| * [PATCH] ll_rw_blk: fix missing bounce in blk_rq_map_kern()Mike Christie2007-05-08
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | I think we might just need the blk_map_kern users now. For the async execute I added the bounce code already and the block SG_IO has it atleady. I think the blk_map_kern bounce code got dropped because we thought the correct gfp_t would be passed in. But I think all we need is the patch below and all the paths are take care of. The patch is not tested. Patch was made against scsi-misc. The last place that is sending non sg commands may just be md/dm-emc.c but that is is just waiting on alasdair to take some patches that fix that and a bunch of junk in there including adding bounce support. If the patch below is ok though and dm-emc finally gets converted then it will have sg and bonce buffer support.

| * [PATCH] splice(): fix interaction with readaheadFengguang Wu2007-05-08
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Eric Dumazet, thank you for disclosing this bug. Readahead logic somehow fails to populate the page range with data. It can be because 1) the readahead routine is not always called in the following lines of fs/splice.c: if (!loff || nr_pages > 1) page_cache_readahead(mapping, &in->f_ra, in, index, nr_pages); 2) even called, page_cache_readahead() wont guarantee the pages are there. It wont submit readahead I/O for pages already in the radix tree, or when (ra_pages == 0), or after 256 cache hits. In your case, it should be because of the retried reads, which lead to excessive cache hits, and disables readahead at some time. And that _one_ failure of readahead blocks the whole read process. The application receives EAGAIN and retries the read, but __generic_file_splice_read() refuse to make progress: - in the previous invocation, it has allocated a blank page and inserted it into the radix tree, but never has the chance to start I/O for it: the test of SPLICE_F_NONBLOCK goes before that. - in the retried invocation, the readahead code will neither get out of the cache hit mode, nor will it submit I/O for an already existing page.

This problem stems from continuously writing text to the system console (which is in KD_TEXT mode) while the foreground console is in KD_GRAPHICS mode. Somewhere along the way, console printing got confused and omitted the KD_GRAPHICS/KD_TEXT test. Thus, vgacon attempted to scroll the screen of X, which causes X to shift. Fix by disallowing vgacon to touch the hardware when the vc is in KD_GRAPHICS mode. A definitive fix entails a full audit of the console code.

| | | | | | | | | | | | | | | | | | | | | | | | Implement fb_get_tilemax(). It just returns 256. Signed-off-by: Antonino Daplas <adaplas@gmail.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
* | | fbdev: add tile operation to get the maximum length of the mapAntonino A. Daplas2007-05-08
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add a tile method, fb_get_tilemax(), that returns the maximum length of the tile map (or font map). This is needed by s3fb which can only handle 256 characters.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If tileblitting is enabled (text mode), the hardware can only accept 8x16 bitmaps. Advertise this to the upper layer. And to ensure that an appropriate font is always available, select an 8x16 font in Kconfig.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Advertise that vga16fb can only handle widths that are 8-pixel-multiple only (software limitation).

* | | fbcon: font setting should check limitation of driverAntonino A. Daplas2007-05-08
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | fbcon_set_font() will now check if the new font dimensions can be drawn by the driver (by checking pixmap.blit_x and blit_y). Similarly, add 2 new parameters to get_default_font(), font_w and font_h, to further aid in the font selection process.

* | | fbdev: advertise limitation of drawing engineAntonino A. Daplas2007-05-08
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | A few drivers are not capable of blitting rectangles of any dimension. vga16fb can only blit 8-pixel wide rectangles, while s3fb (in tileblitting mode) can only blit 8x16 rectangles. For example, loading a 12x22 font in vga16fb will result in a corrupt display. Advertise this limitation/capability in info->pixmap.blit_x and blit_y. These fields are 32-bit arrays (font max is 32x32 only), ie, if bit 7 is set, then width/height of 7+1 is supported.
