From caf3038123d6d29afd7d1f0cd6db98a2282c3ca1 Mon Sep 17 00:00:00 2001 From: Eric Anholt Date: Mon, 26 Oct 2009 09:28:32 -0700 Subject: [PATCH] Make a convenient int for what chipset generation we're on. gen2/3/4 are easier to say than "8xx, 915-945/g33/pineview, 965/g45/misc", and compares on generation are often easier than stringing together a bunch of chipset checks. --- src/mesa/drivers/dri/intel/intel_context.c | 17 ++++++++++++----- src/mesa/drivers/dri/intel/intel_context.h | 5 +++++ src/mesa/drivers/dri/intel/intel_mipmap_tree.c | 2 +- src/mesa/drivers/dri/intel/intel_regions.c | 3 +-- src/mesa/drivers/dri/intel/intel_tex_validate.c | 2 +- 5 files changed, 20 insertions(+), 9 deletions(-) diff --git a/src/mesa/drivers/dri/intel/intel_context.c b/src/mesa/drivers/dri/intel/intel_context.c index a7d94ced9a9..e0022ad5481 100644 --- a/src/mesa/drivers/dri/intel/intel_context.c +++ b/src/mesa/drivers/dri/intel/intel_context.c @@ -477,7 +477,7 @@ intel_flush(GLcontext *ctx, GLboolean needs_mi_flush) if (intel->Fallback) _swrast_flush(ctx); - if (!IS_965(intel->intelScreen->deviceID)) + if (intel->gen < 4) INTEL_FIREVERTICES(intel); /* Emit a flush so that any frontbuffer rendering that might have occurred @@ -614,6 +614,13 @@ intelInitContext(struct intel_context *intel, intel->sarea = intelScreen->sarea; intel->driContext = driContextPriv; + if (IS_965(intel->intelScreen->deviceID)) + intel->gen = 4; + else if (IS_9XX(intel->intelScreen->deviceID)) + intel->gen = 3; + else + intel->gen = 2; + /* Dri stuff */ intel->hHWContext = driContextPriv->hHWContext; intel->driFd = sPriv->fd; @@ -621,7 +628,7 @@ intelInitContext(struct intel_context *intel, driParseConfigFiles(&intel->optionCache, &intelScreen->optionCache, intel->driScreen->myNum, - IS_965(intelScreen->deviceID) ?
