* tgsi: add option to dump floats as hex valuesDave Airlie2015-10-233-2/+30
| | | | | | | | | | | This adds support to the parser to accept hex values as floats, and then adds support to the dumper to allow the user to select to dump float as 32-bit hex numbers. This is required to get accurate values for virgl use of TGSI. Reviewed-by: Marek Olšák <marek.olsak@amd.com> Signed-off-by: Dave Airlie <airlied@redhat.com>

* draw: fix splitting of line loops (v2)Brian Paul2015-10-204-8/+32
| | | | | | | | | | | | | | | | | When the draw module splits long line loops, the sections are emitted as line strips. But the primitive type wasn't set correctly so each section was being drawn as a loop, introducing extra line segments. To fix this, we pass a new DRAW_LINE_LOOP_AS_STRIP flag to the run() function. The linear/elt_run() functions have to check for this flag and set their primitive type accordingly. No piglit regressions. Fixes piglit's lineloop with -count 4097 or higher.

* gallium: add PIPE_SHADER_CAP_MAX_UNROLL_ITERATIONS_HINTMarek Olšák2015-10-202-0/+4
| | | | | | | | | | | | | | This avoids a serious r600g bug leading to a GPU hang. The chances this bug will get fixed are pretty low now. I deeply regret listening to others and not pushing this patch, leaving other users with a GPU-crashing driver. Yes, it should be fixed in the compiler and it's ugly, but users couldn't care less about that.

* gallivm: Allow drivers and state trackers to initialize gallivm LLVM targets v2Tom Stellard2015-10-022-7/+32
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Drivers and state trackers that use LLVM for generating code, must register the targets they use with LLVM's global TargetRegistry. The TargetRegistry is not thread-safe, so all targets must be added to the registry before it can be queried for target information. When drivers and state trackers initialize their own targets, they need a way to force gallivm to initialize its targets at the same time. Otherwise, there can be a race condition in some multi-threaded applications (e.g. glx-multihreaded-shader-compile in piglit), when one thread creates a context for a driver that uses LLVM (e.g. radeonsi) and another thread creates a gallivm context (glxContextCreate does this). The race happens when the driver thread initializes its LLVM targets and then starts using the registry before the gallivm thread has a chance to register its targets. This patch allows users to force gallivm to register its targets by calling the gallivm_init_llvm_targets() function. v2: - Use call_once and remove mutexes and static initializations. - Replace gallivm_init_llvm_{begin,end}() with gallivm_init_llvm_targets().

* llvmpipe: convert double to long long instead of unsigned long longOded Gabbay2015-09-041-1/+1
| | | | | | | | | | | | | | | | | round(val*dscale) produces a double result, as val and dscale are double. However, LLVMConstInt receives unsigned long long, so there is an implicit conversion from double to unsigned long long. This is an undefined behavior. Therefore, we need to first explicitly convert the round result to long long, and then let the compiler handle conversion from that to unsigned long long. This bug manifests itself in POWER, where all IMM values of -1 are being converted to 0 implicitly, causing a wrong LLVM IR output.

| | | | | | | | | These functions deal with inclusive coordinates, hence a 0/0/0/0 rect returned when there's no intersection doesn't actually represent an empty rectangle. Hence return 0/-1/0/-1 instead.

| | | | | | | | | | | | It isn't really obvious if intersection test should take into account empty rectangles or if the caller should do it. But it looks like most callers actually verified one of the rects but not the other, but since correctly returning an empty rect that other rect could actually be empty leading to more bugs. Hence just verify both rects for emptyness in the intersection test itself which makes the code easier in the caller (though it will be slower if the caller knows the rectangles are non-empty).
