AST2700 wdt controller is similiar to AST2600's wdt, but
the AST2700 has 8 watchdogs, and they each have 0x80 of registers.
Introduce ast2700 object class and increase the number of regs(offset) of
ast2700 model.

The SDRAM memory controller(DRAMC) controls the access to external
DDR4 and DDR5 SDRAM and power up to DDR4 and DDR5 PHY.
The DRAM memory controller of AST2700 is not backward compatible
to previous chips such AST2600, AST2500 and AST2400.
Max memory is now 8GiB on the AST2700. Introduce new
aspeed_2700_sdmc and class with read/write operation and
reset handlers.
Define DRAMC necessary protected registers and
unprotected registers for AST2700 and increase

If you both okay, I will remove it.
Do I need to create a new patch or just update in this patch?

I don't think this is necessary to do so now. Possibly, increase the
version number in the vmstate when resending a v5.
Also, all Aspeed models should be addressed and that's beyond the scope
of this series.

If I understand your request, do you mean to change as following in this patch?
static const VMStateDescription vmstate_aspeed_sdmc = {
.name = "aspeed.sdmc",
.version_id = 1, ---> Change 2
.minimum_version_id = 1, ---> Change 2
};
> Also, all Aspeed models should be addressed and that's beyond the scope of
> this series.
>
And create a new patch series to update all vmstate version for all ASPEED models?
Take asoeed_gpio.c for example:
static const VMStateDescription vmstate_gpio_regs = {
.name = TYPE_ASPEED_GPIO"/regs",
.version_id = 1, ---> Change 2
.minimum_version_id = 1, ---> Change --> 2
}

That would be to remove migration support for Aspeed machines. For later.
Let's address AST2700 first.

DMA length is from 1 byte to 32MB for AST2600 and AST10x0
and DMA length is from 4 bytes to 32MB for AST2500.
In other words, if "R_DMA_LEN" is 0, it should move at least 1 byte
data for AST2600 and AST10x0 and 4 bytes data for AST2500.
To support all ASPEED SOCs, adds dma_start_length parameter to store
the start length, add helper routines function to compute the dma length
and update DMA_LENGTH mask to "1FFFFFF" to support dma 1 byte
length unit for AST2600 and AST1030.
Currently, only supports dma length 4 bytes aligned.

AST2700 support the maximum dram size is 8GiB
and has a "DMA DRAM Side Address High Part(0x7C)"
register to support 64 bits dma dram address.
Add helper routines functions to compute the dma dram
address, new features and update trace-event
to support 64 bits dram address.

Here s->dram_base is 0x0. Do we really need to check
aspeed_smc_has_dma64?
> + }
Maybe simplify improving aspeed_smc_dma_dram_addr() as:
static uint64_t aspeed_smc_dma_dram_addr(AspeedSMCState *s)
{
return (s->regs[R_DMA_DRAM_ADDR]
| ((uint64_t) s->regs[R_DMA_DRAM_ADDR_HIGH] << 32))
- s->dram_base;
}
Then no need for dma_dram_offset, dma_dram_addr is enough.

Yes, it is required to check aspeed_smc_has_dma64 to support dram 64bit address.
s->dram_base has been changed to "0x4 00000000".

You are right, it could be done as your proposal below. However,
we should add a comment regarding some values :
R_DMA_DRAM_ADDR_HIGH and s->dram_base are only set on the AST2700
SoC and zero on other Aspeed SoCs.

we need both, dma_dram_offset for the transaction and dma_dram_addr
to update the R_DMA_DRAM_ADDR_HIGH reg. A bit cumbersome, I agree.

AST2700 fmc/spi controller's address decoding unit is 64KB
and only bits [31:16] are used for decoding. Introduce seg_to_reg
and reg_to_seg handlers for ast2700 fmc/spi controller.
In addition, adds ast2700 fmc, spi0, spi1, and spi2 class init handler.

Is this a bugfix? If so, please use a separate patch. Otherwise
please mention why it is OK to widen access for AST2600 & AST10x0.

Ah I missed that. I wonder how we could set different access width
tough on the model ?
Should we allocate a MemoryRegionOps in the realize() handler and set
the width depending on the SoC ?

