| | | | | | | | | | | Call ffs() and ffsll() everywhere. Define our own ffs(), ffsll() functions when the platform doesn't have them. v2: remove #ifdef _WIN32, __IBMC__, __IBMCPP_ tests inside ffs() implementation. The #else clause was recursive.

| | | | | | | | | | | | | | | | | first buffer in _mesa_drawbuffers(). Without this we'd miss the last update in a sequence like {COLOR0, COLOR1}, {COLOR0}, {COLOR0, COLOR1}. I originally had a patch for this that called updated_drawbuffers() when the buffer count changed, but later realized that was wrong. The ARB_draw_buffers spec explicitly says "The draw buffer for output colors beyond <n> is set to NONE.", and this is queryable state. This fixes piglit arb_draw_buffers-state_change. NOTE: This is a candidate for the 7.11 branch. Signed-off-by: Henri Verbeet <[email protected]> Reviewed-by: Brian Paul <[email protected]> Reviewed-by: Eric Anholt <[email protected]>

* mesa: Flush vertices before updating drawbuffer computed state.Eric Anholt2011-05-261-7/+7
| | | | | | | Otherwise, the driver is likely to draw the flushed vertices to the new drawbuffer instead of the old one, missing the point of the flush. Reviewed-by: Brian Paul <[email protected]>
* mesa: Trigger FBO validation on DrawBuffers change in non-ES2 mode.Eric Anholt2011-05-261-10/+26
| | | | | | | | | glDrawBuffers pointing at an unattached buffer is supposed to be incomplete without ARB_ES2_compatibility. The testcase to catch the bug of not implementing that bit of the spec was tricked by this missing piece of state update. Reviewed-by: Brian Paul <[email protected]>

* mesa: in glReadBufer() set _NEW_BUFFERS, not _NEW_PIXELBrian Paul2009-05-011-1/+1
| | | | | | | | | | | | | | | Since GL_READ_BUFFER is historically part of the gl_pixel_attrib group it made sense to signal changes with _NEW_PIXEL. But now with FBOs it's also part of the framebuffer state. Now _NEW_PIXEL strictly indicates pixels transfer state changes. This change avoids framebuffer state validation when any random bit of pixel-transfer state is set. DRI drivers updated too: don't check _NEW_COLOR when updating framebuffer state. I think that was just copied from the Xlib driver because we care about dither enable/disable state there.
* mesa: fix glRead/DrawBuffer(GL_AUXn) error valueBrian Paul2009-03-121-0/+8
| | | | | | | If GL_AUX[123] are passed to glRead/DrawBuffer() when those buffers don't exist, need to generate GL_INVALID_OPERATION, not GL_INVALID_ENUM. This regression came from commit 555f0a88182e2b1af809b2d97abdac02814a2f28
* mesa: remove unused AUX buffersBrian Paul2009-03-021-12/+0
| | | | | | Remove all references to aux buffers 1..3. Keep AUX0 around for now just in case, but it'll probably go too someday. I don't know of any OpenGL drivers since the IRIX days that support aux color buffers.
* glDrawBuffers(n==0) is validRobert Ellison2009-02-121-3/+8
| | | | | | | | | | | | | | According to the GL spec, calling glDrawBuffers() with n == 0 is a valid operation (and essentially prevents drawing to any buffers). But _msa_DrawBuffersARB() was producing a GL_INVALID_VALUE error in this case. This fix adjusts the error check, and makes a small change to the ctx->Driver.DrawBuffer() call below to ensure that, if n == 0, Driver.DrawBuffer() is called with GL_NONE and that buffers[0] is *not* referenced in this case (since we don't know whether it is valid).

| | | | | | | | | | | | | | | | | | | | | | | | | | | Previously, we set _NEW_PIXEL and _NEW_COLOR in these functions, respectively. That correponds to the GL attribute groups, but doesn't make much sense otherwise. This could improve validation efficiency in a few places too. It looks like all the drivers are already checking for _NEW_BUFFERS in the right places (since that's the bit for FBO state) so we can trim out _NEW_PIXEL and _NEW_COLOR at any time.
