2017-09-04mambo: Add mambo socket programMichael Neuling2-0/+367
This adds a program that can be run inside a mambo simulator in linux userspace which enables TCP sockets to be proxied in and out of the simulator to the host. Unlike mambo bogusnet, it's requires no linux or skiboot specific drivers/infrastructure to run. eg. Run inside the simulator: - to forward host ssh connections to sim ssh server ./mambo-socket-proxy -h 10022 -s 22 Then connect to port 10022 on your host ssh -p 10022 localhost - to allow http proxy access from inside the sim to local http proxy ./mambo-socket-proxy -b proxy.mynetwork -h 3128 -s 3128 Multiple connections are supported.

2017-06-19mambo: Update P9 PVR to reflect Scale out 24 core chipsMichael Neuling1-2/+2
The P9 PVR bits 48:51 don't indicate a revision but instead different configurations. From BookIV we have: Bits: Configuration 0: Scale out 12 cores 1: Scale out 24 cores 2: Scale up 12 cores 3: Scale up 24 cores Skiboot will mostly the use "Scale out 24 core" configuration (ie. SMT4 not SMT8) so reflect this in mambo. Signed-off-by: Michael Neuling <mikey@neuling.org> Signed-off-by: Stewart Smith <stewart@linux.vnet.ibm.com>
2017-06-14mambo: Create multiple chips when we have multiple CPUsMichael Ellerman1-1/+11
Currently when we boot mambo with multiple CPUs, we create multiple CPU nodes in the device tree, and each claims to be on a separate chip. However we don't create multiple xscom nodes, which means skiboot only knows about a single chip, and all CPUs end up on it. At the moment mambo is not able to create multiple xscom controllers. We can create fake ones, just by faking the device tree up, but that seems uglier than this solution. So create a mambo-chip for each CPU other than 0, to tell skiboot we want a separate chip created. This then enables Linux to see multiple chips: smp: Brought up 2 nodes, 2 CPUs numa: Node 0 CPUs: 0 numa: Node 1 CPUs: 1 Signed-off-by: Michael Ellerman <mpe@ellerman.id.au> Signed-off-by: Stewart Smith <stewart@linux.vnet.ibm.com>

2017-06-08mambo: Add a reservation for the initramfsOliver O'Halloran1-0/+5
On most systems the initramfs is loaded inside the part of memory reserved for the OS [0x0-0x30000000] and skiboot will never touch it. On mambo it's loaded at 0x80000000 and if you're unlucky skiboot can allocate over the top of it and corrupt the initramfs blob. There might be the downside that the kernel cannot re-use the initramfs memory since it's marked as reserved, but the kernel might also free it anyway.

2017-06-06mambo: Match whole string when looking up symbols with linsym/skisymMichael Ellerman1-2/+2
linsym/skisym use a regex to match the symbol name, and accepts a partial match against the entry in the symbol map, which can lead to somewhat confusing results, eg: systemsim % linsym early_setup 0xc000000000027890 systemsim % linsym early_setup$ 0xc000000000aa8054 systemsim % linsym early_setup_secondary 0xc000000000027890 I don't think that's the behaviour we want, so append a $ to the name so that the symbol has to match against the whole entry, eg: systemsim % linsym early_setup 0xc000000000aa8054 Signed-off-by: Michael Ellerman <mpe@ellerman.id.au> Tested-by: Oliver O'Halloran <oohall@gmail.com> Signed-off-by: Stewart Smith <stewart@linux.vnet.ibm.com>
2017-05-31mambo: Allow loading multiple CPIOsMichael Ellerman1-4/+10
Currently we have support for loading a single CPIO and telling Linux to use it as the initrd. But the Linux code actually supports having multiple CPIOs contiguously in memory, between initrd-start and end, and will unpack them all in order. That is a really nice feature as it means you can have a base CPIO with your root filesystem, and then tack on others as you need for various tests etc. So expand the logic to handle SKIBOOT_INITRD, and treat it as a comma separated list of CPIOs to load. I chose comma as it's fairly rare in filenames, but we could make it space, colon, whatever. Or we could add a new environment variable entirely. The code also supports trimming whitespace from the values, so you can have "cpio1, cpio2".

2017-05-19mambo: Add skiboot/linux symbol lookupOliver O'Halloran2-0/+50
Adds the skisym and linsym commands which can be used to find the address of a Linux or Skiboot symbol. To function this requires the user to provide the SKIBOOT_MAP and VMLINUX_MAP environmental variables which indicate which skiboot.map and System.map files should be used. Examples: Look up a symbol address: systemsim % skisym .load_and_boot_kernel 0x0000000030013a08 Set a breakpoint there: systemsim % b [skisym .load_and_boot_kernel] breakpoint set at [0:0]: 0x0000000030013a08 (0x0000000030013A08) Enc:0x7D800026 : mfcr r12 Signed-off-by: Oliver O'Halloran <oohall@gmail.com> Signed-off-by: Stewart Smith <stewart@linux.vnet.ibm.com>
2017-05-03mambo: Fix reserved-ranges nodeOliver O'Halloran1-0/+4
The DT bindings for the /reserved-memory node requires that it: a) Has #size-cells equal to the root b) Has #address-cells equal to the root c) Has an empty ranges property (i.e directly maps on the root) Currently we do not assign any of these when generating the Mambo device tree which causes the booted kernel to ignore the reservations in the /reserved-memory node.

