[PATCH 00/10] ARM64 / ACPI: Prototype for cpu hot-plug

by Hanjun Guo

Here is the first version of prototype for cpu-hotplug on ARM64. The first part is patch 1~3 for MADT parse. MADT is being parsed and the cpu possible map and cpu present map are prefilled. I kept the terminology consistent with x86 as Al and Andrea's advice. CPU possible map is equal to the GIC entries in MADT no matter enabled or disabled, and cpu present map limits to the enabled cpu in MADT. This is the base for cpu hot-plug. The second part is patch 4~10 for ACPI cpu hot-plug drivers. ACPI driver for CPU hot-plug is implemented in this part, when the cpu logical online/offline is ready, the cpu hot-plug can work on arm64. Please give some comments, thanks.

Hi Hanjun and others, I have rebased these patches on the 3.10rcX based tree and done a quick boot test and they don't cause any oopses. So I thought I would push them to the tree. Thanks Graeme

[RFC][PATCH 0/3] Prototype cpu topology and cpu-hotplug (part1: parse MADT)

by Hanjun Guo

Here is the first part of cpu topology and cpu-hotplug code for RFC. In this part of code, MADT is being parsed and the cpu possible map and cpu present map are prefilled. CPU possible map is equal to the GIC entries in MADT no matter enabled or disabled, and cpu present map limits to the enabled cpu in MADT. Without this patch set, CPU possible map is equal to the cpus found in FDT, and cpu possible map is the same as cpu present map with no hotplugble cpus. Boot information with this patch (with --cores=4): ACPI: GIC (acpi_id[0x0000] gic_id[0x0000] enabled) // MADT was parsed ACPI: GIC (acpi_id[0x0001] gic_id[0x0001] enabled) ACPI: GIC (acpi_id[0x0002] gic_id[0x0002] disabled) ACPI: GIC (acpi_id[0x0003] gic_id[0x0003] disabled) ACPI: GIC (acpi_id[0x0004] gic_id[0x0004] disabled) ACPI: GIC (acpi_id[0x0005] gic_id[0x0005] disabled) ACPI: GIC (acpi_id[0x0006] gic_id[0x0006] disabled) ACPI: GIC (acpi_id[0x0007] gic_id[0x0007] disabled) 2 CPUs available, 8 CPUs total //find 2 enabled cpus which // is the same as MADT described ACPI: GIC Distributor (id[0x0000] address[0x2c001000] gsi_base[0]) // IOAPIC(GIC distributor is also parsed) Using ACPI (MADT) for SMP configuration information SMP: limits to 4 CPUs // the foundation model supports only 4 four cpus SMP: Allowing 4 CPUs, 2 hotplug CPUs // so limits to 4 cpus, and 2 disabled in MADT can be hotpluged PERCPU: Embedded 10 pages/cpu @ffffffc03ffa7000 s11520 r8192 d21248 u40960 [....] CPU1: Booted secondary processor Brought up 2 CPUs SMP: Total of 2 processors activated (400.00 BogoMIPS). Because only 2 cpus is enabled in MADT, so the system will up 2 cpus in despite of --cores=4. Next step will prototype cpu topology code for ACPI driver. This is the RFC version only, will updated and rebased on the new acpi branch.

ACPI/ACPI-combined switch 10AM BST 27th June

by Graeme Gregory

Hi Guys, Discussed this with Al and I think everyone is finished with 3.9 work now! I am going to switch the acpi branch to be the contents of the acpi-combined branch at 10AM tomorrow my local time! The two branches will initially be :- acpi - our work branch now based off 3.10-rcX kernel (and will track mainline releases/rc releases) acpi-ltfixes - is the acpi branch + some needed fixes from Samsung landing team for Arndale prototyping. We can of course create more short term branches for demos, prototyping as needed. Thanks Graeme

acpi-combined & network/LPAE fixes for Arndale

by Graeme Gregory

Hi guys, I have extracted the necessary fixes from Samsung Landing Team tree for Arndale network (actually usb hack) and LPAE. I have uploaded these on top of our acpi-combined branch as acpi-combined-ltfixes. This should make it easier for people testing armv7. I have attached my config file for this. Thanks Graeme

ACPI Table Size Issue

by Graeme Gregory

Hi, I have managed to boot our ACPI enabled kernel on the beaglebone device which has working earlyprintk. You will see from the log below there is a very familiar looking RCU stall, same place as I was seeing with Hanjun's patches. I did not check the size of his blob but I suspect its the same issue and actually not to do with cpu topology at all. Anyway below is the log of the ACPI kernel booting on the beaglebone.

