2008-12-30virtio_blk: fix type warningRandy Dunlap
Fix parameter type warning: linux-next-20081126/drivers/block/virtio_blk.c:307: warning: large integer implicitly truncated to unsigned type Signed-off-by: Randy Dunlap <randy.dunlap@oracle.com> cc: Rusty Russell <rusty@rustcorp.com.au> Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
2008-12-30virtio: block: dynamic maximum segmentsRusty Russell
Enhance the driver to handle whatever maximum segment number the host tells us to handle. Do to this, we need to allocate the scatterlist dynamically. We set max_phys_segments and max_hw_segments to the same value (1 if the host doesn't tell us, since that's safest and all known hosts do tell us). Note that kmalloc'ing the structure for large sg_elems might be problematic: the fix for this is sg_table, but that requires more work. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
2008-12-30virtio: set max_segment_size and max_sectors to infinite.Rusty Russell
Setting max_segment_size allows more than 64k per sg element, unless the host specified a limit. Setting max_sectors indicates that our max_hw_segments is the only limit. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
2008-12-30virtio: avoid implicit use of Linux page size in balloon interfaceHollis Blanchard
Make the balloon interface always use 4K pages, and convert Linux pfns if necessary. This patch assumes that Linux's PAGE_SHIFT will never be less than 12. Signed-off-by: Hollis Blanchard <hollisb@us.ibm.com> Signed-off-by: Rusty Russell <rusty@rustcorp.com.au> (modified)
2008-12-30virtio: hand virtio ring alignment as argument to vring_new_virtqueueRusty Russell
This allows each virtio user to hand in the alignment appropriate to their virtio_ring structures. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au> Acked-by: Christian Borntraeger <borntraeger@de.ibm.com>
2008-12-30virtio: use KVM_S390_VIRTIO_RING_ALIGN instead of relying on pagesizeRusty Russell
This doesn't really matter, since s390 pagesize is 4k anyway. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au> Acked-by: Christian Borntraeger <borntraeger@de.ibm.com>
2008-12-30virtio: use LGUEST_VRING_ALIGN instead of relying on pagesizeRusty Russell
This doesn't really matter, since lguest is i386 only at the moment, but we could actually choose a different value. (lguest doesn't have a guarenteed ABI). Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
2008-12-30virtio: Don't use PAGE_SIZE for vring alignment in virtio_pci.Rusty Russell
That doesn't work for non-4k guests which are now appearing. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
2008-12-30virtio: rename 'pagesize' arg to vring_init/vring_sizeRusty Russell
It's really the alignment desired for consumer/producer separation; historically this x86 pagesize, but with PowerPC it'll still be x86 pagesize. And in theory lguest could choose a different value. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
2008-12-30virtio: Don't use PAGE_SIZE in virtio_pci.cRusty Russell
The virtio PCI devices don't depend on the guest page size. This matters now PowerPC virtio is gaining ground (they like 64k pages). Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
2008-12-30virtio: struct device - replace bus_id with dev_name(), dev_set_name()Kay Sievers
This patch is part of a larger patch series which will remove the "char bus_id[20]" name string from struct device. The device name is managed in the kobject anyway, and without any size limitation, and just needlessly copied into "struct device". To set and read the device name dev_name(dev) and dev_set_name(dev) must be used. If your code uses static kobjects, which it shouldn't do, "const char *init_name" can be used to statically provide the name the registered device should have. At registration time, the init_name field is cleared, to enforce the use of dev_name(dev) to access the device name at a later time. We need to get rid of all occurrences of bus_id in the entire tree to be able to enable the new interface. Please apply this patch, and possibly convert any remaining remaining occurrences of bus_id. We want to submit a patch to -next, which will remove bus_id from "struct device", to find the remaining pieces to convert, and finally switch over to the new api, which will remove the 20 bytes array and does no longer have a size limitation.

2008-12-30virtio-pci queue allocation not page-alignedHollis Blanchard
kzalloc() does not guarantee page alignment, and in fact this broke when I enabled CONFIG_SLUB_DEBUG_ON.

