For many purposes, including interrupt-swizzling, devices with ARI
enabled behave as if they have one device (number 0) and 256 functions.
This probably hasn't bitten us in practice because all ARI devices I've
seen are also IOV devices, and IOV devices are required to use MSI.
This isn't guaranteed, and there are legitimate reasons to use ARI
without IOV, and hence potentially use pin-based interrupts.

There are 2 problems on mask states in suspend/resume.
[1]:
It is better to restore the mask states of MSI/MSI-X to initial states
(MSI is unmasked, MSI-X is masked) when we release the device.
The pci_msi_shutdown() does the restoration of mask states for MSI,
while the msi_free_irqs() does it for MSI-X. In other words, in the
"disable" path both of MSI and MSI-X are handled, but in the "shutdown"
path only MSI is handled.
MSI:
pci_disable_msi()
=> pci_msi_shutdown()
[ mask states for MSI restored ]
=> msi_set_enable(dev, pos, 0);
=> msi_free_irqs()
MSI-X:
pci_disable_msix()
=> pci_msix_shutdown()
=> msix_set_enable(dev, 0);
=> msix_free_all_irqs
=> msi_free_irqs()
[ mask states for MSI-X restored ]
This patch moves the masking for MSI-X from msi_free_irqs() to
pci_msix_shutdown().
This change has some positive side effects:
- It prevents OS from touching mask states before reading preserved
bits in the register, which can be happen if msi_free_irqs() is
called from error path in msix_capability_init().
- It also prevents touching the register after turning off MSI-X in
"disable" path, which can be a problem on some devices.
[2]:
We have cache of the mask state in msi_desc, which is automatically
updated when msi/msix_mask_irq() is called. This cached states are
used for the resume.
But since what need to be restored in the resume is the states before
the shutdown on the suspend, calling msi/msix_mask_irq() from
pci_msi/msix_shutdown() is not appropriate.
This patch introduces __msi/msix_mask_irq() that do mask as same
as msi/msix_mask_irq() but does not update cached state, for use
in pci_msi/msix_shutdown().
[updated: get rid of msi/msix_mask_irq_nocache() (proposed by Matthew Wilcox)]

The initial state of mask register of MSI is unmasked. We set it
masked before calling arch_setup_msi_irqs(). If arch_setup_msi_irq()
fails, it is better to restore the state of the mask register.

The ALi loses some state if it goes into D3. Unfortunately even with the
chipset documents I can't figure out how to restore some bits of it.
The VIA one saves/restores apparently fine but the ACPI _GTM methods break
on some platforms if we do this and this causes cable misdetections.
These are both effectively regressions as historically nothing matched the
devices and then decided not to bind to them. Nowdays something is binding
to all sorts of devices and a result they get dumped into D3.

For devices attached to the root bus, we can't trigger Secondary Bus
Reset because there is no bridge device associated with the bus. So
need to check bus->self again NULL first before using it.

In current code it continues setup even if alloc_msi_entry() for MSI-X
is failed due to lack of memory. It means arch_setup_msi_irqs() might
be called with msi_desc entries less than its argument nvec.
At least x86's arch_setup_msi_irqs() uses list_for_each_entry() for
dev->msi_list that suspected to have entries same numbers as nvec, and
it doesn't check the number of allocated vectors and passed arg nvec.
Therefore it will result in success of pci_enable_msix(), with less
vectors allocated than requested.
This patch fixes the error route to return -ENOMEM, instead of continuing
the setup (proposed by Matthew Wilcox).
Note that there is no iounmap in msi_free_irqs() if no msi_disc is
allocated.

Fix the code so that the zl10353 version of the Terratec Cinergy T XS USB
starts working again. This includes fixing what must have been a typo in the
GPIO definition for the digital side of the board, and setting of the
disable_i2c_gate_ctrl property for the zl10353 config, so that the i2c bus
doesn't get wedged the first time something tries to close the gate.
Also, add a printk() making clear that the mt352 version still isn't
supported. This issue is still being actively debugged, but in the meantime
at least the dmesg output will show a very clear error...

