From: Prathap Kumar Valsan <prathap.kumar.valsan@xxxxxxxxx> On gen7 and gen7.5 devices, there could be leftover data residuals in EU/L3 from the retiring context. This patch introduces workaround to clear that residual contexts, by submitting a batch buffer with dedicated HW context to the GPU with ring allocation for each context switching. This security mitigation changes does not triggers any performance regression. Performance is on par with current drm-tips. v2: Add igt generated header file for CB kernel assembled with Mesa tool and addressed use of Kernel macro for ptr_align comment. v3: Resolve Sparse warnings with newly generated, and imported CB kernel. v4: Include new igt generated CB kernel for gen7 and gen7.5. Also add code formatting and compiler warnings changes (Chris Wilson) Signed-off-by: Mika Kuoppala <mika.kuoppala@xxxxxxxxxxxxxxx> Signed-off-by: Prathap Kumar Valsan <prathap.kumar.valsan@xxxxxxxxx> Signed-off-by: Akeem G Abodunrin <akeem.g.abodunrin@xxxxxxxxx> Cc: Chris Wilson <chris.p.wilson@xxxxxxxxx> Cc: Balestrieri Francesco <francesco.balestrieri@xxxxxxxxx> Cc: Bloomfield Jon <jon.bloomfield@xxxxxxxxx> Cc: Dutt Sudeep <sudeep.dutt@xxxxxxxxx> Acked-by: Chris Wilson <chris.p.wilson@xxxxxxxxx> Link: https://patchwork.freedesktop.org/patch/msgid/20200304130353.2448417-2-chris@xxxxxxxxxxxxxxxxxx --- drivers/gpu/drm/i915/Makefile | 1 + drivers/gpu/drm/i915/gt/gen7_renderclear.c | 402 ++++++++++++++++++ drivers/gpu/drm/i915/gt/gen7_renderclear.h | 15 + drivers/gpu/drm/i915/gt/hsw_clear_kernel.c | 61 +++ drivers/gpu/drm/i915/gt/intel_gpu_commands.h | 17 +- .../gpu/drm/i915/gt/intel_ring_submission.c | 3 +- drivers/gpu/drm/i915/gt/ivb_clear_kernel.c | 61 +++ 7 files changed, 556 insertions(+), 4 deletions(-) create mode 100644 drivers/gpu/drm/i915/gt/gen7_renderclear.c create mode 100644 drivers/gpu/drm/i915/gt/gen7_renderclear.h create mode 100644 drivers/gpu/drm/i915/gt/hsw_clear_kernel.c create mode 100644 drivers/gpu/drm/i915/gt/ivb_clear_kernel.c diff --git a/drivers/gpu/drm/i915/Makefile b/drivers/gpu/drm/i915/Makefile index 991a8c537d12..9f887a86e555 100644 --- a/drivers/gpu/drm/i915/Makefile +++ b/drivers/gpu/drm/i915/Makefile @@ -80,6 +80,7 @@ gt-y += \ gt/debugfs_gt.o \ gt/debugfs_gt_pm.o \ gt/gen6_ppgtt.o \ + gt/gen7_renderclear.o \ gt/gen8_ppgtt.o \ gt/intel_breadcrumbs.o \ gt/intel_context.o \ diff --git a/drivers/gpu/drm/i915/gt/gen7_renderclear.c b/drivers/gpu/drm/i915/gt/gen7_renderclear.c new file mode 100644 index 000000000000..de595b66a746 --- /dev/null +++ b/drivers/gpu/drm/i915/gt/gen7_renderclear.c @@ -0,0 +1,402 @@ +// SPDX-License-Identifier: MIT +/* + * Copyright © 2019 Intel Corporation + */ + +#include "gen7_renderclear.h" +#include "i915_drv.h" +#include "intel_gpu_commands.h" + +#define MAX_URB_ENTRIES 64 +#define STATE_SIZE (4 * 1024) +#define GT3_INLINE_DATA_DELAYS 0x1E00 +#define batch_advance(Y, CS) GEM_BUG_ON((Y)->end != (CS)) + +struct cb_kernel { + const void *data;