2008-12-29V4L/DVB (9764): em28xx: Add support for suspend the device when not usedMauro Carvalho Chehab
Several chips may be turned off when the device is not used, like audio, video and dvb demods. This patch adds a gpio callback at the core structs to allow turning off such devices. Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
2008-12-29V4L/DVB (9763): em28xx: fix gpio settingsMauro Carvalho Chehab
A previous changeset moved gpio from em28xx struct into em28xx_board. However, the driver were not updated to properly honor those gpio's. Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
2008-12-29V4L/DVB (9762): em28xx: fix tuner absent entriesMauro Carvalho Chehab
Before this patch, several devices without tuner were kept the value 0 for tuner_type. However, this means TUNER_TEMIC_PAL. Replace those entries for the proper TUNER_ABSENT value. Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
2008-12-29V4L/DVB (9761): em28xx: replace magic numbers for mux aliasesMauro Carvalho Chehab
Instead of using magic vmux/amux, let's use an alias where possible. Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
2008-12-29V4L/DVB (9760): em28xx: move gpio lines into board table descriptionMauro Carvalho Chehab
Instead of a large, ugly switch specifying the gpio tables for each device, let's move it into the boards struct. This also helps to see what boards have already the gpio's for DVB. Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>

2008-12-29V4L/DVB (9758): em28xx: replace some magic by register descriptions where knownMauro Carvalho Chehab
Replaces all occurrences of em28xx_write_regs_req() and em28xx_write_reg() used to setup register names by em28xx_write_reg(). Also, documents the register names that are known. This patch were generated by this small perl script: my %reg_map = ( # Register table - the same as defined on parse_em28xx.pl script ); while (<>) { if (m/(.*)em28xx_write_regs_req\(dev\,\s*0x00\,\s*(.*)\,\s*\"\\x(..)\",\s*1\)\;(.*)/) { my $reg = $2; my $val = $3; $val =~ tr/A-f/a-f/; $reg = $reg_map{$reg} if defined($reg_map{$reg}); printf "$1em28xx_write_reg(dev, %s, 0x%s);$4\n", $reg, $val; } elsif (m/(.*)em28xx_write_regs\(dev\,\s*(.*)\,\s*\"\\x(..)\",\s*1\)\;(.*)/) { my $reg = $2; my $val = $3; $val =~ tr/A-f/a-f/; $reg = $reg_map{$reg} if defined($reg_map{$reg}); printf "$1em28xx_write_reg(dev, %s, 0x%s);$4\n", $reg, $val; } else { print $_; } } Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>

2008-12-29V4L/DVB (9754): em28xx: improve debug messagesMauro Carvalho Chehab
Now, the first message states board names. Also, removed printing the alternate settings by default. I2C messages are now clearer. Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
2008-12-29V4L/DVB (9753): em28xx: cleanup: saa7115 module auto-detects saa711x typeMauro Carvalho Chehab
Since saa7115 has saa711x chip auto-detection, there's no need on differenciating it at cards table. Just use the generic name for all boards that use a philips saa711x decoder. Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
2008-12-29V4L/DVB (9752): Remove duplicated fields on em28xx_board and em28xx structsMauro Carvalho Chehab
Several fields are duplicated on both structs. Let's just copy em28xx_board instead. A later cleanup could just copy the fields that are changed, in order to keep em28xx_board const. Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
2008-12-29V4L/DVB (9751): em28xx: card description cleanupsMauro Carvalho Chehab
Remove unused em28xx_board.vchannels and em28xx.video_channels. Also, .is_em2800 = 0 is not needed, as all data is zeroed by kernel loader. The table also included a notice that svideo weren't test on Hauppauge USB2. Remove this notice, since this input also works properly. Also, it does some whitespace cleanups. Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
2008-12-29V4L/DVB (9747): em28xx: Properly handles XCLK and I2C speedMauro Carvalho Chehab
The previous patches removed XCLK and I2C magic. Now, we finally know what those registers do. Also, only a very few cards need different setups for those. Instead of keeping the setups for those values inside the per-device hack magic switch, move the uncommon values to the board-specific struct, and have a common setup for all other boards. So, almost 100 lines of hacking magic were removed. A co-lateral effect of this patch is that it also fixes a bug at em28xx-core, where xclk were set, without taking any care about not overriding a previous xclk setup.