According the design of SPI drivers, it uses this "memcpy_fromio" KERNEL API for SPI calibration.
https://github.com/AspeedTech-BMC/linux/blob/1062a07420f9aed4ed7dc9deb3429b8e7828f5cf/drivers/spi/spi-aspeed-smc.c#L1832
AST2700 is a 64 bits quad core cpus(Cortex-a35), so kernel API use 64 bits for data access.
https://github.com/AspeedTech-BMC/linux/blob/aspeed-master-v6.6/arch/arm64/kernel/io.c#L25
I simply set the max_access_size to 8 for AST2700 support.
AST2500, AST2600 and AST10x0 are all 32bits CPUS, that was why this max_access_size 8 did not impact these models.
https://github.com/AspeedTech-BMC/linux/blob/aspeed-master-v6.6/arch/arm/kernel/io.c#L45
If you have any suggestion about this patch modification, please let me know.
I am going to re-send v5 patch for AST2700 support.

Yes. I think we are safe on that side.

Please move this change in its own commit explaining the reason and
add a TODO comment in the code.
The aspeed_smc_flash_ops MemoryRegionOps should be copied in _realize()
to set a different width for the AST2700 SoC. You could do that too.
Thanks,
C.

I will do the following changes. Could you give me any suggestion?
1. add asc->max_access_size = 8 in aspeed_2700_fmc_class_init, aspeed_2700_spi0_class_init, aspeed_2700_spi1_class_init and aspeed_2700_spi2_class_init
2. Update aspeed_smc_flash_realize as below
static void aspeed_smc_flash_realize(DeviceState *dev, Error **errp)
{
------
s->asc = ASPEED_SMC_GET_CLASS(s->controller)
if (s->asc->max_access_size ==8) --> check max_access_size
aspeed_smc_flash_ops.valid.max_access_size = s->asc->max_access --> update max_access_size
/*
* Use the default segment value to size the memory region. This
* can be changed by FW at runtime.
*/
memory_region_init_io(&s->mmio, OBJECT(s), &aspeed_smc_flash_ops,
s, name, s->asc->segments[s->cs].size);
------
}

You can not because aspeed_smc_flash_ops is a static const shared
by all models
Best option is to introduce a new 'const MemoryRegionOps*' attribute
in AspeedSMCClass and use it in aspeed_smc_flash_realize().

AST2700 have two SCU controllers which are SCU and SCUIO.
Both SCU and SCUIO registers are not compatible previous SOCs
, introduces new registers and adds ast2700 scu, sucio class init handler.
The pclk divider selection of SCUIO is defined in SCUIO280[20:18] and
the pclk divider selection of SCU is defined in SCU280[25:23].
Both of them are not compatible AST2600 SOCs, adds a get_apb_freq function
and trace-event for AST2700 SCU and SCUIO.

AST2700 interrupt controller(INTC) provides hardware interrupt interfaces
to interrupt of processors PSP, SSP and TSP. In INTC, each interrupt of
INT 128 to INT136 combines 32 interrupts.
Introduce a new aspeed_intc class with instance_init and realize handlers.
So far, this model only supports GICINT128 to GICINT136.
It creates 9 GICINT or-gates to connect 32 interrupts sources
from GICINT128 to GICINT136 as IRQ GPIO-OUTPUT pins.
Then, this model registers IRQ handler with its IRQ GPIO-INPUT pins which
connect to GICINT or-gates. And creates 9 GICINT IRQ GPIO-OUTPUT pins which
connect to GIC device with GIC IRQ 128 to 136.
If one interrupt source from GICINT128 to GICINT136
set irq, the OR-GATE irq callback function is called and set irq to INTC by
OR-GATE GPIO-OUTPUT pins. Then, the INTC irq callback function is called and
set irq to GIC by its GICINT IRQ GPIO-OUTPUT pins. Finally, the GIC irq
callback function is called and set irq to CPUs and
CPUs execute Interrupt Service Routine (ISR).

I would add an assert on aic->num_ints to make sure it is not greater
than ASPEED_INTC_NR_INTS.

I am considering to support INTC model for future BMC SOCs.
For example, if the num_ints has been changed to "18" in the future BMC Socs, users only need to update ASPEED_INTC_NR_INTS and
Create a aspeed_XXXX_intc_class_init to set its "aic->num_ints 18".
That was why I set aic->num_ints 9 in aspeed_2700_intc_class_init.
Thanks for your review and suggestion.

OK. This is minor.

Initial definitions for a simple machine using an AST2700 SOC (Cortex-a35 CPU).
AST2700 SOC and its interrupt controller are too complex to handle
in the common Aspeed SoC framework. We introduce a new ast2700
class with instance_init and realize handlers.
AST2700 is a 64 bits quad core cpus and support 8 watchdog.
Update maximum ASPEED_CPUS_NUM to 4 and ASPEED_WDTS_NUM to 8.
In addition, update AspeedSocState to support scuio, sli, sliio and intc.
Add TYPE_ASPEED27X0_SOC machine type.
The SDMC controller is unlocked at SPL stage.
At present, only supports to emulate booting
start from u-boot stage. Set SDMC controller
unlocked by default.
In INTC, each interrupt of INT 128 to INT 136 combines 32 interrupts.
It connect GICINT IRQ GPIO-OUTPUT pins to GIC device with irq 128 to 136.
And, if a device irq is 128 to 136, its irq GPIO-OUTPUT pin is connected to
GICINT or-gates instead of GIC device.

I would find clearer to initialize/realize the underlying gic object
under the AspeedINTCState model. You could add property aliases.
or
add a GICv3State gic object under the SoC. Probably better, since the
AspeedINTCState doesn't need to know about the GIC.

Please change that to :
arm_ss.add(when: ['CONFIG_ASPEED_SOC', 'TARGET_AARCH64'], if_true: files('aspeed_ast27x0.c'))
The AST2700 SoC model uses aarch64 CPUs.

Thanks review and suggestion.
I refer to versal_create_apu_gic function, https://github.com/qemu/qemu/blob/master/hw/arm/xlnx-versal.c#L67
and updated aspeed_soc_ast2700_gic as following.
If you have any concerned about the new changes, please let me know.
Thanks-Jamin

Could we avoid qemu_get_cpu() and use the cpu array of the SoC instead ?

Yes, I can change it and my new changes as following.
DeviceState *cpudev = DEVICE(&a->cpu[i]);
Will fix in v5 patch.

AST2700 CPU is ARM Cortex-A35 which is 64 bits.
Add TARGET_AARCH64 to build this machine.
According to the design of ast2700, it has a bootmcu(riscv-32) which
is used for executing SPL.
Then, CPUs(cortex-a35) execute u-boot, kernel and rofs.
Currently, qemu not support emulate two CPU architectures
at the same machine. Therefore, qemu will only support
to emulate CPU(cortex-a35) side for ast2700

AST2700 dram size calculation is not back compatible AST2600.
According to the DDR capacity hardware behavior,
if users write the data to address which is beyond the ram size,
it would write the data to address 0.
For example:
a. sdram base address "0x4 00000000"
b. sdram size is 1 GiB
The available address range is from "0x4 00000000" to "0x4 40000000".
If users write 0xdeadbeef to address "0x6 00000000",
the value of DRAM address 0 (base address 0x4 00000000) should be 0xdeadbeef.
Add aspeed_soc_ast2700_dram_init to calculate the dram size and add
memory I/O whose address range is from max_ram_size - ram_size to max_ram_size
and its read/write handler to emulate DDR capacity hardware behavior.

I would simplify with write transaction on the DRAM memory region
of the SoC.
For that, initialize a 'dram_as' on top of 'dram_mr' in
aspeed_soc_ast2700_dram_init():
address_space_init(&s->dram_as, s->dram_mr, "dram");
Then, in aspeed_ram_capacity_write(), add :
address_space_write(&s->dram_as, addr % ram_size, MEMTXATTRS_UNSPECIFIED,
&data, size);
and check returned error.
It should be enough to detect the RAM size from FW.
Thanks,
C.

