From: Piotr Piorkowski Date: Tue, 5 Jun 2018 15:13:29 +0000 (+0200) Subject: drm/i915/guc: Move defines with size of GuC logs to intel_guc_log.h X-Git-Tag: Ubuntu-5.2.0-15.16~3798^2~35^2~76 X-Git-Url: https://git.proxmox.com/?a=commitdiff_plain;h=5288c7182dd389bb03b0a1aa38550b344fe5bf97;p=mirror_ubuntu-eoan-kernel.git drm/i915/guc: Move defines with size of GuC logs to intel_guc_log.h At this moment, we have defined GuC logs sizes in intel_guc_fwif.h, but as these values are related directly to the GuC logs, and not to API of GuC parameters, we should move these defines to intel_guc_log.h. v2: - change buffers size to more friendly (Michał Wajdeczko) - remove GUC_LOG_SIZE define (Michał Wajdeczko) v3: - use SZ_* macros to define buffers sizes (Michał Wajdeczko) Signed-off-by: Piotr Piórkowski Cc: Michal Wajdeczko Cc: Michał Winiarski Cc: Joonas Lahtinen Cc: Chris Wilson Reviewed-by: Michal Wajdeczko Signed-off-by: Chris Wilson Link: https://patchwork.freedesktop.org/patch/msgid/20180605151330.9954-1-piotr.piorkowski@intel.com --- diff --git a/drivers/gpu/drm/i915/intel_guc.c b/drivers/gpu/drm/i915/intel_guc.c index dce475eaa39b..4101264cf566 100644 --- a/drivers/gpu/drm/i915/intel_guc.c +++ b/drivers/gpu/drm/i915/intel_guc.c @@ -263,13 +263,31 @@ static u32 guc_ctl_log_params_flags(struct intel_guc *guc) u32 offset = intel_guc_ggtt_offset(guc, guc->log.vma) >> PAGE_SHIFT; u32 flags; - /* each allocated unit is a page */ - flags = GUC_LOG_VALID | GUC_LOG_NOTIFY_ON_HALF_FULL | - (GUC_LOG_CRASH_PAGES << GUC_LOG_CRASH_SHIFT) | - (GUC_LOG_DPC_PAGES << GUC_LOG_DPC_SHIFT) | - (GUC_LOG_ISR_PAGES << GUC_LOG_ISR_SHIFT) | + #define UNIT SZ_4K + + BUILD_BUG_ON(!CRASH_BUFFER_SIZE); + BUILD_BUG_ON(!IS_ALIGNED(CRASH_BUFFER_SIZE, UNIT)); + BUILD_BUG_ON(!DPC_BUFFER_SIZE); + BUILD_BUG_ON(!IS_ALIGNED(DPC_BUFFER_SIZE, UNIT)); + BUILD_BUG_ON(!ISR_BUFFER_SIZE); + BUILD_BUG_ON(!IS_ALIGNED(ISR_BUFFER_SIZE, UNIT)); + + BUILD_BUG_ON((CRASH_BUFFER_SIZE / UNIT - 1) > + (GUC_LOG_CRASH_MASK >> GUC_LOG_CRASH_SHIFT)); + BUILD_BUG_ON((DPC_BUFFER_SIZE / UNIT - 1) > + (GUC_LOG_DPC_MASK >> GUC_LOG_DPC_SHIFT)); + BUILD_BUG_ON((ISR_BUFFER_SIZE / UNIT - 1) > + (GUC_LOG_ISR_MASK >> GUC_LOG_ISR_SHIFT)); + + flags = GUC_LOG_VALID | + GUC_LOG_NOTIFY_ON_HALF_FULL | + ((CRASH_BUFFER_SIZE / UNIT - 1) << GUC_LOG_CRASH_SHIFT) | + ((DPC_BUFFER_SIZE / UNIT - 1) << GUC_LOG_DPC_SHIFT) | + ((ISR_BUFFER_SIZE / UNIT - 1) << GUC_LOG_ISR_SHIFT) | (offset << GUC_LOG_BUF_ADDR_SHIFT); + #undef UNIT + return flags; } diff --git a/drivers/gpu/drm/i915/intel_guc_fwif.h b/drivers/gpu/drm/i915/intel_guc_fwif.h index 0867ba76d445..1a0f2a39cef9 100644 --- a/drivers/gpu/drm/i915/intel_guc_fwif.h +++ b/drivers/gpu/drm/i915/intel_guc_fwif.h @@ -84,12 +84,12 @@ #define GUC_LOG_VALID (1 << 0) #define GUC_LOG_NOTIFY_ON_HALF_FULL (1 << 1) #define GUC_LOG_ALLOC_IN_MEGABYTE (1 << 3) -#define GUC_LOG_CRASH_PAGES 1 #define GUC_LOG_CRASH_SHIFT 4 -#define GUC_LOG_DPC_PAGES 7 +#define GUC_LOG_CRASH_MASK (0x1 << GUC_LOG_CRASH_SHIFT) #define GUC_LOG_DPC_SHIFT 6 -#define GUC_LOG_ISR_PAGES 7 +#define GUC_LOG_DPC_MASK (0x7 << GUC_LOG_DPC_SHIFT) #define GUC_LOG_ISR_SHIFT 9 +#define GUC_LOG_ISR_MASK (0x7 << GUC_LOG_ISR_SHIFT) #define GUC_LOG_BUF_ADDR_SHIFT 12 #define GUC_CTL_PAGE_FAULT_CONTROL 5 @@ -532,20 +532,6 @@ enum guc_log_buffer_type { }; /** - * DOC: GuC Log buffer Layout - * - * Page0 +-------------------------------+ - * | ISR state header (32 bytes) | - * | DPC state header | - * | Crash dump state header | - * Page1 +-------------------------------+ - * | ISR logs | - * Page9 +-------------------------------+ - * | DPC logs | - * Page17 +-------------------------------+ - * | Crash Dump logs | - * +-------------------------------+ - * * Below state structure is used for coordination of retrieval of GuC firmware * logs.
