Fixed does only mean that it can't be directly manipulated by applications. The
driver has to modify it anyway on about every mode change (line_length). Yes
perhaps some of these fields would be in var today and certainly others
shouldn't exist at all but I do not blame anyone for not being capable to look
into the future.

I think it's more like a FB_VISUAL_FOURCC as you want to express how the color
<-> pixel mapping is. The FB_TYPE_* is more about whether pixel are packed or
represented as planes (the 2 format groups mentioned on fourcc.org).
That's certainly something I'd introduce as it would (hopefully) work to
prevent
old applications which don't know your extension manipulating a FOURCC format
thinking that it is RGB.
So I think we should
fix.visual = FB_VISUAL_FOURCC;
fix.type = FB_TYPE_PACKED_PIXELS | FB_TYPE_PLANES; /* (?) */
or maybe add a FB_TYPE_FOURCC and rely only on the information in FOURCC (as
things like UYVY could become confusing as macropixel!=pixel)

var.grayscale = ;
var.vmode = FB_VMODE_FOURCC;
and if this vmode flag is not set it means traditional mode (based on RGBA).

Sure. But it's good to let the application know whether you support the new
extension or whether you just ignore the flag. So I'm voting for a

If we change from 2.6.X to 3.X, then if we don't change anything else, then successive stable release will cause the LINUX_VERSION_CODE to be incremented.

As long as 3.14 turns into a long-term support kernel and gets up to 159 ... In all serious, I'm very supportive of this move.

Another advantage of switching numbering models (ie 3.0 instead of 2.8.x) would be that it would also make the "odd numbers are also numbers" transition much more natural. Because of our historical even/odd model, I wouldn't do a 2.7.x - there's just too much history of 2.1, 2.3, 2.5 being development trees. But if I do 3.0, then I'd be chucking that whole thing out the window, and the next release would be 3.1, 3.2, etc.. And then in another few years (probably before getting close to 3.40, so I'm not going to make a big deal of 3 = "third decade"), I'd just do 4.0 etc. Because all our releases are supposed to be stable releases these days, and if we get rid of one level of numbering, I feel perfectly fine with getting rid of the even/odd history too.

I always thought that pix_format describes the layout of video data in memory on byte level, which is exactly the same on both little- and big- endian systems. You can notice swapped data only if you access memory by units larger than byte, like 16bit or 32bit integers. BTW - I would really like to avoid little- and big- endian flame, but your statement about 'everything is swapped on a big endian system' is completely wrong.

But no, it wouldn't be for 42. Despite THHGTTG, I think "40" is a fairly nice round number. There's also the timing issue - since we no longer do version numbers based on features, but based on time, just saying "we're about to start the third decade" works as well as any other excuse.

(Short?) merge window reminder
So I've been busily merging stuff, and just wanted to send out a quick reminder that I warned people in the 39 announcement that this might be a slightly shorter merge window than usual, so that I can avoid having to make the -rc1 release from Japan using my slow laptop (doing "allyesconfig" builds on that thing really isn't in the cards, and I like to do those to verify things - even if we've already had a few cases where arch include differences made it less than effective in finding problems). And judging by the merge window so far, that early close (probably Sunday - I'll be on airplanes next Monday) looks rather likely. I already seem to have a fairly sizable portion of linux-next in my tree, and there haven't been any huge upsets. So anybody who was planning a last-minute "please pull" - this is a heads-up. Don't do it, you might miss the window entirely. Did I miss any major development mailing lists with stuff pending? Linus PS. The voices in my head also tell me that the numbers are getting too big. I may just call the thing 2.8.0. And I almost guarantee that this PS is going to result in more discussion than the rest, but when the voices tell me to do things, I listen.

