allow for compatibility between existing FP32 code and newly compiled FP64A code. Such code should hopefully be rare in the real world, and for the moment is difficult to come across. All code except that built for the FP64 ABI can correctly execute using the hybrid FPR scheme, so debugging the hybrid FPR implementation can be eased by forcing all such code to use it. This is undesirable in general due to the trap & emulate overhead of the hybrid FPR implementation, but is a very useful option to have for debugging. Signed-off-by:

New toolchains will generate a .MIPS.abiflags section, referenced by a new PT_MIPS_ABIFLAGS program header. This section will provide information about the requirements of the ELF, including the ISA level the code is built for, the ASEs it requires, the size of various registers and its expectations of the floating point mode. This patch introduces a definition of the structure of this section and the program header, for use in a subsequent patch. Signed-off-by:

Hybrid FPRs is a scheme where scalar FP registers are 64b wide, but accesses to odd indexed single registers use bits 63:32 of the preceeding even indexed 64b register. In this mode all FP code except that built for the plain FP64 ABI can execute correctly. Most notably a combination of FP64A & FP32 code can execute correctly, allowing for existing FP32 binaries to be linked with new FP64A binaries that can make use of 64 bit FP & MSA. Hybrid FPRs are implemented by setting both the FR & FRE bits, trapping & emulating single precision FP instructions (via Reserved Instruction exceptions) whilst allowing others to execute natively. It therefore has a penalty in terms of execution speed, and should only be used when no fully native mode can be. As more binaries are recompiled to use either the FPXX or FP64(A) ABIs, the need for hybrid FPRs should diminish. However in the short to mid term it allows for a gradual transition towards that world, rather than a complete ABI break which is not feasible for some users & not desirable for many. A task will be executed using the hybrid FPR scheme when its TIF_HYBRID_FPREGS flag is set & TIF_32BIT_FPREGS is clear. A further patch will set the flags as necessary, this patch simply adds the infrastructure necessary for the hybrid FPR mode to work. Signed-off-by:

MIPS is introducing new variants of its O32 ABI which differ in their handling of floating point, in order to enable a gradual transition towards a world where mips32 binaries can take advantage of new hardware features only available when configured for certain FP modes. In order to do this ELF binaries are being augmented with a new section that indicates, amongst other things, the FP mode requirements of the binary. The presence & location of such a section is indicated by a program header in the PT_LOPROC ... PT_HIPROC range. In order to allow the MIPS architecture code to examine the program header & section in question, pass all program headers in this range to an architecture-specific arch_elf_pt_proc function. This function may return an error if the header is deemed invalid or unsuitable for the system, in which case that error will be returned from load_elf_binary and upwards through the execve syscall. A means is required for the architecture code to make a decision once it is known that all such headers have been seen, but before it is too late to return from an execve syscall. For this purpose the arch_check_elf function is added, and called once, after all PT_LOPROC to PT_HIPROC headers have been passed to arch_elf_pt_proc but before the code which invoked execve has been lost. This enables the architecture code to make a decision based upon all the headers present in an ELF binary and its interpreter, as is required to forbid conflicting FP ABI requirements between an ELF & its interpreter. In order to allow data to be stored throughout the calls to the above functions, struct arch_elf_state is introduced. Finally a variant of the SET_PERSONALITY macro is introduced which accepts a pointer to the struct arch_elf_state, allowing it to act based upon state observed from the architecture specific program headers.

Load the program headers of an ELF interpreter early enough in load_elf_binary that they can be examined before it's too late to return an error from an exec syscall.

load_elf_binary & load_elf_interp both load program headers from an ELF executable in the same way, duplicating the code. This patch introduces a helper function (load_elf_phdrs) which performs this common task & calls it from both load_elf_binary & load_elf_interp. In addition to reducing code duplication, this is part of preparing to load the ELF interpreter headers earlier such that they can be examined before it's too late to return an error from an exec syscall.

CPUFreq driver need external timer, so add hpet at first. In Loongson 3, only Core-0 can receive external interrupt. As a result, timekeeping cannot absolutely use HPET timer. We use a hybrid solution: Core-0 use HPET as its clock event device, but other cores still use MIPS; clock source is global and doesn't need interrupt, so use HPET. Signed-off-by:

Machtypes of Loongson-3 machines become more and more, but there are only small differences among different machtypes. Keeping a large table of machtypes is very ugly and hard to extend. We found that the major machtype differences are UARTs information (number of UARTs, UART IRQs, UART clocks, etc.), platform devices (EC, temperature sensors, fan controllers, etc.) and some workarounds (because of some CPU bugs or mainboard bugs). In this patch we improve the UEFI-like (LEFI) interface to make all Loongson-3 machines use a same machtype "generic-loongson-machine". Signed-off-by:

The width of HT-bus is only 40-bit, but Loongson-3 has 48-bit physical address. This implies only node-0's memory is DMAable because high bits (Node ID) will lost. Fortunately, by configuring address windows in firmware, we can extract 2bit Node ID (bit 44~47, only bit 44~45 used now) from Loongson-3's 48-bit address space and embed it into 40-bit (bit 37~38). Every NUMA node can do DMA now (however, maximum memory of each node is reduced to 2^37 = 128GB). Signed-off-by:
