MIPS Hardware support

MIPS Hardware support

[Thomas Bogendoerfer]

Hi,

we have 47 MIPS system types and I'd like to get an overview how alive
they really are. I've already grouped the 47 systems a little bit by
hardware I already own and regulary test kernels. Could you please
give me some feedback about the "unclassified" systems ? What systems
are supported by qemu (real test not just repeating qemu docs) ?
Thank you for your help.

Thomas.

Crap can work. Given enough thrust pigs will fly, but it's not necessarily a
good idea.                                                [ RFC1925, 2.3 ]

Here is my list:
Hardware I own and regulary boot current kernels:
- Atheros AR71XX/AR724X/AR913X based boards (ATH79)
  currently only AR9331. I do mainlining for this chip.
- MIPS Malta board (MIPS_MALTA)
  I use it as QEMU test

Both of them was recently added to our BSP:
https://git.pengutronix.de/cgit/DistroKit/commit/?id=dc788e1c1c1921321377754e47fc558558456019
https://git.pengutronix.de/cgit/DistroKit/commit/?id=521707e129e9d9039b430a201a33d45af143a6d7

Both are supported by barebox:
https://git.pengutronix.de/cgit/barebox/tree/arch/mips

Hardware I own, but not booted for a while:
Atheros AR231x/AR531x SoC support (ATH25)
Microchip PIC32 Family (MACH_PIC32)

Ingeic X1000 now boots thanks to Yanjie's effort.
I owned a board given by Yanjie, and sometimes test MIPS32 functions on it.

>LASAT Networks platforms (LASAT)
>Loongson 32-bit family of machines (MACH_LOONGSON32)
I owned a Loongson 1C board, and can confirm 5.4 is still bootable.

>Loongson-2E/F family of machines (MACH_LOONGSON2EF)
QEMU Fuloong-2E works fine, tested last year.
And I owned Fuloong-2F. Just tested 5.5 recently.

>Loongson 64-bit family of machines (MACH_LOONGSON64)
No QEMU available.
I owned a Loongson-3B1500 with RS780E PCH system. 
It works well with yesterday's mips-next.

I also have Loongson-3A4000 + 7A system,
which should belongs to this type.
However, Loongson-7A PCH support is still missing in mainline
and I'm going to work on that.

>MIPS Malta board (MIPS_MALTA)
I use QEMU Malta for regular tests.
It works smoothly.

I am using it with MIPS I6500/I6400(r6) and MIPS64R2-generic CPU
to test Debian.

Debian has some to work as build farm and porterbox.

FYI: I am successfully running 5.5 kernel on VoCore2 board (MT7628).
I had to somewhat cripple clock management to have fully working
MMC (too ashamed by that crappy code to even try to send
upstream), but it is otherwise fully working.

Re: MIPS Hardware support

[Maciej W. Rozycki]

Hi Thomas,

 My remote lab was offline until last Fri, which limited my verification 
with the latest kernels.  However I have live hardware of the following 
types and I intend to keep it up to date with Linux, and possibly still 
expand support as time permits:

> DECstations (MACH_DECSTATION)

 Several systems of different types, R3k and R4k-based.

> Loongson-2E/F family of machines (MACH_LOONGSON2EF)

 A pair of Fulong Loongson-2E machines.

> MIPS Malta board (MIPS_MALTA)

 A 5Kc-based (64-bit) Malta machine.

> Sibyte BCM91250A-SWARM (SIBYTE_SWARM)

 One system of this kind.

 I have no idea about current QEMU support, but certainly Malta used to be 
supported with various processor types.

 HTH,

  Maciej

Hi Thomas,

Here is my list (MACH_LOONGSON64):

Loongson 3A3000 CPU + AMD RS780E bridge chip
works well with the mainline kernel linux-5.6-rc3.

Loongson 3A3000 CPU + Loongson 7A1000 bridge chip
only works well with the Loongnix kernel [1]
which is an internal version of Loongson company.

Loongson 3A4000 CPU + Loongson 7A1000 bridge chip
only works well with the Loongnix kernel [1]
which is an internal version of Loongson company.

In order to support Loongson 7A1000 bridge chip,
the Loongson kernel team is working hard to refactor
the code to submit patches to the mainline kernel.

Thanks,

Tiezhu Yang

Re: MIPS Hardware support

[WANG Xuerui]

Hi Thomas,

I'm doing the occasional Linux/MIPS tinkering in my spare time, mainly
with Loongson machines. I have the following MIPS hardware:

Hardware I own and regularly boot current kernels:

- Loongson 3A3000 + RS780E development board (MACH_LOONGSON64)

This is the box I regularly rebase and test my patches with.

Hardware I own but not booted for a while:

- Lemote Yeeloong 8089D netbook (Loongson 2F, MACH_LOONGSON2EF)
- Loongson 3A2000 + RS780E development board (MACH_LOONGSON64)

These two have mainline support.

Hardware I own but not running up-to-date mainline kernels:

- OpenLoongson development board (Loongson 1C, MACH_LOONGSON32)
- Loongson Pi 2 (Loongson 2K1000 SoC, MACH_LOONGSON64)
- Loongson 3A3000 + 7A1000 development board (MACH_LOONGSON64)
- Loongson 3A4000 + 7A1000 development board (MACH_LOONGSON64)

These boards all lack mainline support. Some are in progress, like the
Modernize Loongson Machine patchset by Jiaxun that eventually leads to
mainline 7A support.

