This patch series adds support for the kv3-1 CPU architecture of the kvx family
found in the Coolidge (aka MPPA3-80) SoC of Kalray.
This is an RFC, since kvx support is not yet upstreamed into gcc/binutils,
therefore this patch series cannot be merged into Linux for now.
The goal is to have preliminary reviews and to fix problems early.
The Kalray VLIW processor family (kvx) has the following features:
* 32/64 bits execution mode
* 6-issue VLIW architecture
* 64 x 64bits general purpose registers
* SIMD instructions
* little-endian
* deep learning co-processor
Kalray kv3-1 core which is the third of the kvx family is embedded in Kalray
Coolidge SoC currently used on K200 and K200-LP boards.
The Coolidge SoC contains 5 clusters each of which is made of:
* 4MiB of on-chip memory (SMEM)
* 1 dedicated safety/security core (kv3-1 core).
* 16 PEs (Processing Elements) (kv3-1 cores).
* 16 Co-processors (one per PE)
* 2 Crypto accelerators
The Coolidge SoC contains the following features:
* 5 Clusters
* 2 100G Ethernet controllers
* 8 PCIe GEN4 controllers (Root Complex and Endpoint capable)
* 2 USB 2.0 controllers
* 1 Octal SPI-NOR flash controller
* 1 eMMC controller
* 3 Quad SPI controllers
* 6 UART
* 5 I2C controllers (3 of which are SMBus capable)
* 4 CAN controllers
* 1 OTP memory
A kvx toolchain can be built using:
# install dependencies: texinfo bison flex libgmp-dev libmpc-dev libmpfr-dev
$ git clone https://github.com/kalray/build-scripts
$ cd build-scripts
$ source last.refs
$ ./build-kvx-xgcc.sh output
The kvx toolchain will be installed in the "output" directory.
You can also find prebuilt toolchains at: https://github.com/kalray/build-scripts/releases/tag/v4.11.1
They are built for Ubuntu 18.04, 20.04 and 22.04 (named 'latest').
A buildroot image (kernel+rootfs) and toolchain can be built using:
$ git clone -b coolidge-for-upstream-v2 https://github.com/kalray/buildroot
$ cd buildroot
$ make O=build_kvx kvx_defconfig
$ make O=build_kvx
The vmlinux image can be found in buildroot/build_kvx/images/vmlinux.
If you are just interested in building the Linux kernel with no rootfs you can
just do this with the kvx-elf- toolchain:
$ make ARCH=kvx O=build_kvx CROSS_COMPILE=kvx-elf- defconfig
$ make ARCH=kvx O=build_kvx CROSS_COMPILE=kvx-elf- -j$(($(nproc) + 1))
The vmlinux ELF can be run with qemu by doing:
# install dependencies: ninja pkg-config libglib-2.0-dev cmake libfdt-dev libpixman-1-dev zlib1g-dev
$ git clone https://github.com/kalray/qemu-builder
$ cd qemu-builder
$ git submodule update --init
$ make -j$(($(nproc) + 1))
$ ./qemu-system-kvx -m 1024 -nographic -kernel <path/to/vmlinux>
V1 -> V2:
- Rebase on 6.1.6
- Removed features that are non-necessary for basic port to boot: kgdb, l2 cache driver, jump label, ftrace, hw breakpoints, gdb python helpers and perf monitors
- Split dt bindings in separate patches
- Split irqchip drivers: 1 driver == 1 patch
- Fixed typos in arch/kvx/Kconfig
- Rewrote ASM atomic helpers in C using builtins
- Documentation has been rewritten in RST format and included in documentation build system
- Renamed default_defconfig to defconfig
- Removed arch-specific __access_ok to use generic code
- Fixed make clean issue caused by LIBGCC definition in arch/kvx/Makefile
Note that all remarks on V1 patchset are not addressed yet. We are still working on some fixes like removing legacy syscalls,
using generic entry, rework smp.c and publication of kv3-1 ABI specification.

You should rewrite this as:
current->stack_canary = get_random_canary();
__stack_chk_guard = current->stack_canary;
which is what the other archs all now do. (They didn't used to, and this
looks like it's simply based on older code.)

Glad to see this CPU has a cycle counter. Out of curiosity, what is
its resolution?
Also, related, does this CPU happen to have a "RDRAND"-like instruction?
(I don't know anything about kvx or even what it is.)

