GICINT192_201 = maps 1:10 to input IRQ 0 and output IRQs 0 to 9. Each status bit corresponds to a specific IRQ. Implemented "aspeed_intc_set_irq_handler_multi_outpins" to handle IRQs with multiple output pins. Introduced "aspeed_intc_status_handler_multi_outpins" for managing status registers associated with multi-output IRQs. Added new IRQ definitions for GICINT192_201 in INTC. Adjusted the IRQ array to accommodate 10 input pins and 19 output pins, aligning with the new GICINT192_201 mappings. |------------------------------| | INTC | |inpin[0:0]--------->outpin[0] | |inpin[0:1]--------->outpin[1] | |inpin[0:2]--------->outpin[2] | |inpin[0:3]--------->outpin[3] | orgates[0]-------> |inpin[0:4]--------->outpin[4] | |inpin[0:5]--------->outpin[5] | |inpin[0:6]--------->outpin[6] | |inpin[0:7]--------->outpin[7] | |inpin[0:8]--------->outpin[8] | |inpin[0:9]--------->outpin[9] | | | orgates[1]------> |inpin[1]----------->outpin[10]| orgates[2]------> |inpin[2]----------->outpin[11]| orgates[3]------> |inpin[3]----------->outpin[12]| orgates[4]------> |inpin[4]----------->outpin[13]| orgates[5]------> |inpin[5]----------->outpin[14]| orgates[6]------> |inpin[6]----------->outpin[15]| orgates[7]------> |inpin[7]----------->outpin[16]| orgates[8]------> |inpin[8]----------->outpin[17]| orgates[9]------> |inpin[9]----------->outpin[18]| |------------------------------| Signed-off-by: Jamin Lin Reviewed-by: C=C3=A9dric Le Goater --- include/hw/intc/aspeed_intc.h | 4 +- hw/intc/aspeed_intc.c | 149 ++++++++++++++++++++++++++++++---- hw/intc/trace-events | 1 + 3 files changed, 137 insertions(+), 17 deletions(-) diff --git a/include/hw/intc/aspeed_intc.h b/include/hw/intc/aspeed_intc.h index e6c3a27264..85df8c6be9 100644 --- a/include/hw/intc/aspeed_intc.h +++ b/include/hw/intc/aspeed_intc.h @@ -16,8 +16,8 @@ #define TYPE_ASPEED_2700_INTC TYPE_ASPEED_INTC "-ast2700" OBJECT_DECLARE_TYPE(AspeedINTCState, AspeedINTCClass, ASPEED_INTC) =20 -#define ASPEED_INTC_MAX_INPINS 9 -#define ASPEED_INTC_MAX_OUTPINS 9 +#define ASPEED_INTC_MAX_INPINS 10 +#define ASPEED_INTC_MAX_OUTPINS 19 =20 typedef struct AspeedINTCIRQ { int inpin_idx; diff --git a/hw/intc/aspeed_intc.c b/hw/intc/aspeed_intc.c index 3aa97add8b..f2ca9237ea 100644 --- a/hw/intc/aspeed_intc.c +++ b/hw/intc/aspeed_intc.c @@ -39,6 +39,8 @@ REG32(GICINT135_EN, 0x700) REG32(GICINT135_STATUS, 0x704) REG32(GICINT136_EN, 0x800) REG32(GICINT136_STATUS, 0x804) +REG32(GICINT192_201_EN, 0xB00) +REG32(GICINT192_201_STATUS, 0xB04) =20 static const AspeedINTCIRQ *aspeed_intc_get_irq(AspeedINTCClass *aic, uint32_t reg) @@ -112,9 +114,55 @@ static void aspeed_intc_set_irq_handler(AspeedINTCStat= e *s, } } =20 +static void aspeed_intc_set_irq_handler_multi_outpins(AspeedINTCState *s, + const AspeedINTCIRQ *intc_irq, uint32_t s= elect) +{ + const char *name =3D object_get_typename(OBJECT(s)); + uint32_t status_reg; + int num_outpins; + int outpin_idx; + int inpin_idx; + int i; + + num_outpins =3D intc_irq->num_outpins; + status_reg =3D intc_irq->status_reg; + outpin_idx =3D intc_irq->outpin_idx; + inpin_idx =3D intc_irq->inpin_idx; + + for (i =3D 0; i < num_outpins; i++) { + if (select & BIT(i)) { + if (s->mask[inpin_idx] & BIT(i) || + s->regs[status_reg] & BIT(i)) { + /* + * a. mask bit is not 0 means in ISR mode sources interrupt + * routine are executing. + * b. status bit is not 0 means previous source interrupt + * does not be executed, yet. + * + * save source interrupt to pending bit. + */ + s->pending[inpin_idx] |=3D BIT(i); + trace_aspeed_intc_pending_irq(name, inpin_idx, + s->pending[inpin_idx]); + } else { + /* + * notify firmware which source interrupt are coming + * by setting status bit + */ + s->regs[status_reg] |=3D BIT(i); + trace_aspeed_intc_trigger_irq(name, inpin_idx, outpin_idx = + i, + s->regs[status_reg]); + aspeed_intc_update(s, inpin_idx, outpin_idx + i, 1); + } + } + } +} + /* - * GICINT128 to GICINT136 map 1:1 to input and output IRQs 0 to 8. - * The value of input IRQ should be between 0 and the number of inputs. + * GICINT192_201 maps 1:10 to input IRQ 0 and output IRQs 0 to 9. + * GICINT128 to GICINT136 map 1:1 to input IRQs 1 to 9 and output + * IRQs 10 to 18.
