2015-06-18Set proper value for RPR registerskiboot-5.0.4Benjamin Herrenschmidt1-0/+3
The value was provided by Dave Larson and is what pHyp uses Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org> Signed-off-by: Stewart Smith <stewart@linux.vnet.ibm.com>
2015-04-01Move contents of opal.h to opal-api.hMichael Ellerman1-1/+1
Move the contents of opal.h, which is the definition of the OPAL API shared with Linux, into opal-api.h. Recreate opal.h, containing just the include of types.h as well as including opal-api.h and opal-internal.h. We can also remove the #ifdef SKIBOOT, because opal.h is no longer shared with Linux. This gets us to an opal-api.h that is purely a superset of Linux's opal-api.h, ie. the only differences are things that are new in skiboot and haven't yet been added to Linux. Finally update head.S to only include opal-api.h, which is all it needs, and avoids the need for ASSEMBLY guards in opal.h.

2015-03-31exceptions: Remove deprecated exception patching stuffBenjamin Herrenschmidt1-125/+0
Linux no longer calls it, it never worked on LE and generally speaking never really did anything useful anyway. Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org> Signed-off-by: Stewart Smith <stewart@linux.vnet.ibm.com>

2014-11-22opal: Remove MCE handling code.Mahesh Salgaonkar1-5/+0
Removed following: - Machine check handle and other related routines. - per-cpu MCE event used to record machine check data cpu_thread->mc_event; - Machine check related definition including mce event structure from include/opal.h - A comment above GET_STACK() #define that warns about runtime modification made to GET_STACK macro by MC patching code.

2014-11-17Stack checking extensionsBenjamin Herrenschmidt1-1/+7
This patch adds: - Normal builds are done with -fstack-protector (we want to investigate using -fstack-protector-strong on gcc4.9 but for now we just use that - Build with STACK_CHECK=1 will use -fstack-protector-all and -pg and will check the stack in mcount Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org>
2014-10-24irq/occ/opal: Add self-sent dummy interruptBenjamin Herrenschmidt1-0/+3
This makes OPAL use the OCC interrupt facility to send itself an interrupt whenever the OPAL event bit is set as a result of an OPAL call that wasn't itself opal_handle_interrupt() or opal_handle_hmi() (both of which we know the OS will already deal with appropriately). This ensures that OPAL event changes are notified to Linux via its interrupt path which is necessary for it to properly broadcast the state change to its various clients.