(Short?) merge window reminder
So I've been busily merging stuff, and just wanted to send out a quick reminder that I warned people in the 39 announcement that this might be a slightly shorter merge window than usual, so that I can avoid having to make the -rc1 release from Japan using my slow laptop (doing allyesconfig builds on that thing really isn't in the cards, and I like to do those to verify things - even if we've already had a few cases where arch include differences made it less than effective in finding problems). And judging by the merge window so far, that early close (probably Sunday - I'll be on airplanes next Monday) looks rather likely. I already seem to have a fairly sizable portion of linux-next in my tree, and there haven't been any huge upsets. So anybody who was planning a last-minute please pull - this is a heads-up. Don't do it, you might miss the window entirely. Did I miss any major development mailing lists with stuff pending? Linus PS. The voices in my head also tell me that the numbers are getting too big. I may just call the thing 2.8.0. And I almost guarantee that this PS is going to result in more discussion than the rest, but when the voices tell me to do things, I listen. ___ dri-devel mailing list dri-devel@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/dri-devel

Re: [RFC] Standardize YUV support in the fbdev API

Hi everybody,
I need to implement support for a YUV frame buffer in an fbdev driver. As
the fbdev API doesn't support this out of the box, I've spent a couple
of days reading fbdev (and KMS) code and thinking about how we could
cleanly add YUV support to the API. I'd like to share my findings and
thoughts, and hopefully receive some comments back.
Thanks. I think you did already a good job, hope we can get it done this
time.
Thanks. I'll keep pushing then :-)
Given the overlap between the KMS, V4L2 and fbdev APIs, the need to share
data and buffers between those subsystems, and the planned use of V4L2
FCCs in the KMS overlay API, I believe using V4L2 FCCs to identify fbdev
formats would be a wise decision.
I agree.
There seems to be a general agreement on this, so I'll consider this settled.
To select a frame buffer YUV format, the fb_var_screeninfo structure will
need to be extended with a format field. The fbdev API and ABI must not
be broken, which prevents us from changing the current structure layout
and replacing the existing format selection mechanism (through the red,
green, blue and alpha bitfields) completely.
I agree.
- Other solutions are possible, such as adding new ioctls. Those
solutions are more intrusive, and require larger changes to both
userspace and kernelspace code.
I'm against (ab)using the nonstd field (probably the only sane thing we can
do with it is declare it non-standard which interpretation is completely
dependent on the specific driver) or requiring previously unused fields to
have a special value so I'd like to suggest a different method:

(RGB, YCbCr), FB_TYPE_* would be a format specifier (i.e. planar,
semiplanar, interleaved, etc)? I'm not really sure what you are
referring to with the FB_AUX_* however.
Yep, FB_TYPE_* specifies how pixel values/tuples are laid out in frame
buffer memory.
FB_AUX_* is only used if a specific value of FB_TYPE_* needs an
additional parameter (e.g. the interleave value for interleaved
bitplanes).
Adding new standard values for these fb_fix_screeninfo fields would solve
the issue for framebuffers which only support a single format.
I've never liked changing fixed screen information :-) It would be consistent
with the API though.
If you have the need to switch
Yes I need that. This requires an API to set the mode through
fb_var_screeninfo, which is why I skipped modifying fb_fix_screeinfo.
A new FB_TYPE_* could be used to report that we use a 4CC-based mode, with the
exact mode reported in one of the fb_fix_screeninfo reserved fields (or the
type_aux field). This would duplicate the information passed through
fb_var_screeninfo though. Do you think it's worth it ?
I guess it would be a good idea to add a new flag to the vmode bitfield in
fb_var_screeninfo which looks like a general purpose modifier for the
videomode. You could than reuse any RGB-specific field you like to pass more
information.
That looks good to me. The grayscale field could be reused to pass the 4CC.
Maybe we should also use this chance to declare one of the fix_screeninfo
reserved fields to be used for capability flags or an API version as we can
assume that those are 0 (at least in sane drivers).
That's always good, although it's not a hard requirement for the purpose of
YUV support.