[PATCH] ARM: ACPI: remove 64bit divide replace with do_div

From: Graeme Gregory <graeme.gregory(a)linaro.org> I some situations custom 64bit by 32bit divide was giving the wrong values so replace it with the internal kernel do_div function instead.

RAS and ACPI

by Tomasz Nowicki

Hi Robert, I am doing APEI implementation of ACPI specification. That is, ACPI kernel side of RAS work. I am manage to test some of APEI functionality now. I would like to ask about status of LEG-389 since I want to avoid of doing work that may be actually already done. Regards, Tomasz Nowicki

example GPIO ASL

by Al Stone

Sorry I did not send this out sooner -- I rewrote it a several different times over the last week to play with some ideas... Nonetheless, here's the simple bit of ASL I'm using for GPIO right now: Scope (\_SB) { // Base Address: 0x11400000 Device (GPA0) // GPIO controller GPA0 { Name (_HID, "LINA0002") Name (_UID, 0x00) Method (_CRS, 0x0, Serialized) { Name(RBUF, ResourceTemplate () { Memory32Fixed (ReadWrite, 0x11400000, 0x18) GpioIo (Exclusive, PullDefault, , // debounce timeout , // drive strength , // IO restriction "GPA0") { // pin numbers 0x00, 0x01, 0x02, 0x03, 0x04, 0x05, 0x06, 0x07 } }) Return(RBUF) } } } This is still not quite working in the Samsung gpiolib code just yet. They never really used FDT before (or at least, not in a way I would consider proper) so I'm having to unwind some partial movement to FDT and their specific data structures. GPIO interrupts are not going to be much different but I don't have a good example to send out just yet. You should be able to figure out the address from the current FDT. The pin numbers are much better hidden in mach-exynos/include/mach/gpio.h. Sometimes it's easier just to read them from /sys :). I put this in an SSDT just for grins, but it can also go in the DSDT. -- ciao, al ----------------------------------- Al Stone Software Engineer Linaro Enterprise Group al.stone(a)linaro.org -----------------------------------

Combined armv7/armv8 3.10-rc6 kernel

by Graeme Gregory

Hi Everyone, I have combined our work on armv7 and armv8 into one branch based on 3.10rc6 mainline kernel. This is newer than our previous base which was 3.9 based. This kernel boots on both of our main test platforms 1) Arndale 2) armv8 Foundation Model The branch is available here. https://git.linaro.org/gitweb?p=arm/acpi/acpi.git;a=shortlog;h=refs/heads/a… I have attached to the email the two configs I used. I would suggest that we use this is a base for ongoing work so its easy to switch between model and hardware for tests. Thanks Graeme

Upstreaming Session

by Graeme Gregory

Hi, I think the upstreaming session I was talking about at standup is this one. http://lce-13.zerista.com/event/member/81058 I suggest that even though this clashes with hacking sessions most of the team should go to this to prevent Greg KH using you as an example at future connects. For those who were not at last connect here is the video of Gregs talk https://www.youtube.com/watch?v=iiED1K98lnw Thanks Graeme

[PATCH 00/14] armv8 ACPI bringup

by Graeme Gregory

Hi Guys, I have just pushed this series of patches to the official repo. Branch is acpi-armv8 This brings us to the same state in armv8 as we are in for armv7. Without the prototype stuff like i2c drivers. But is a base to start work on for armv8. I have tried to get these patches as checkpatch clean as possible. I want to try and merge armv7 and armv8 changes into one and maintain that together as I think there is very little different in the two platforms from the point of initialisation or drivers. Thanks Graeme

[PATCHv2] ACPI state

by Graeme Gregory

Hi, I have managed to get us to boot as far as the dreaded > ACPI: Interpreter enabled state on armv8 now. For now ACPI tables cannot be bigger than 1MB in size (we are nowhere near this size). And also FDT cannot be bigger than 1MB (still nowhere near). >From the conversion which was mostly changing u32 -> void * u32 -> phys_addr_t and adding the correct initialisation to the setup.c on armv8 it is becoming clear that with the correct universal types used that the arch/arm/kernel/acpi and arch/arm64/kernel/acpi are actually mostly generic to both platforms so we will need to decide where to put them. This genericness is nice to have as it means we should be able to switch v7/v8 at will for testing! There is still some code from armv7 that I have not yet brought over to v8 and someone fluent in v8 assembler needs to fix the two assembly bits. I shall continue to bring code over and enable more ACPI features. Graeme
