[Why] irq service requires changes for DCE6 support [How] (v1) DCE6 targets are added replicating existing DCE8 implementation. due to missing CRTC_VERTICAL_INTERRUPT0_CONTROL registers/masks, dce/dce_8_0_{d,sh_mask}.h used instead of dce/dce_6_0_{d,sh_mask}.h (v2) DCE6 headers used adding the necessary vblank irq registers (INT_MASK and VBLANK_STATUS) and vblank irq masks as implemented in amdgpu driver. Add vblank_irq_info_funcs_dce60 with .set and .ack as per commit b10d51f ("drm/amd/display: Add interrupt entries for VBLANK isr.") and use it in vblank_int_entry(reg_num) macro definition (v3) updated due to following kernel 5.3 commit: 4fc4dca ("drm/amd: drop use of drmp.h in os_types.h") (v4) updated due to following kernel 5.6 commit: d9e3267 ("drm/amd/display: cleanup of construct and destruct funcs") Signed-off-by: Mauro Rossi <issor.oruam@xxxxxxxxx> --- drivers/gpu/drm/amd/display/dc/irq/Makefile | 11 + .../display/dc/irq/dce60/irq_service_dce60.c | 395 ++++++++++++++++++ .../display/dc/irq/dce60/irq_service_dce60.h | 40 ++ .../gpu/drm/amd/display/dc/irq/irq_service.c | 3 + 4 files changed, 449 insertions(+) create mode 100644 drivers/gpu/drm/amd/display/dc/irq/dce60/irq_service_dce60.c create mode 100644 drivers/gpu/drm/amd/display/dc/irq/dce60/irq_service_dce60.h diff --git a/drivers/gpu/drm/amd/display/dc/irq/Makefile b/drivers/gpu/drm/amd/display/dc/irq/Makefile index 3352b79fb1cb..405c25322607 100644 --- a/drivers/gpu/drm/amd/display/dc/irq/Makefile +++ b/drivers/gpu/drm/amd/display/dc/irq/Makefile @@ -30,6 +30,17 @@ AMD_DAL_IRQ = $(addprefix $(AMDDALPATH)/dc/irq/,$(IRQ)) AMD_DISPLAY_FILES += $(AMD_DAL_IRQ) +############################################################################### +# DCE 6x +############################################################################### +ifdef CONFIG_DRM_AMD_DC_SI +IRQ_DCE60 = irq_service_dce60.o + +AMD_DAL_IRQ_DCE60 = $(addprefix $(AMDDALPATH)/dc/irq/dce60/,$(IRQ_DCE60)) + +AMD_DISPLAY_FILES += $(AMD_DAL_IRQ_DCE60) +endif + ############################################################################### # DCE 8x ############################################################################### diff --git a/drivers/gpu/drm/amd/display/dc/irq/dce60/irq_service_dce60.c b/drivers/gpu/drm/amd/display/dc/irq/dce60/irq_service_dce60.c new file mode 100644 index 000000000000..524481885fd0 --- /dev/null +++ b/drivers/gpu/drm/amd/display/dc/irq/dce60/irq_service_dce60.c @@ -0,0 +1,395 @@ +/* + * Copyright 2020 Mauro Rossi <issor.oruam@xxxxxxxxx> + * + * Permission is hereby granted, free of charge, to any person obtaining a + * copy of this software and associated documentation files (the "Software"), + * to deal in the Software without restriction, including without limitation + * the rights to use, copy, modify, merge, publish, distribute, sublicense, + * and/or sell copies of the Software, and to permit persons to whom the + * Software is furnished to do so, subject to the following conditions: + * + * The above copyright notice and this permission notice shall be included in + * all copies or substantial portions of the Software. + * + * THE SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY KIND, EXPRESS OR + * IMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF MERCHANTABILITY, + * FITNESS FOR A PARTICULAR PURPOSE AND NONINFRINGEMENT.