Coolidge v1 SoC has 5 clusters of 17 kvx cores:
- 16 application cores aka PE
- 1 privileged core, the Resource Manager, aka RM.
Linux can run in SMP config on the 16 cores of a Cluster.
Memory coherency between all cores is guarenteed by the L2 cache.

V1 -> V2:
- removed L2 cache driver
- removed ipi and pwr-ctrl driver (splitted in their own patch)

2.37.2
Each Cluster of the Coolidge SoC includes an Advanced Programmable
Interrupt Controller (APIC) and Generic Interrupt Controller (GIC).
The APIC GIC acts as an intermediary interrupt controller, muxing/routing
incoming interrupts to cores in the cluster.
The 139 possible input interrupt lines are organized as follow:
- 128 from the mailbox controller (one it per mailboxes)
- 1 from the NoC router
- 5 from IOMMUs
- 1 from L2 cache DMA job FIFO
- 1 from cluster watchdog
- 2 for SECC, DECC
- 1 from Data NoC
The 72 possible output interrupt line:
- 68 : 4 interrupts per cores (17 cores)
- 1 for L2 cache controller
- 3 extra that are for padding

From: Jules Maselbas <[email protected]>
Each kvx core includes a hardware interrupt controller (core INTC)
with the following features:
- 32 independent interrupt sources
- 4-bit priotity level
- Individual interrupt enable bit
- Interrupt status bit displaying the pending interrupts
- Priority management between the 32 interrupts
Among those 32 interrupt sources, the first are hard-wired to hardware
sources. The remaining interrupt sources can be triggered via software
by directly writing to the ILR SFR.
The hard-wired interrupt sources are the following:
0: Timer 0
1: Timer 1
2: Watchdog
3: Performance Monitors

The APIC GIC lines will be used to route interrupts coming from SoC
peripherals from outside the Cluster to the kvx core. Those peripherals
include USB host controller, eMMC/SD host controller, i2c, spi, PCIe,
IOMMUs etc...

+ * Optimized memset for kvx architecture
+ *
+ * In order to optimize memset on kvx, we can use various things:
+ * - conditionnal store which avoid branch penalty
+ * - store half/word/double/quad/octuple to store up to 16 bytes at a time
+ * - dzerol to zero a cacheline when the pattern is '0' (often the case)
+ * - hardware loop for steady cases.
+ *
+ * First, we assume that memset is mainly used for zeroing areas. In order
+ * to optimize this case, we consider it to be the fast path of the algorithm.
+ * In both cases (0 and non 0 pattern), we start by checking if the size is
+ * below a minimum size. If so, we skip the alignment part. Indeed, the kvx
+ * supports misalignment and the penalty for letting it do unaligned accesses is
+ * lower than trying to realigning us. So for small sizes, we don't even bother
+ * to realign. Minor difference is that in the memset with 0, we skip after the
+ * dzerol loop since dzerol must be cache-line aligned (no misalignment of
+ * course).
+ * Regarding the non 0 pattern memset, we use sbmm to replicate the pattern on
+ * all bits on a register in one call.
+ * Once alignment has been reached, we can do the hardware loop for both cases(
+ * store octuple/dzerol) in order to optimize throughput. Care must be taken to
+ * align hardware loops on at least 8 bytes for performances.
+ * Once the main loop has been done, we finish the copy by checking length to do
+ * the necessary calls to store remaining bytes.
+ *
+ * Pseudo code (applies for non 0 pattern):
+ *
+ * int memset(void *dest, char pattern, long length)
+ * {
+ * long dest_align = -((long) dest);
+ * long copy;
+ * long orig_dest = dest;
+ *
+ * uint64_t pattern = sbmm8(pattern, 0x0101010101010101);
+ * uint128_t pattern128 = pattern << 64 | pattern;
+ * uint256_t pattern128 = pattern128 << 128 | pattern128;
+ *
+ * // Keep only low bits
+ * dest_align &= 0x1F;
+ * length -= dest_align;
+ *
+ * // Byte align
+ * copy = align & (1 << 0);
+ * if (copy)
+ * *((u8 *) dest) = pattern;
+ * dest += copy;
+ * // Half align
+ * copy = align & (1 << 1);
+ * if (copy)
+ * *((u16 *) dest) = pattern;

+ * // Word align
+ * copy = align & (1 << 2);

