* sparc: Add lazy floating point switchSebastian Huber2017-07-256-219/+136
| | | | | | | | | | | | | | | | | | | | | | | | | | | | The SPARC ABI is a bit special with respect to the floating point context. The complete floating point context is volatile. Thus, from an ABI point of view nothing needs to be saved and restored during a context switch. Instead the floating point context must be saved and restored during interrupt processing. Historically, the deferred floating point switch was used for SPARC and the complete floating point context is saved and restored during a context switch to the new floating point unit owner. This is a bit dangerous since post-switch actions (e.g. signal handlers) and context switch extensions may silently corrupt the floating point context. The floating point unit is disabled for interrupt handlers. Thus, in case an interrupt handler uses the floating point unit then this will result in a trap (INTERNAL_ERROR_ILLEGAL_USE_OF_FLOATING_POINT_UNIT). In uniprocessor configurations, a lazy floating point context switch is used. In case an active floating point thread is interrupted (PSR[EF] == 1) and a thread dispatch is carried out, then this thread is registered as the floating point owner. When a floating point owner is present during a context switch, the floating point unit is disabled for the heir thread (PSR[EF] == 0). The floating point disabled trap checks that the use of the floating point unit is allowed and saves/restores the floating point context on demand. Update #3077.

* sparc: Add assembly workaround for LEON3FT B2BST errataDaniel Cederman2017-07-173-0/+33
| | | | | | | | | | | | | | | This patch adds NOP instructions to prevent instruction sequences that are sensitive to the LEON3FT B2BST errata. See GRLIB-TN-0009: "LEON3FT Stale Cache Entry After Store with Data Tag Parity Error" for more information. The sequences are only modified if __FIX_LEON3FT_B2BST is defined. The patch works in conjunction with the -mfix-ut700, -mfix-gr712rc, and -mfix-ut699 GCC flags that prevents the sensitive sequences from being generated. Update #3057.

* arm: Fix ARMv7-M interrupt processingSebastian Huber2017-07-042-30/+48
| | | | | | | | | | | | Right after a "msr basepri_max, %[basepri]" instruction an interrupt service may still take place (observed at least on Cortex-M7). However, pendable service calls that are activated during this interrupt service may be delayed until interrupts are enable again. The _ARMV7M_Pendable_service_call() did not check that a thread dispatch is allowed. Move this test from _ARMV7M_Interrupt_service_leave() to _ARMV7M_Pendable_service_call(). Update #3060.
