Instead, each IP block (graphics, media, display) will have their own architecture major.minor versions and stepping ID's which should be read directly from a register in the MMIO space. New hardware programming styles, features, and workarounds should be conditional solely on the architecture version, and should no longer be derived from the PCI device ID, revision ID, or platform-specific feature flags. v1.1: Fix build error Bspec: 63361, 64111 Signed-off-by: Matt Roper Signed-off-by: Rodrigo Vivi Signed-off-by: Radhakrishna Sripada --- drivers/gpu/drm/i915/gt/intel_gt_regs.h | 2 + drivers/gpu/drm/i915/i915_driver.c | 80 ++++++++++++++++++- drivers/gpu/drm/i915/i915_drv.h | 16 ++-- drivers/gpu/drm/i915/i915_pci.c | 1 + drivers/gpu/drm/i915/i915_reg.h | 6 ++ drivers/gpu/drm/i915/intel_device_info.c | 32 ++++---- drivers/gpu/drm/i915/intel_device_info.h | 14 ++++ .../gpu/drm/i915/selftests/mock_gem_device.c | 1 + 8 files changed, 128 insertions(+), 24 deletions(-) diff --git a/drivers/gpu/drm/i915/gt/intel_gt_regs.h b/drivers/gpu/drm/i915/gt/intel_gt_regs.h index 94f9ddcfb3a5..a053493dae24 100644 --- a/drivers/gpu/drm/i915/gt/intel_gt_regs.h +++ b/drivers/gpu/drm/i915/gt/intel_gt_regs.h @@ -39,6 +39,8 @@ #define FORCEWAKE_ACK_RENDER_GEN9 _MMIO(0xd84) #define FORCEWAKE_ACK_MEDIA_GEN9 _MMIO(0xd88) +#define GMD_ID_GRAPHICS _MMIO(0xd8c) + #define MCFG_MCR_SELECTOR _MMIO(0xfd0) #define SF_MCR_SELECTOR _MMIO(0xfd8) #define GEN8_MCR_SELECTOR _MMIO(0xfdc) diff --git a/drivers/gpu/drm/i915/i915_driver.c b/drivers/gpu/drm/i915/i915_driver.c index deb8a8b76965..33566f6e9546 100644 --- a/drivers/gpu/drm/i915/i915_driver.c +++ b/drivers/gpu/drm/i915/i915_driver.c @@ -70,6 +70,7 @@ #include "gem/i915_gem_pm.h" #include "gt/intel_gt.h" #include "gt/intel_gt_pm.h" +#include "gt/intel_gt_regs.h" #include "gt/intel_rc6.h" #include "pxp/intel_pxp_pm.h" @@ -306,15 +307,83 @@ static void sanitize_gpu(struct drm_i915_private *i915) __intel_gt_reset(to_gt(i915), ALL_ENGINES); } +#define IP_VER_READ(offset, ri_prefix) \ + addr = pci_iomap_range(pdev, 0, offset, sizeof(u32)); \ + if (drm_WARN_ON(&i915->drm, !addr)) { \ + /* Fall back to whatever was in the device info */ \ + RUNTIME_INFO(i915)->ri_prefix.ver = INTEL_INFO(i915)->ri_prefix.ver; \ + RUNTIME_INFO(i915)->ri_prefix.rel = INTEL_INFO(i915)->ri_prefix.rel; \ + goto ri_prefix##done; \ + } \ + \ + ver = ioread32(addr); \ + pci_iounmap(pdev, addr); \ + \ + RUNTIME_INFO(i915)->ri_prefix.ver = REG_FIELD_GET(GMD_ID_ARCH_MASK, ver); \ + RUNTIME_INFO(i915)->ri_prefix.rel = REG_FIELD_GET(GMD_ID_RELEASE_MASK, ver); \ + RUNTIME_INFO(i915)->ri_prefix.step = REG_FIELD_GET(GMD_ID_STEP, ver); \ + \ + /* Sanity check against expected versions from device info */ \ + if (RUNTIME_INFO(i915)->ri_prefix.ver != INTEL_INFO(i915)->ri_prefix.ver || \ + RUNTIME_INFO(i915)->ri_prefix.rel > INTEL_INFO(i915)->ri_prefix.rel) \ + drm_dbg(&i915->drm, \ + "Hardware reports " #ri_prefix " IP version %u.%u but minimum expected is %u.%u\n", \ + RUNTIME_INFO(i915)->ri_prefix.ver, \ + RUNTIME_INFO(i915)->ri_prefix.rel, \ + INTEL_INFO(i915)->ri_prefix.ver, \ + INTEL_INFO(i915)->ri_prefix.rel); \ +ri_prefix##done: + +/** + * intel_ipver_early_init - setup IP version values + * @dev_priv: device private + * + * Setup the graphics version for the current device.

One platform could have { arch = 12, rel = 70, step = 1 } and the actual stepping is STEP_B0 but without the translation of the step field would mean STEP_A1. That is why we will need to have gmd_to_intel_step tables for each IP.