Fixed does only mean that it can't be directly manipulated by applications. The
driver has to modify it anyway on about every mode change (line_length). Yes
perhaps some of these fields would be in var today and certainly others
shouldn't exist at all but I do not blame anyone for not being capable to look
into the future.
If you have the need to switch
Yes I need that. This requires an API to set the mode through

fb_var_screeninfo though. Do you think it's worth it ?
I think it's more like a FB_VISUAL_FOURCC as you want to express how the color
- pixel mapping is. The FB_TYPE_* is more about whether pixel are packed or
represented as planes (the 2 format groups mentioned on fourcc.org).
That's certainly something I'd introduce as it would (hopefully) work to prevent
old applications which don't know your extension manipulating a FOURCC format
thinking that it is RGB.
So I think we should
fix.visual = FB_VISUAL_FOURCC;
fix.type = FB_TYPE_PACKED_PIXELS | FB_TYPE_PLANES; /* (?) */
or maybe add a FB_TYPE_FOURCC and rely only on the information in FOURCC (as
things like UYVY could become confusing as macropixel!=pixel)
I guess it would be a good idea to add a new flag to the vmode bitfield in
fb_var_screeninfo which looks like a general purpose modifier for the
videomode. You could than reuse any RGB-specific field you like to pass more
information.
That looks good to me. The grayscale field could be reused to pass the 4CC.
var.grayscale = FOURCC_FORMAT;
var.vmode = FB_VMODE_FOURCC;
and if this vmode flag is not set it means traditional mode (based on RGBA).
Maybe we should also use this chance to declare one of the fix_screeninfo
reserved fields to be used for capability flags or an API version as we can
assume that those are 0 (at least in sane drivers).
That's always good, although it's not a hard requirement for the purpose of
YUV support.
Sure. But it's good to let the application know whether you support the new
extension or whether you just ignore the flag. So I'm voting for a
fix.caps = FB_CAP_FOURCC;

Another advantage of switching numbering models (ie 3.0 instead of 2.8.x) would be that it would also make the odd numbers are also numbers transition much more natural. Because of our historical even/odd model, I wouldn't do a 2.7.x - there's just too much history of 2.1, 2.3, 2.5 being development trees. But if I do 3.0, then I'd be chucking that whole thing out the window, and the next release would be 3.1, 3.2, etc.. And then in another few years (probably before getting close to 3.40, so I'm not going to make a big deal of 3 = third decade), I'd just do 4.0 etc. Because all our releases are supposed to be stable releases these days, and if we get rid of one level of numbering, I feel perfectly fine with getting rid of the even/odd history too.

Yeah, it sounds really good to get rid of the (meanwhile) meaningless 2.6. prefix from our version code and iterate it in a more meaningful way. I suspect the stable team and distros will enjoy the more meaningful third digit as well: it will raise the perceived importance of stabilization and packaging work. Btw., we should probably remove the fourth (patch) level, otherwise distros might feel tempted to fill it in with their own patch-stack version number, which would result in confusing 3.3.1.5 meaning different things on different distros - while 3.3.1-5.rpm style of distro kernel package naming denotes the distro patch level more clearly. I don't think the odd/even history will linger too long: in practice we'll iterate through 3.1, 3.2, 3.3 and 3.4 rather quickly, in the first year, so any residual notion of stable/unstable will be gone within a few iterations.

And then in another few years (probably before getting close to 3.40, so I'm not going to make a big deal of 3 = third decade), I'd just do 4.0 etc. Perhaps we could do 4.0 once the last bit of -rt hits upstream? /me ducks Because all our releases are supposed to be stable releases these days, and if we get rid of one level of numbering, I feel perfectly fine with getting rid of the even/odd history too. They are very stable releases as far as i'm concerned - i can pretty confidently run and use -rc2 and better kernels on my boxes these days and could do so for the past few years.

But no, it wouldn't be for 42. Despite THHGTTG, I think 40 is a fairly nice round number. Also, in all fairness, we should probably display a certain amount of humility: while Linux has certainly reached milestones such as world domination (as far as large and small computers are concerned), so calling it 3.0 is a fair deal, we probably have to wait for version 42.0 before we can consider the Linux kernel to be the ultimate answer to life, universe and everything.
