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.

2017-03-24external: Update xscom utils for type 1 indirect accessesMichael Neuling3-6/+27
Update get/putscom utils to support type 1 indirect access. Currently we do some (ugly) bit mangling so that we can fit a 64 bit scom address into the debugfs interface. The current code only shifts down the top bit (indirect bit). This patch changes it to shift down the whole top nibble so that the form of the indirection is also shifted. Also currently putscom always reads back the value. This causes a problem for form 1 which can only be written. This patch marks the form 1 as not readable and hence doesn't attempt the read back. The kernel debugfs scom driver doesn't do the bit mangling correctly. So for form1 to work correctly, the kernel debugfs scom driver needs updating. Existing scoms are forwards and backwards compatible with the kernel. (FWIW the kernel PRD scom interface doesn't need to be updated as it passes the whole 64 bit scom address without any bit mangling) Signed-off-by: Michael Neuling <mikey@neuling.org> Reviewed-by: Cédric Le Goater <clg@kaod.org> Signed-off-by: Stewart Smith <stewart@linux.vnet.ibm.com>

Secondly, if it was using GARD_VERSION it produced a broken tarball that still looked into the skiboot source for files despite them having been copied into the tarball. Lastly (and not really a make dist issue) the current way of symlinking make_version.sh was racey.

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.

2016-12-21arch_flash_arm: Don't assume mtd labels are shortJoel Stanley1-1/+1
pflash relies on arch_flash_arm parsing /proc/mtd to discover the pnor partition. It helpfully uses strcasestr so it can handle the string changing, which is what has happened as we moved to upstream compliant mtd device tree bindings. We currently have a string like this: dev: size erasesize name mtd0: 00060000 00001000 "u-boot" mtd1: 00020000 00001000 "u-boot-env" mtd2: 00280000 00001000 "kernel" mtd3: 001c0000 00001000 "initramfs" mtd4: 01740000 00001000 "rofs" mtd5: 00400000 00001000 "rwfs" mtd6: 02000000 00001000 "1e620000.flash-controller:flash@1" mtd7: 08000000 00001000 "1e630000.flash-controller:pnor@0" Unfortunately arch_flash_arm assumes the string will be at most 50 characters. That's right before the label we're looking for starts so we ignore that line and keep searching. Fix it by allowing for a 255 character line.

This can be seen by when checking the output of "Mapping range" in the kernel log: # dmesg |grep "Mapping range" Mapping range 0x0 - 0x100000000 with 0x40000000 Without this patch, the kernel will use 64K (0x10000) instead: # dmesg |grep "Mapping range" Mapping range 0x0 - 0x100000000 with 0x10000 Signed-off-by: Chris Smart <chris@distroguy.com> Acked-by: Michael Neuling <mikey@neuling.org> Signed-off-by: Stewart Smith <stewart@linux.vnet.ibm.com>

Warnings in progress.c are not critical but warn about %d being used in printf format string when the parameter passed is unsigned. Trivial fixup which should silence the warnings. Signed-off-by: Cyril Bur <cyril.bur@au1.ibm.com> Signed-off-by: Stewart Smith <stewart@linux.vnet.ibm.com>
2016-10-11v2 mambo: Add section for kernel command line boot argsChris Smart1-0/+4
Users can set kernel command line boot arguments for Mambo in a tcl script. This adds a place holder at the bottom of the skiboot.tcl script so that users know what format to use.

2016-10-10external/boot_tests: remove lid from the BMC after flashingClaudio Carvalho1-2/+10
Usually, BMC systems doesn't have too much space for storage. This removes the lid from the BMC after the lid is flashed. Signed-off-by: Claudio Carvalho <cclaudio@linux.vnet.ibm.com> Signed-off-by: Stewart Smith <stewart@linux.vnet.ibm.com>
2016-10-10external/boot_tests: add the nobooting option -NClaudio Carvalho1-10/+21
This adds the -N option for BMC targets, which does not boot the firmware. The option helps in situations that we need to flash multiple partitions before booting the firmware. Signed-off-by: Claudio Carvalho <cclaudio@linux.vnet.ibm.com> Signed-off-by: Stewart Smith <stewart@linux.vnet.ibm.com>
2016-10-10external/boot_tests: add arbitrary lid option -FClaudio Carvalho2-3/+27
There are situations where we want to flash a lid that isn't neither BOOTKERNEL nor PAYLOAD. That's the case for CAPP, to test secure and trusted boot patches we need to flash CAPP with different secure boot headers. This adds the -F option for BMC targets that can be used to flash an arbitrary lid. Example: '-F CAPP:cappucode.bin.sec.ecc' will flash CAPP partition with cappucode.bin.sec.ecc The eyecatch for each partition is defined in https://github/open-power/pnor.git Signed-off-by: Claudio Carvalho <cclaudio@linux.vnet.ibm.com> Signed-off-by: Stewart Smith <stewart@linux.vnet.ibm.com>
2016-09-26occ/prd/opal-prd: Queue OCC_RESET event message to host in OpenPOWERShilpasri G Bhat1-0/+6
During an OCC reset cycle the system is forced to Psafe pstate. When OCC becomes active, the system has to be restored to its last pstate as requested by host. So host needs to be notified of OCC_RESET event or else system will continue to remian in Psafe state until host requests a new pstate after the OCC reset cycle. This patch defines 'OPAL_PRD_MSG_TYPE_OCC_RESET_NOTIFY' to notify OPAL when opal-prd issues OCC reset. OPAL will queue OCC_RESET message to host when it receives opal_prd_msg of type '*_OCC_RESET_NOTIFY'.