+/*
+ * kvx optimized strlen
+ *
+ * This implementation of strlen only does aligned memory accesses.
+ * Since we don't know the total length the idea is to do double word
+ * load and stop on the first null byte found. As it's always safe to
+ * read more up to a lower 8-bytes boundary.
+ *
+ * This implementation of strlen uses a trick to detect if a double
+ * word contains a null byte [1]:
+ *
+ * > #define haszero(v) (((v) - 0x01010101UL) & ~(v) & 0x80808080UL)
+ * > The sub-expression (v - 0x01010101UL), evaluates to a high bit set
+ * > in any byte whenever the corresponding byte in v is zero or greater
+ * > than 0x80. The sub-expression ~v & 0x80808080UL evaluates to high
+ * > bits set in bytes where the byte of v doesn't have its high bit set
+ * > (so the byte was less than 0x80). Finally, by ANDing these two sub-
+ * > expressions the result is the high bits set where the bytes in v
+ * > were zero, since the high bits set due to a value greater than 0x80
+ * > in the first sub-expression are masked off by the second.
+ *
+ * [1] http://graphics.stanford.edu/~seander/bithacks.html#ZeroInWord
+ *
+ * A second trick is used to get the exact number of characters before
+ * the first null byte in a double word:
+ *
+ * clz(sbmmt(zero, 0x0102040810204080))
+ *
+ * This trick uses the haszero result which maps null byte to 0x80 and
+ * others value to 0x00. The idea is to count the number of consecutive
+ * null byte in the double word (counting from less significant byte
+ * to most significant byte). To do so, using the bit matrix transpose
+ * will "pack" all high bit (0x80) to the most significant byte (MSB).
+ * It is not possible to count the trailing zeros in this MSB, however
+ * if a byte swap is done before the bit matrix transpose we still have
+ * all the information in the MSB but now we can count the leading zeros.
+ * The instruction sbmmt with the matrix 0x0102040810204080 does exactly
+ * what we need a byte swap followed by a bit transpose.
+ *
+ * A last trick is used to handle the first double word misalignment.
+ * This is done by masking off the N lower bytes (excess read) with N
+ * between 0 and 7. The mask is applied on haszero results and will
+ * force the N lower bytes to be considered not null.
+ *
+ * This is a C implementation of the algorithm described above:
+ *
+ * size_t strlen(char *s) {
+ * uint64_t *p = (uint64_t *)((uintptr_t)s) & ~0x7;
+ * uint64_t rem = ((uintptr_t)s) % 8;
+ * uint64_t low = -0x0101010101010101;
+ * uint64_t high = 0x8080808080808080;
+ * uint64_t dword, zero;
+ * uint64_t msk, len;
+ *
+ * dword = *p++;
+ * zero = (dword + low) & ~dword & high;
+ * msk = 0xffffffffffffffff << (rem * 8);
+ * zero &= msk;
+ *
+ * while (!zero) {
+ * dword = *p++;
+ * zero = (dword + low) & ~dword & high;
+ * }
+ *
+ * zero = __builtin_kvx_sbmmt8(zero, 0x0102040810204080);
+ * len = ((void *)p - (void *)s) - 8;
+ * len += __builtin_kvx_clzd(zero);
+ *
+ * return len;

2.37.2
From: Jules Maselbas <[email protected]>
The APIC includes a mailbox controller, containing 128 mailboxes.
Each mailbox is a word of 8 bytes in the controller internal memory.
Each mailbox can be independently configured with a trigger condition
and an input function.
After a write to a mailbox if the mailbox's trigger condition is met
then an interrupt will be generated.
Since this hardware block generates IRQs based on writes at some memory
locations, it is both an interrupt controller and an MSI controller.

If you already ran 'make dt_binding_check' and didn't see the above
error(s), then make sure 'yamllint' is installed and dt-schema is up to
date:
pip3 install dtschema --upgrade
Please check and re-submit after running the above command yourself. Note
that DT_SCHEMA_FILES can be set to your schema file to speed up checking
your schema. However, it must be unset to test all examples with your schema.

All the usual comments plus - wrong directory. Power controllers go to

I really doubt that you tested it... Examples are not run with address

Nope, big no.
Drivers go to drivers, not to arch code. Use proper driver infrastructure.

What about cpufreq? I don't think this is useful.

