From 7a8a3430be15e4e6b3455f71853e7db765323889 Mon Sep 17 00:00:00 2001 From: Timothy Pearson Date: Sat, 7 Dec 2019 16:48:09 -0600 Subject: [PATCH] amdgpu: Wrap FPU dependent functions in dc20 dc20 containes several FPU-dependent functions without proper FPU kernel mode enable/disable wrappers. Add the required wrappers for both x86 and POWER. This enables Navi DC20 support for POWER systems. v2: fix compilation Signed-off-by: Timothy Pearson Signed-off-by: Alex Deucher --- .../gpu/drm/amd/display/dc/dcn20/dcn20_resource.c | 20 ++++++++++++++++---- 1 file changed, 16 insertions(+), 4 deletions(-) diff --git a/drivers/gpu/drm/amd/display/dc/dcn20/dcn20_resource.c b/drivers/gpu/drm/amd/display/dc/dcn20/dcn20_resource.c index 1e8b79b708a5..47adcd4555ec 100644 --- a/drivers/gpu/drm/amd/display/dc/dcn20/dcn20_resource.c +++ b/drivers/gpu/drm/amd/display/dc/dcn20/dcn20_resource.c @@ -2887,12 +2887,19 @@ bool dcn20_validate_bandwidth(struct dc *dc, struct dc_state *context, bool voltage_supported = false; bool full_pstate_supported = false; bool dummy_pstate_supported = false; - double p_state_latency_us = context->bw_ctx.dml.soc.dram_clock_change_latency_us; - context->bw_ctx.dml.soc.disable_dram_clock_change_vactive_support = dc->debug.disable_dram_clock_change_vactive_support; + double p_state_latency_us; - if (fast_validate) - return dcn20_validate_bandwidth_internal(dc, context, true); + DC_FP_START(); + p_state_latency_us = context->bw_ctx.dml.soc.dram_clock_change_latency_us; + context->bw_ctx.dml.soc.disable_dram_clock_change_vactive_support = + dc->debug.disable_dram_clock_change_vactive_support; + if (fast_validate) { + voltage_supported = dcn20_validate_bandwidth_internal(dc, context, true); + + DC_FP_END(); + return voltage_supported; + } // Best case, we support full UCLK switch latency voltage_supported = dcn20_validate_bandwidth_internal(dc, context, false); @@ -2921,6 +2928,7 @@ bool dcn20_validate_bandwidth(struct dc *dc, struct dc_state *context, restore_dml_state: context->bw_ctx.dml.soc.dram_clock_change_latency_us = p_state_latency_us; + DC_FP_END(); return voltage_supported; } @@ -3442,6 +3450,8 @@ static bool dcn20_resource_construct( enum dml_project dml_project_version = get_dml_project_version(ctx->asic_id.hw_internal_rev); + DC_FP_START(); + ctx->dc_bios->regs = &bios_regs; pool->base.funcs = &dcn20_res_pool_funcs; @@ -3739,10 +3749,12 @@ static bool dcn20_resource_construct( pool->base.oem_device = NULL; } + DC_FP_END(); return true; create_fail: + DC_FP_END(); dcn20_resource_destruct(pool); return false; -- 2.11.0
