Ross, You mean enable EGL support in MESA, right? Adding extra configure option should be okay. What's mex? Thanks, Edwin 20906 2 ross.burton 2012-04-27 08:28:53 +0000 mex is Media Explorer - http://media-explorer.org/. Whilst typically build using GLX, it's possible to build it using EGL. Mesa is already building libegl, but virtual/egl (as used by the TI drivers IIRC) isn't a provides in Mesa anywhere. 20977 3 edwin.zhai 2012-05-02 07:54:12 +0000 (In reply to comment #2) > mex is Media Explorer - http://media-explorer.org/.

I find "--disable-egl" is appended to the mesa-dri(package of libegl is empty), maybe TI layers orerride it. I'm not sure just adding following line can fix you issue: PROVIDES = "virtual/egl" 20978 4 498 edwin.zhai 2012-05-02 08:25:53 +0000 Created attachment 498 Enable egl in mesa Ross, Does this patch fix your issue. Sorry, I have no environment to test mex. Thanks, Edwin 21178 5 tf+bugs.yocto 2012-05-08 10:13:05 +0000 IIRC, if you turn on egl with --enable-egl you also have to add --enable-shared-glapi. The other thing that is missing from the mesa packaging for building mex (or more precisely cogl) is the gbm library; this gets enabled with --enable-gbm and then has to be packaged. The following bbappend is what I needed to get cogl with kms egl backend to build: https://github.com/Guacamole/meta-guacamole/blob/master/meta-guacamole/recipes-graphics/mesa/mesa-dri_7.11.bbappend. 21232 6 edwin.zhai 2012-05-09 01:46:52 +0000 (In reply to comment #5) > > The following bbappend is what I needed to get cogl with kms egl backend to > build: > https://github.com/Guacamole/meta-guacamole/blob/master/meta-guacamole/ > recipes-graphics/mesa/mesa-dri_7.11.bbappend. TF, Thanks for your patch. Maybe you can push it into the repo for related layer? If making changes in meta/(i.e. oe-core), we need clear usage model: * mesa-dri provides virtual/egl * others inside meta/ also provides virtual/egl * pushed mex into oe-core, to requires virtual/egl oe-core is independent part, other recipes sit in different layer from different repo. So pushing this patch into related repo is a good choice. 22461 7 edwin.zhai 2012-06-21 05:56:44 +0000 Mark it as WONTFIX, because all the required changes are limited in specific layer out of yocto and oe-core. TF already provided patch. 22462 8 tf+bugs.yocto 2012-06-21 07:07:03 +0000 I guess the question is *why* you oe-core is building mesa with egl and dbm disabled? 22519 9 edwin.zhai 2012-06-25 00:57:42 +0000 (In reply to comment #8) > I guess the question is *why* you oe-core is building mesa with egl and dbm > disabled? I guess oe-core is just for common usage like qemu-XXX and other common device. We can ask for turning on egl on the oe-core mailing list with patch. But adding PROVIDES = "virtual/egl" without anybody depending on it is not acceptable.(In reply to comment #8) 23440 10 ross.burton 2012-07-24 13:26:20 +0000 I totally disagree. oe-core should be building all useful variations of Mesa and letting the image/layer pick the ones it needs. If someone is using (say) Clutter on X they'll want GLX, and we're already building that. It's equally useful to use Clutter without X using EGL instead of GLX. oe-core shouldn't be saying that we only support Mesa+GLX, that's the *opposite* of being layer-independent. Also Guacamole was renamed Guacamayo, so the correct URL from Tomas is now https://github.com/Guacamayo/meta-guacamayo/blob/master/meta-guacamayo/recipes-graphics/mesa/mesa-dri_7.11.bbappend. 23463 11 edwin.zhai 2012-07-25 00:30:45 +0000 (In reply to comment #10) > I totally disagree. > > oe-core should be building all useful variations of Mesa and letting the > image/layer pick the ones it needs.