+description: |
+ Each cluster in the Coolidge SoC includes an Advanced Programmable Interrupt
+ Controller (APIC) which is split in two part:
+ - a Generic Interrupt Controller (referred as APIC-GIC)
+ - a Mailbox Controller (referred as APIC-Mailbox)
+ The APIC-Mailbox contains 128 mailboxes of 8 bytes (size of a word),
+ this hardware block is basically a 1 KB of smart memory space.
+ Each mailbox can be independently configured with a trigger condition
+ and an input mode function.
+
+ Input mode are:
+ - write
+ - bitwise OR
+ - add
+
+ Interrupts are generated on a write when the mailbox content value
+ match the configured trigger condition.
+ Available conditions are:
+ - doorbell: always raise interruption on write
+ - match: when the mailbox's value equal the configured trigger value
+ - barrier: same as match but the mailbox's value is cleared on trigger
+ - threshold: when the mailbox's value is greater than, or equal to, the
+ configured trigger value

+title: Kalray kv3-1 Inter-Processor Interrupt Controller (IPI)
+
+description: |
+ The Inter-Processor Interrupt Controller (IPI) provides a fast synchronization
+ mechanism to the software. It exposes eight independent set of registers that
+ can be use to notify each processor in the cluster.
+ A set of registers contains two 32-bit registers:
+ - 17-bit interrupt control, one bit per core, raise an interrupt on write
+ - 17-bit mask, one per core, to enable interrupts
+
+ Bit at offsets 0 to 15 selects cores in the cluster, respectively PE0 to PE15,
+ while bit at offset 16 is for the cluster Resource Manager (RM) core.
+
+ The eight output interrupts are connected to each processor core interrupt
+ controller (intc).

+ * For that purpose, it is called directly from trap_handle after saving

+ * To avoid taking nomapping while accessing page tables inside this

+ * This allows to avoid computing a complete task switching in order

+ *
+ * We refill the JTLB which contains 128 sets with 4 way each.
+ * Currently, the way selection is done using a round robin algorithm.
+ *
+ * The refill is using the basic flow:
+ * 1 - Enable physical access using DAUS.
+ * 2 - Save necessary registers
+ * 3 - Walk the page table to find the TLB entry to add (virtual to
+ * physical)
+ * 4 - Compute the TLB entry to be written (convert PTE to TLB entry)
+ * 5 - Compute the target set (0 -> 127) for the new TLB entry
+ * This is done by extracting the 6 lsb of page number
+ * 6 - Get the current way to be used which is selected using a
+ simple round robin
+ * 7 - Mark PTE entry as _PAGE_ACCESSED (and optionally PAGE_DIRTY)
+ * 8 - Commit the new tlb entry
+ * 9 - Restore the virtual memory by disabling DAUS.

Are you sure this is the result of savedefconfig? Order looks a bit odd
in several places, so I want to double check.

I believe tlb_entry is a better name and unless I've missed something, this
struct is only used internally in arch/kvx/mm, so it'd be better to declare
it in a header at arch/kvx/mm.
Generally, it's better to move internal definitions out of include/asm and
have them near the .c files that use them. For instance, I randomly picked
several functions below, e.g. kvx_mmu_probetlb(), tlb_entry_overlaps(), and
it seems they are only used in arch/kvx/mm.

There is also max_pfn that's used by various pfn walkers. In your case it
should be the same as max_low_pfn.

This may cut off the initrd memory. It's be better to cap the memory before
setting up the initrd.

This won't work because it relies on "System RAM" in the resource tree and

All occurrences of tlb_mk_entry() case paddr and vaddr parameters and then
tlb_mk_entry() essentially treats them as unsigned longs. Isn't it
better to pass declare tlb_mk_entry as

This cpu has 4 performance monitor (PM), the first one is reserved to
count cycles, and it is cycle accurate.

I didn't knew about the RDRAND insruction, but no this CPU do not have
an instruction like that.