Both of my two routers happen to be MIPS-based too, with QCA9558 (ATH79)
and MT7621 (RALINK) inside respectively, but I'm unlikely to mess with
them at the moment.

Hi Thomas,

I have
- SGI Indigo2 Impact 10000 (IP28), on which I booted 4.19.79
successfully recently (after some patchwork), I am about to try out
current kernel to ask help on it (if needed)
- SGI Octane (IP30), with R12000, on which I have not tried Linux yet,
but planning to
- SGI Challange S (IP22), the same

Almost all SGI-based machines here:
  - SGI IP19/Indigo R4000 (speed unknown)
  - SGI IP22/Indy R5000 (dead RTC at the moment)
  - SGI IP26/Indigo2 R8000
  - SGI IP27/Onyx2 R14000 x4 @ 500MHz
  - SGI IP27/Origin 200 R12000 x2 @ 360MHz
  - SGI IP28/Indigo2 R10000
  - SGI IP30/Octane R14000 x2 @ 600MHz
  - SGI IP30/Octane R12000 x2 @ 400MHz
  - SGI IP32/O2 RM7000 @ 350MHz
  - SGI IP32/O2 R10000 @ 250MHz (I think)
  - SGI IP35/Fuel R14000 (I think)
  - SGI IP35/Origin 300 R14000 x4 @ 500MHz
  - SGI IP35/Tezro R16000 x4 @ 700MHz

Also have a Cobalt RaQ2 that might be salvageable, and I recently picked up
a Cobalt Qube2 that probably works (but I haven't powered it up yet).
Doubtful either of those can handle modern Linux, since their RAM is capped
at 256MB, and current gcc probably needs a lot more than that to even build.

I've enough spare parts that I can probably cobble together an RM5200-based
O2, the same CPU class as in the Cobalt devices (CPU_NEVADA), should testing
on that kind of CPU be needed (PMC Sierra-based, not NEC, so there are
differences).

I have all Alchemy DB1xxx boards, still working, as well as few MTX-1.

As an aside, does anyone know where to get "newer" MIPS hardware,
for example with 64bit MipsR6 cores?

Re: MIPS Hardware support

[dtb .]

hi
when (which kernel future release?) do you think it will be possible
to have a working PCI subsystem with SGI IP30? I'd love to use a
PCI_EHCI card, and a PCI_SATA card for a couple of practical projects.

please let me know

Loongson has 64r5 machines.
Ingenic has 32r2+ machines
elvse has 32r5 boards with P5600: http://elveesneotek.com/index.php?id=1575

> for example with 64bit MipsR6 cores?

You cannot purchase r6 machines yet.
Currently we can only use qemu:

I own and use mostly the latter (which is partially also supported by
the former), with the occasional fixes and improvements sent upstream.
BMIPS_GENERIC supports more than BCM63XX based boards, but I only have
the latter.

The long-term goal is to replace BCM63XX with BMIPS_GENERIC, but
feature parity is still a bit off.

32bit DMA support for bridge (which is needed at least for EHCI) is
on my todo list, but it's not top priority.

Hi, Thomas,

I come from Lemote Inc., the largest Loongson ODM/OEM corporation, I
have all kinds of Loongson-3 machines (with RS780, SR5690, LS2H or
LS7A bridges) and a few Loongson-2H/2K machines.

I'm working hard together with Jiaxun Yang to modernize Loongson-3's
kernel, thank you.

Thank you everybody for giving me information about your hardware.

So we have following system types without users:

LASAT Networks platforms (LASAT)
IMG Pistachio SoC based boards (MACH_PISTACHIO)
NEC EMMA2RH Mark-eins board (NEC_MARKEINS)
NEC VR4100 series based machines (MACH_VR41XX)
NXP STB220 board (NXP_STB220)
NXP 225 board (NXP_STB225)
PMC-Sierra MSP chipsets (PMC_MSP)
Toshiba TX39 series based machines (MACH_TX39XX)
Toshiba TX49 series based machines (MACH_TX49XX)
Mikrotik RB532 boards (MIKROTIK_RB532)
Cavium Networks Octeon SoC based boards (CAVIUM_OCTEON_SOC)
Netlogic XLR/XLS based systems (NLM_XLR_BOARD)
Netlogic XLP based systems (NLM_XLP_BOARD)

As you might have guessed already I'm thinking about dropping dead platforms.

Looking at git history these are my candicates for dropping in 5.8:

LASAT Networks platforms (LASAT)
NEC EMMA2RH Mark-eins board (NEC_MARKEINS)
PMC-Sierra MSP chipsets (PMC_MSP)

If there are still users of that platforms, please speak up !!!

Thomas.

We are using it for our Debian build farm, and they are quite important.

good to know, and if I haven't made it clear enough, I only want to
drop the three listed platforms below.

ath79 is well supported in OpenWrt, you can get devices in normal stores.

BRCM47xx is supported in OpenWrt, you can get devices on ebay.

I have an IMG Marduk (Creator Ci40) which uses MACH_PISTACHIO.
This is also supported in upstream OpenWrt, but it does not have many 
users.