I don't remember I said only support Mesa+GLX. oe-core can support everything as long as it follow the general rules. For PROVIDE/REQUIRE case, we need following: * mesa-dri provides virtual/egl * others inside meta/ also provides virtual/egl * pushed mex into oe-core, to requires virtual/egl. oe-core can support everything, but it should be self-contained system. one provides egl, but nobody inside oe-core requires it, which will be challenged by community. Again, I'm not arguing whether need support egl, but the way how to support. Current patch based on provides/requires is not good enough, until you keep it in your layer. Maybe you can try packages or features? Thanks, Edwin 23475 12 ross.burton 2012-07-25 08:30:39 +0000 > * mesa-dri provides virtual/egl The bbappend does this. > * others inside meta/ also provides virtual/egl Nothing else inside oe-core/meta/ provides EGL. > * pushed mex into oe-core, to requires virtual/egl. mex isn't appropriate for oe-core, it's a large application. 23476 13 richard.purdie 2012-07-25 08:35:12 +0000 I think it is reasonable to enable egl and gbm as long as they get packaged separately. 23664 14 ross.burton 2012-07-31 15:32:56 +0000 I've a branch ross/mesa in poky-contrib that does this along with plenty of other things. 24247 15 ross.burton 2012-08-20 22:00:45 +0000 Richard landed this in oe-core, rev: 03136ebc529dbc82f2db14055e124114da7e84b3. 27326 16 alexandrux.palalau 2012-11-09 14:32:15 +0000 Verified on master branch, commit ID:78983e939ab17f02f8911c8b0d0e326b419856b9 498 2012-05-02 08:25:53 +0000 2012-05-02 08:25:53 +0000 Enable egl in mesa mesa-enable-egl.patch text/plain 1702 edwin.zhai ZGlmZiAtLWdpdCBhL21ldGEvcmVjaXBlcy1ncmFwaGljcy9tZXNhL21lc2EtY29tbW9uLmluYyBi L21ldGEvcmVjaXBlcy1ncmFwaGljcy9tZXNhL21lc2EtY29tbW9uLmluYwppbmRleCAyYjkwYWVk Li43YTMzNWI1IDEwMDY0NAotLS0gYS9tZXRhL3JlY2lwZXMtZ3JhcGhpY3MvbWVzYS9tZXNhLWNv bW1vbi5pbmMKKysrIGIvbWV0YS9yZWNpcGVzLWdyYXBoaWNzL21lc2EvbWVzYS1jb21tb24uaW5j CkBAIC0xMiw3ICsxMiw3IEBAIFNFQ1RJT04gPSAieDExIgogTElDRU5TRSA9ICJNSVQiCiBMSUNf RklMRVNfQ0hLU1VNID0gImZpbGU6Ly9kb2NzL2xpY2Vuc2UuaHRtbDttZDU9N2EzMzczYzAzOWI2 YjkyNWM0Mjc3NTVhNGY3NzljMWQiCiAKLUlOQ19QUiA9ICJyMTMiCitJTkNfUFIgPSAicjE0Igog UEUgPSAiMiIKIAogCkBAIC0yMSw3ICsyMSw3IEBAIExJQl9ERVBTID0gInZpcnR1YWwvbGlieDEx IGxpYnhleHQgbGlieHhmODZ2bSBsaWJ4ZGFtYWdlIGxpYnhmaXhlcyBsaWJ4bWwyLW5hdGl2CiAK IERFUEVORFMgPSAibWFrZWRlcGVuZC1uYXRpdmUgcHl0aG9uLW5hdGl2ZSAke1BST1RPX0RFUFN9 ICR7TElCX0RFUFN9IgogCi1QUk9WSURFUyA9ICJ2aXJ0dWFsL2xpYmdsIgorUFJPVklERVMgPSAi dmlydHVhbC9saWJnbCB2aXJ0dWFsL2VnbCIKIAogIyBmb3IgbWVzYS1kcmkgYW5kIG1lc2EteGxp YgogRklMRVNFWFRSQVBBVEhTX2FwcGVuZCA6PSAiJHtUSElTRElSfS9tZXNhOiIKQEAgLTMxLDcg KzMxLDggQEAgaW5oZXJpdCBhdXRvdG9vbHMgcGtnY29uZmlnCiBFWFRSQV9PRUNPTkYgPSAiLS1l bmFibGUtZ2x1IFwKICAgICAgICAgICAgICAgICAtLWRpc2FibGUtZ2x3IFwKICAgICAgICAgICAg ICAgICAtLWRpc2FibGUtZ2x1dCBcCi0gICAgICAgICAgICAgICAgLS1lbmFibGUtZ2x4LXRscyIK KyAgICAgICAgICAgICAgICAtLWVuYWJsZS1nbHgtdGxzIFwKKyAgICAgICAgICAgICAgICAtLWVu YWJsZS1lZ2wiCiAKICMgTXVsdGlwbGUgdmlydHVhbC9nbCBwcm92aWRlcnMgYmVpbmcgYnVpbHQg YnJlYWtzIHN0YWdpbmcKIEVYQ0xVREVfRlJPTV9XT1JMRCA9ICIxIgpkaWZmIC0tZ2l0IGEvbWV0 YS9yZWNpcGVzLWdyYXBoaWNzL21lc2EvbWVzYS1kcmkuaW5jIGIvbWV0YS9yZWNpcGVzLWdyYXBo aWNzL21lc2EvbWVzYS1kcmkuaW5jCmluZGV4IDQ4MDY3MmYuLjdkZGYxODUgMTAwNjQ0Ci0tLSBh L21ldGEvcmVjaXBlcy1ncmFwaGljcy9tZXNhL21lc2EtZHJpLmluYworKysgYi9tZXRhL3JlY2lw ZXMtZ3JhcGhpY3MvbWVzYS9tZXNhLWRyaS5pbmMKQEAgLTgsNyArOCw3IEBAIERSSURSSVZFUlMg PSAic3dyYXN0IgogRFJJRFJJVkVSU19hcHBlbmRfeDg2ID0gIixpOTE1LGk5NjUiCiBEUklEUklW RVJTX2FwcGVuZF94ODYtNjQgPSAiLGk5MTUsaTk2NSIKIAotRVhUUkFfT0VDT05GICs9ICItLXdp dGgtZHJpdmVyPWRyaSAtLWRpc2FibGUtZWdsIC0tZGlzYWJsZS1nYWxsaXVtIC0td2l0aG91dC1n YWxsaXVtLWRyaXZlcnMgLS13aXRoLWRyaS1kcml2ZXJzPSR7RFJJRFJJVkVSU30iCitFWFRSQV9P RUNPTkYgKz0gIi0td2l0aC1kcml2ZXI9ZHJpIC0tZGlzYWJsZS1nYWxsaXVtIC0td2l0aG91dC1n YWxsaXVtLWRyaXZlcnMgLS13aXRoLWRyaS1kcml2ZXJzPSR7RFJJRFJJVkVSU30iCiAKIHB5dGhv biBwb3B1bGF0ZV9wYWNrYWdlc19wcmVwZW5kKCkgewogCWltcG9ydCBvcy5wYXRoCg==
