Ryan Houdek 9108a11af4 Change driver details to reflect Qualcomm's changes with their v95 driver.
They fixed their issues with dynamic UBO array member access.
There are many other issues though.

enum Bug
{
// Bug: No Dynamic UBO array object access
// Affected Devices: Qualcomm/Adreno
// Started Version: 14
// Ended Version: 95
// Accessing UBO array members dynamically causes the Adreno shader compiler to crash
// Errors out with "Internal Error"
// With v53 video drivers, dynamic member access "works." It works to the extent that it doesn't crash.
// With v95 drivers everything works as it should.
BUG_NODYNUBOACCESS = 0,
// Bug: Centroid is broken in shaders
// Affected devices: Qualcomm/Adreno
// Started Version: 14
// Ended Version: 53
// Centroid in/out, used in the shaders, is used for multisample buffers to get the texel correctly
// When MSAA is disabled, it acts like a regular in/out
// Tends to cause the driver to render full white or black
BUG_BROKENCENTROID,
// Bug: INFO_LOG_LENGTH broken
// Affected devices: Qualcomm/Adreno
// Started Version: ? (Noticed on v14)
// Ended Version: 53
// When compiling a shader, it is important that when it fails,
// you first get the length of the information log prior to grabbing it.
// This allows you to allocate an array to store all of the log
// Adreno devices /always/ return 0 when querying GL_INFO_LOG_LENGTH
// They also max out at 1024 bytes(1023 characters + null terminator) for the log
BUG_BROKENINFOLOG,
// Bug: UBO buffer offset broken
// 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,
// Bug: The pinned memory extension isn't working for index buffers
// 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: Entirely broken UBOs
// Affected devices: Qualcomm/Adreno
// Started Version: ? (Noticed on v45)
// Ended Version: 53
// Uniform buffers are entirely broken on Qualcomm drivers with v45
// Trying to use the uniform buffers causes a malloc to fail inside the driver
// To be safe, blanket drivers from v41 - v45
BUG_ANNIHILATEDUBOS,
// Bug : Can't draw on screen text and clear correctly.
// Affected devices: Qualcomm/Adreno
// Started Version: ?
// Ended Version: 53
// Current code for drawing on screen text and clearing the framebuffer doesn't work on Adreno
// Drawing on screen text causes the whole screen to swizzle in a terrible fashion
// Clearing the framebuffer causes one to never see a frame.
BUG_BROKENSWAP,
// 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: GLSL ES 3.0 textureSize causes abort
// Affected devices: Adreno a3xx
// Started Version: -1 (Noticed in v53)
// Ended Version: 66
// If a shader includes a textureSize function call then the shader compiler will call abort()
BUG_BROKENTEXTURESIZE,
// 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_BROKENBUFFERSTORAGE,
// Bug: Intel HD 3000 on OS X has broken primitive restart
// Affected devices: Intel HD 3000
// Affected OS: OS X
// Started Version: -1
// Ended Version: -1
// The drivers on OS X has broken primitive restart.
// Intel HD 4000 series isn't affected by the bug
BUG_PRIMITIVERESTART,
// 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 behavoir, 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
// but as they all support pinned memory, it doesn't matter
BUG_BROKENUNSYNCMAPPING,
// Bug: Adreno now rotates the framebuffer on blit a full 180 degrees
// Affected devices: Adreno
// Started Version: v53 (dev drivers)
// Ended Version: v66 (07-14-2014 dev drivers)
// Qualcomm is a super pro company that has recently updated their development drivers
// These drivers are available to the Nexus 5 and report as v53
// Qualcomm in their infinite wisdom thought it was a good idea to rotate the framebuffer 180 degrees on glBlit
// This bug allows us to work around that rotation by rotating it the right way around again.
BUG_ROTATEDFRAMEBUFFER,
// Bug: Intel's Window driver broke buffer_storage with GL_ELEMENT_ARRAY_BUFFER
// Affected devices: Intel (Windows)
// Started Version: 15.36.3.64.3907 (10.18.10.3907)
// Ended Version: 15.36.7.64.3960 (10.18.10.3960)
// Intel implemented buffer_storage in their GL 4.3 driver.
// It works for all the buffer types we use except GL_ELEMENT_ARRAY_BUFFER.
// Causes complete blackscreen issues.