It's a VLIW core, a bit like Itanium, there are currently not publicly
available documentation. We have started a discussion internally at
Kalray to share more information regarding this CPU and its ABI.
A very crude instruction listing can be found in our fork of
gdb-binutils: https://raw.githubusercontent.com/kalray/binutils/binutils-2_35_2/coolidge/opcodes/kv3-opc.c

Thank you for your review.
It raises questions on our side about how to handle this change.
First let me describe the hardware:
The coolidge ipi controller device handles IPI communication between cpus
inside a cluster.
Each cpu has 8 of its dedicated irq lines (24 to 31) hard-wired to the ipi.
The ipi controller has 8 sets of 2 registers:
- a 17-bit "interrupt" register
- a 17-bit "mask" register
Each couple of register is dedicated to 1 of the 8 irqlines.
Each of the 17 bits of interrupt/mask register
identifies a cpu (cores 0 to 15 + secure_core).
Writing bit i in interrupt register sends an irq to cpu i, according to the mask
in mask register.
Writing in interrupt/mask register couple N targets irq line N of the core.
- Ipi generates an interrupt to the cpu when message is ready.
- Messages are delivered via Axi.
- Ipi does not have any interrupt input lines.

with intctl = core-irq controller
We analyzed how other Linux ports are handling this situation (IPI) and here are several possible solutions:
1/ put everything in smp.c like what longarch is doing.
* Except that IPI in longarch seems to involve writing to a special purpose CPU register and not doing a memory mapped write like kvx.
2/ write a device driver in drivers/xxx/ with the content from ipi.c
* the probe would just ioremap the reg from DT and register the irq using request_percpu_irq()
* it would export a function "kvx_ipi_send()" that would directly be called by smp.c
* Question : where would this driver be placed in drivers/ ? drivers/irqchip/ ? Even if this is not per-se an interrupt-controller driver?
3/ write a "dummy" interrupt-controller driver in drivers/irqchip/:
* it would create a dummy irq_domain, ioremap the reg, request per_cpu irq
* declare a struct irq_chip with only ipi_send_mask() callback declared so that generic IPI code in kernel/irq/ipi.c (__ipi_send_single()) would work.
* This would make use of the generic IPI code like what mips and risc-v are doing.
4/ consider our "ipi device" as a mailbox and write a mailbox driver in drivers/mailbox/
5/ consider it as an msi-controller since it transforms an AXI write into IRQ. The solution would look a bit like 3/
6/ consider the ipi as "part of the core_intc" and add the content of ipi.c in drivers/irqchip/irq-kvx-core-intc.c
7/ Do like OpenRISC and CSKY:
* declare a function pointer in smp.c (see smp_cross_call() from OpenRISC https://elixir.bootlin.com/linux/latest/source/arch/openrisc/kernel/smp.c#L28)
* declare a "setter" function in smp.c (see set_send_ipi() from OpenRISC https://elixir.bootlin.com/linux/latest/source/arch/openrisc/kernel/smp.c#L202)
* write a driver in drivers/irqchip/ which ends up calling the setter function (see irq-ompic.c: https://elixir.bootlin.com/linux/latest/source/drivers/irqchip/irq-ompic.c#L191)
I would tend to exclude solution 1/ because it does not fit exactly our arch (core reg vs AXI write), or we would have to do an ioremap() from inside smp.c, is this acceptable?
I would exclude 3/ because it feels a bit dirty to hack a dummy interrupt-controller... our IPI is not an interrupt-controller, there are no input irqs. It's more like a device generating an IRQ.
4/ and 5/ feel a bit over-engineered.
6/ I guess this would work since irqchips are initialized early from init_IRQ(), but it does not reflect very much our hardware since each CPU has one core_intc but the IPI is global to each cluster and is accessed over AXI.
Having considered all of this, I would tend to end up with solution 7/ but it honestly does not feel much cleaner than our current proposition. The function pointer dance feels a bit hackish.
What would you prefer?

I am sorry, but responding with one page of hardware description is
totally unrelated to the code I am questioning here and does not make it
easier for me to respond. I understand that you want me to learn entire
new KVX architecture to be able to provide good review, but it is just
not possible, sorry. We all have quite limited time around here, so we
all expect concise and precise answers.
Best regards,
Krzysztof

This looks like it's close enough to the irqchip driver
that you can just have it in the same file as the 'intctl'
portion.
Top-level irqchip implementations tend to be rather architecture
specific, as does the IPI mechanism. Depending on the register
layout, I think you can have a single devicetree node for
the combination of the core-irq (for managing your
own interrupts) and the ipi (for receiving interrupts from
others), and then have a driver in drivers/irqchip to
deal with both. For the ipi mechanism, trying to abstract
it too much generally makes it too slow, so I would not
go through a nested irqchip or a mailbox driver etc.
I don't know what the 'apic' in your diagram is, so that
would be either a nested irqchip or could be part of
the same driver as well.
