freedreno: fix sysmem rendering being used when clear is used

This batch->cleared value is only used to decide to use sysmem rendering
or not, so it should include any buffers that are affected by a clear.

This is required because the a2xx fast clear doesn't work with sysmem
rendering. The a22x "normal" clear path doesn't work with sysmem either.

egl/wayland: Allow client->server format conversion for PRIME offload. (v2)

Support PRIME render offload between a Wayland server gpu and a Wayland
client gpu with different channel ordering for their color formats,
e.g., between Intel drivers which currently only support ARGB2101010
and XRGB2101010 import/display and nouveau which only supports ABGR2101010
rendering and display on nv-50 and later.

In the wl_visuals table, we also store for each format an alternate
sibling format which stores colors at the same precision, but with
different channel ordering, e.g., ARGB2101010 <-> ABGR2101010.

If a given client-gpu renderable format is not supported by the server
for import, but the alternate format is supported by the server, expose
the client-gpu renderable format as a valid EGLConfig to the client. At
eglSwapBuffers time, during the blitImage() detiling blit from the client
backbuffer to the linear buffer, the client format is converted to the
server supported format. As we have to do a copy for PRIME anyway,
this channel swizzling conversion comes essentially for free.

Note that even if a server gpu in principle does support sampling
from the clients native format, this conversion will be a performance
advantage if it allows to convert to the servers preferred format
for direct scanout, as the Wayland compositor may then be able to
directly page-flip a fullscreen client wl_buffer onto the primary
plane, or onto a hardware overlay plane, avoiding an extra data copy
for desktop composition.

Tested so far under Weston with: nouveau single-gpu, Intel single-gpu,
AMD single-gpu, "Optimus" Intel server iGPU for display + NVidia
client dGPU for rendering.

v2: Implement minor review comments by Eric Engestrom: Add some

spirv/nir: handle location decorations on block interface members

Previously the code was taking any location decoration on the block
and using that to calculate the member locations for all of the
members. I think this was assuming that there would only be one
location decoration for the entire block. According to the Vulkan spec
it is possible to add location decorations to individual members:

   “If the structure type is a Block but without a Location, then each
    of its members must have a Location decoration. If it is a Block
    with a Location decoration, then its members are assigned
    consecutive locations in declaration order, starting from the
    first member which is initially the Block. Any member with its own
    Location decoration is assigned that location. Each remaining
    member is assigned the location after the immediately preceding
    member in declaration order.”

This patch makes it instead keep track of which members have been
assigned an explicit location. It also has a space to store the
location for the struct as a whole. Once all the decorations have been
processed it iterates over each member to fill in the missing
locations using the rules described above.

So, this commit is needed to get working a case like this, on both
Vulkan and OpenGL using SPIR-V (ARB_gl_spirv):

     out block {
            layout(location = 2) vec4 c;
            layout(location = 3) vec4 d;
            layout(location = 0) vec4 a;
            layout(location = 1) vec4 b;
     } name;

v2: (changes made by Alejandro Piñeiro)
   * Update after introducing struct member splitting (See commit b0c643d)
   * Update after only exposing interface_type for blocks, not to any struct

5 years agoradv: add device->instance extension dependencies
Niklas Haas [Thu, 22 Nov 2018 23:32:28 +0000 (00:32 +0100)]
radv: add device->instance extension dependencies

From the vulkan spec 33.3 "Extension Dependencies":

"Any device extension that has an instance extension dependency that is
not enabled by vkCreateInstance is considered to be unsupported, hence
it must not be returned by vkEnumerateDeviceExtensionProperties for any
VkPhysicalDevice child of the instance."

Therefore we need to check whether the instance-level extensions are
actually enabled when deciding to support a device-level extension or
not.

Furthermore, we need to do this for all instance-level extensions of any
(transitive) device-level extension dependency, due to the following
paragraph:

"If an extension is supported (as queried by
vkEnumerateInstanceExtensionProperties or
vkEnumerateDeviceExtensionProperties), then required extensions of that
extension must also be supported for the same instance or physical
device."

Finally, because some of these vulkan extensions may be implicitly
promoted to future vulkan core API versions, we can also satisfy the
dependency if the vulkan API version is high enough.

5 years agoglsl: fix block member alignment validation for vec3
Niklas Haas [Sun, 16 Dec 2018 04:40:14 +0000 (05:40 +0100)]
glsl: fix block member alignment validation for vec3

Section 7.6.2.2 (Standard Uniform Block Layout) of the GL spec says:

    The base offset of the first member of a structure is taken from the
    aligned offset of the structure itself. The base offset of all other
    structure members is derived by taking the offset of the last basic
    machine unit consumed by the previous member and adding one.

The current code does not reflect this last sentence - it effectively
instead aligns up the next offset up to the alignment of the previous
member. This causes an issue in exactly one case:

layout(std140) uniform block {
    layout(offset=0) vec3 var1;
    layout(offset=12) float var2;
};

As per section 7.6.2.1 (Uniform Buffer Object Storage) and elsewhere, a
vec3 consumes 3 floats, i.e. 12 basic machine units. Therefore, `var1`
in the example above consumes units 0-11, with 12 being the first
available offset afterwards. However, before this commit, mesa
incorrectly assumes `var2` must start at offset=16 when using explicit
offsets, which results in a compile-time error. Without explicit
offsets, the shaders actually work fine, indicating that mesa is already
correctly aligning these fields internally. (Just not in the code that
handles explicit buffer offset parsing)

This patch should fix piglit tests:
ssbo-explicit-offset-vec3.vert
ubo-explicit-offset-vec3.vert
