|
|
// Affected devices: all mesa drivers

// Started Version: 9.0 (mesa doesn't support ubo before)
|
|
// Ended Version: up to 9.2
|
|
// The offset of glBindBufferRange was ignored on all Mesa Gallium3D drivers until 9.1.3
|
|
// Nouveau stored the offset as u16 which isn't enough for all cases with range until 9.1.6
|
|
// I965 has broken data fetches from uniform buffers which results in a dithering until 9.2.0

BUG_BROKENUBO,

// Affected devices: AMD as they are the only vendor providing this extension
|

// Started Version: ?
|
|
// Ended Version: 13.9 working for me (neobrain).
|
|
// Affected OS: Linux
|
|
// Pinned memory is disabled for index buffer as the AMD driver (the only one with pinned memory support) seems
|
|
// to be broken. We just get flickering/black rendering when using pinned memory here -- degasus - 2013/08/20
|
|
// This bug only happens when paired with base_vertex.
|
|
// Please see issue #6105 on Google Code. Let's hope buffer storage solves this issues.

// TODO: Detect broken drivers.

BUG_BROKENPINNEDMEMORY,

// Bug: glBufferSubData/glMapBufferRange stalls + OOM
|
|
// Affected devices: Adreno a3xx/Mali-t6xx
|
|
// Started Version: -1
|
|
// Ended Version: -1
|
|
// Both Adreno and Mali have issues when you call glBufferSubData or glMapBufferRange
|
|
// The driver stalls in each instance no matter what you do
|
|
// Apparently Mali and Adreno share code in this regard since it was wrote by the same person.

BUG_BROKENBUFFERSTREAM,

// Bug: ARB_buffer_storage doesn't work with ARRAY_BUFFER type streams
|
|
// Affected devices: GeForce 4xx+
|
|
// Started Version: -1
|
|
// Ended Version: 332.21
|
|
// The buffer_storage streaming method is required for greater speed gains in our buffer streaming
|
|
// It reduces what is needed for streaming to basically a memcpy call
|

// It seems to work for all buffer types except GL_ARRAY_BUFFER

// Bug: unsync mapping doesn't work fine
|
|
// Affected devices: Nvidia driver
|
|
// Started Version: -1
|
|
// Ended Version: -1
|
|
// The Nvidia driver (both Windows + Linux) doesn't like unsync mapping performance wise.
|
|
// Because of their threaded behavior, they seem not to handle unsync mapping complete unsync,
|
|
// in fact, they serialize the driver which adds a much bigger overhead.
|
|
// Workaround: Use BufferSubData
|
|
// TODO: some Windows AMD driver/GPU combination seems also affected

// Ended Version: 15.36.7.64.3960 (10.18.10.3960)

// Bug: Qualcomm has broken boolean negation
|
|
// Affected devices: Adreno
|
|
// Started Version: -1
|
|
// Ended Version: -1
|
|
// Qualcomm has the boolean negation broken in their shader compiler
|
|
// Instead of inverting the boolean value it does a binary negation on the full 32bit register
|
|
// This causes a compare against zero to fail in their shader since it is no longer a 0 or 1 value
|
|
// but 0xFFFFFFFF or 0xFFFFFFFE depending on what the boolean value was before the negation.
|
|
//
|
|
// This bug has a secondary issue tied to it unlike other bugs.
|
|
// The correction of this bug is to check the boolean value against false which results in us
|
|
// not doing a negation of the source but instead checking against the boolean value we want.
|
|
// The issue with this is that Intel's Window driver is broken when checking if a boolean value is
|
|
// equal to true or false, so one has to do a boolean negation of the source
|
|
//
|
|
// eg.
|
|
// Broken on Qualcomm
|
|
// Works on Windows Intel
|
|
// if (!cond)

//
|
|
// Works on Qualcomm