Thanks for your suggestion and review.
I changed to use address space APIs to write DRAM memory region(s->dram_mr).
I have a question about aspeed_ram_capacity_write function implementation.
Could you tell me which solution you prefer? Do you want to use solution 1?
Thanks-Jamin
Solution 1:
static void aspeed_ram_capacity_write(void *opaque, hwaddr addr, uint64_t data,
unsigned int size)
{
AspeedSoCState *s = ASPEED_SOC(opaque);
ram_addr_t ram_size;
MemTxResult result;
ram_size = object_property_get_uint(OBJECT(&s->sdmc), "ram-size",
&error_abort);
/*
* Emulate ddr capacity hardware behavior.
* If writes the data to the address which is beyond the ram size,
* it would write the data to the "address % ram_size".
*/
result = address_space_write(&s->dram_as, addr % ram_size,
MEMTXATTRS_UNSPECIFIED, &data, 4);
if (result != MEMTX_OK) {
qemu_log_mask(LOG_GUEST_ERROR,
"%s: DRAM write failed, addr:0x%" HWADDR_PRIx
", data :0x%" PRIx64 "\n",
__func__, addr % ram_size, data);
}
}
We don't care the test pattern. If users write the data to the invalid address, the date will be written into the DRAM memory region at "addr % dram_size".
Ex: dram size is 1G and the available address range is from "0x4 00000000" to "0x4 3FFFFFFF"
Users write data(0x12345678) at invalid address "0x5 00000000" and the data would be written at address "0x4 00000000"
=> md 400000000 1
400000000: dbeef432
=> mw 500000000 12345678
=> md 400000000 1
400000000: 12345678
Solution 2:
static void aspeed_ram_capacity_write(void *opaque, hwaddr addr, uint64_t data,
unsigned int size)
{
AspeedSoCState *s = ASPEED_SOC(opaque);
uint32_t test_pattern = 0xdeadbeef;
bool invalid_pattern = true;
ram_addr_t ram_size;
MemTxResult result;
int sz;
ram_size = object_property_get_uint(OBJECT(&s->sdmc), "ram-size",
&error_abort);
/*
* Emulate ddr capacity hardware behavior.
* If writes the test_pattern to the address which is beyond the ram size,
* it would write the test_pattern to the "address % ram_size".
*/
for (sz = 4; sz > 0 ; sz--) {
test_pattern = (test_pattern << 4) + sz;
if (data == test_pattern) {
result = address_space_write(&s->dram_as, addr % ram_size,
MEMTXATTRS_UNSPECIFIED, &data, 4);
if (result != MEMTX_OK) {
qemu_log_mask(LOG_GUEST_ERROR,
"%s: DRAM write failed, pattern:0x%" PRIx64

}
}
It check test patterns. If users write the invalid test pattern to the invalid address, the date will NOT be written into the DRAM memory region at "addr % dram_size".
Ex: dram size is 1G and the available address range is from "0x4 00000000" to "0x4 3FFFFFFF"
Users write invalid test pattern (0x12345678) at invalid address "0x5 00000000" and the data would not be written at address "0x4 00000000"
Invalid test pattern
=> md 400000000 1
400000000: dbeef432
=> mw 500000000 12345678
=> md 400000000 1
400000000: dbeef432
Only valid pattern would be written at address "0x4 00000000"
Pattern --> (0xdeadbeef << 4) + 4
=> md 400000000 1
400000000: dbeef432
=> mw 500000000 deadbeef4
=> md 400000000 1
400000000: eadbeef4

I prefer solution 1 because no assumption is made on what software does.
It simply implements the wraparound HW does on RAM accesses.

Add a test case to test Aspeed OpenBMC SDK v09.01 on AST2700 board.
It loads u-boot-nodtb.bin, u-boot.dtb, tfa and optee-os
images to dram first which base address is 0x400000000.
Then, boot and launch 4 cpu cores.
```
qemu-system-aarch64 -machine ast2700-evb
-device loader,force-raw=on,addr=0x400000000,file=workdir/u-boot-nodtb.bin \
-device loader,force-raw=on,addr=uboot_dtb_load_addr,file=workdir/u-boot.dtb\
-device loader,force-raw=on,addr=0x430000000,file=workdir/bl31.bin\
-device loader,force-raw=on,addr=0x430080000,file=workdir/optee/tee-raw.bin\
-device loader,cpu-num=0,addr=0x430000000 \
-device loader,cpu-num=1,addr=0x430000000 \
-device loader,cpu-num=2,addr=0x430000000 \
-device loader,cpu-num=3,addr=0x430000000 \
-smp 4 \
-drive file=workdir/image-bmc,format=raw,if=mtd
```

Jamin,
I think you should add your self as a Reviewer to the ASPEED BMCs
machine in the MAINTAINERS files. Would you agree ?
Thanks,

You should send a patch updating the MAINTAINERS file with new names
and those promoted should reply that they agree, or not.
See https://qemu.readthedocs.io/en/v9.0.0/devel/maintainers.html for
more info and the git history of MAINTAINERS also.