2017-05-01external/mambo: add helper for machine checksNicholas Piggin1-3/+187
Add helpers to construct machine checks with registers set up properly. exc_mce raises a machine check exception that can be stepped into. This is useful for testing the machine check handler. Also add a similar exc_sreset for system reset. inject_mce does the same but runs immediately and stops when the instruction reaches the NIP (which can get tangled up if machine check re-enters this code). This is useful for testing robustness to interleaving machine checks. inject_mce_step allows injecting MCEs between each instruction and stepping over them. inject_mce_step_ri does the same but only when MSR has RI set. This can be useful to test correctness of low level code. For example, testing system call vs machine check: systemsim % b 0xC000000000004c00 systemsim % c 0xC000000000004C00 (0x0000000000004C00) Enc:0xA64BB17D : mtspr HSPRG1,r13 systemsim % inject_mce_step_ri 100 0xC000000000004C04 (0x0000000000004C04) Enc:0xA64AB07D : mfspr r13,HSPRG0 0xC000000000004C08 (0x0000000000004C08) Enc:0x80002DF9 : std r9,0x80(r13) 0xC000000000004C0C (0x0000000000004C0C) Enc:0xA6E2207D : mfspr r9,PPR 0xC000000000004C10 (0x0000000000004C10) Enc:0x7813427C : mr r2,r2 0xC000000000004C14 (0x0000000000004C14) Enc:0x88004DF9 : std r10,0x88(r13) 0xC000000000004C18 (0x0000000000004C18) Enc:0xD8002DF9 : std r9,0xD8(r13) 0xC000000000004C1C (0x0000000000004C1C) Enc:0x2600207D : mfcr r9 0xC000000000004C20 (0x0000000000004C20) Enc:0xE8074D89 : lbz r10,0x7E8(r13) 0xC000000000004C24 (0x0000000000004C24) Enc:0x00000A2C : cmpwi cr0,r10,0 0xC000000000004C28 (0x0000000000004C28) Enc:0xA80F8240 : bne cr0,$+0xFA8 (bc 0x4,0x2,0xFA8,0,0) 0xC000000000004C2C (0x0000000000004C2C) Enc:0xA64AB17D : mfspr r13,HSPRG1 0xC000000000004C30 (0x0000000000004C30) Enc:0xBE1E202C : cmpdi cr0,r0,7870 0xC000000000004C34 (0x0000000000004C34) Enc:0x2000C241 : beq cr0,$+0x20 (bc 0xE,0x2,0x20,0,0) 0xC000000000004C38 (0x0000000000004C38) Enc:0x786BA97D : mr r9,r13 0xC000000000004C3C (0x0000000000004C3C) Enc:0xA64AB07D : mfspr r13,HSPRG0 0xC000000000004C40 (0x0000000000004C40) Enc:0xA6027A7D : mfspr r11,SRR0 0xC000000000004C44 (0x0000000000004C44) Enc:0xA6029B7D : mfspr r12,SRR1 0xC000000000004C48 (0x0000000000004C48) Enc:0x02004039 : li r10,2 0xC000000000004C4C (0x0000000000004C4C) Enc:0x6401417D : mtmsrd r10,1 0xC000000000004C50 (0x0000000000004C50) Enc:0xB0620048 : b $+0x62B0 236380163: (212143620): Disabling lock debugging due to kernel taint 0xC000000000004C50 (0x0000000000004C50) Enc:0xB0620048 : b $+0x62B0 0xC00000000000AF00 (0x000000000000AF00) Enc:0xE1F78A79 : rldicl. r10,r12,30,63,63 (0x0000000000000001) 0xC00000000000AF00 (0x000000000000AF00) Enc:0xE1F78A79 : rldicl. r10,r12,30,63,63 (0x0000000000000001) [...] Every instruction after 0xC000000000004C4C is getting an interleaving MCE, and continuing after this injection the kernel prints a lot of MCE reports and continues working properly.

Currently the "p" command uses puts to output the result to the user. This works for interactive usage, but it makes it impossible for use inside scripts. This patch changes the function to return the value rather than print it. The mambo interpreter prints the result of an expression so this should not cause any user visible changes.

Only make PVR change when running on the POWER8 simulator. Signed-off-by: Michael Neuling <mikey@neuling.org> Signed-off-by: Stewart Smith <stewart@linux.vnet.ibm.com>
2015-10-21mambo: Use SIMHOST to determine the simulator typeMichael Neuling1-2/+4
Use SIMHOST to determine the simulator type. This means we can support past and future sims other than P8. Signed-off-by: Michael Neuling <mikey@neuling.org> [stewart@linux.vnet.ibm.com: support environments without SIMHOST] Signed-off-by: Stewart Smith <stewart@linux.vnet.ibm.com>

2015-08-21external/mambo: Update PVR valueSamuel Mendoza-Jonas1-0/+1
Running little-endian kernels in mambo requires HILE to be set properly, which requires a bump in the machine's pvr value to a DD2.x chip.

2015-05-25Refactor mambo test runningStewart Smith1-2/+0
we now properly control the simulation rather than just killing off Mambo. For boot test, we wait for petitboot and actually shut down the simulation properly with 'halt'. Signed-off-by: Stewart Smith <stewart@linux.vnet.ibm.com>
2015-03-31mambo: Make mambo_utils.tcl optionalMichael Ellerman1-5/+8
Only source mambo_utils.tcl if we can find it. This allows using skiboot.tcl from another directory, which is useful for automated testing. We need to open code the body of "ton" and "c" obviously, in case we didn't find skiboot.tcl.

2015-03-31mambo: Exit mambo when the simulation is stoppedMichael Ellerman1-2/+1
When the simulation runs to completion, exit mambo. In addition to the previous patch this allows "halt" on the Linux command line to stop the simulation and exit mambo. Note that this only takes effect if the "mysim go" is left to run until the simulation is stopped. If the user interrupts the simulation, eg. with Ctrl-C, to inspect state, then the exit has no effect.