The original driver for Silvercrest cameras were using some values that
are different from what datasheet says. As result, it was taken very
less snapshots per second than expected.
A test with the datasheet values showed that they work fine and give a
better frame rate. So, let's stick with datasheet values.

Instead of working with a table of precalculated values, fill them with
the proper values. Also, adds format functions that allow changing the
resolution, by cropping the image to the center of the sensor.
While here, move the sensor version check to the probe routine, to
indicate to the caller if the sensor is not supported by this driver.
Also, fixes a stupid bug where we're using &buffer[] instead of
buffer[].

MT352 or ZL10353
Add DVB-T support for Yuan MPC-718 cards with an MT352 or ZL10353 demodulator.
There are apparently some units with a DiBcom demodulator which could be
supported by one of the dib7000 modules - but this is not implemented in the
cx18 driver (yet).
Due to lack of porgramming details for the MT352 and the mt352 module requiring
a "demod_init" function, a "firmware" must be obtained and loaded to get
DVB-T working for Yuan MPC-718 cards with an MT352.

precalculate_bars() improved vivi performance. However, it assumed that
always before streaming, the driver would call VIDIOC_S_STD. This is not
an API requirement, and the testing apps don't do that.
Due to that, a regression were caused by the patch that added it.
This patch moves the precalculate_bars to the proper place of the code,
calling it at buffer_prepare() callback.

Our current strategy for pass-through mode is to put all devices into
the 1:1 domain at startup (which is before we know what their dma_mask
will be), and only _later_ take them out of that domain, if it turns out
that they really can't address all of memory.
However, when there are a bunch of PCI devices behind a bridge, they all
end up with the same source-id on their DMA transactions, and hence in
the same IOMMU domain. This means that we _can't_ easily move them from
the 1:1 domain into their own domain at runtime, because there might be DMA
in-flight from their siblings.
So we have to adjust our pass-through strategy: For PCI devices not on
the root bus, and for the bridges which will take responsibility for
their transactions, we have to start up _out_ of the 1:1 domain, just in
case.
This fixes the BUG() we see when we have 32-bit-capable devices behind a
PCI-PCI bridge, and use the software identity mapping.
It does mean that we might end up using 'normal' mapping mode for some
devices which could actually live with the faster 1:1 mapping -- but
this is only for PCI devices behind bridges, which presumably aren't the
devices for which people are most concerned about performance.

At boot time, the dma_mask won't have been set on any devices, so we
assume that all devices will be 64-bit capable (and thus get a 1:1 map).

This should fix kernel.org bug #11821, where the dcdbas driver makes up
a platform device and then uses dma_alloc_coherent() on it, in an
attempt to get memory < 4GiB.

We need to give people a little more time to fix the broken drivers.
Re-introduce this, but tied in properly with the 'iommu=pt' support this
time. Change the config option name and make it default to 'no' too.

We do this twice, and it's about to get more complicated. This makes the
code slightly clearer about what it's doing, too.

When we reattach a device to the si_domain (because it's been removed
from a VM), we weren't calling domain_context_mapping() to actually tell
the hardware about that.
We should really put the call to domain_context_mapping() into
domain_add_dev_info() -- we never call the latter without also doing the
former, and we can keep the error paths simple that way. But that's a
cleanup which can wait for 2.6.32 now.

We should check iommu_dummy() _first_, because that means it's attached
to an iommu that we've just disabled completely. At the moment, we might
try to put the device into the identity mapping domain.

The aligned_nrpages() function rounds up to the next VM page, but
returns its result as a number of DMA pages.
Purely theoretical except on IA64, which doesn't boot with VT-d right
now anyway.

Increase the command ORB data structure to transport up to 16 bytes long
CDBs (instead of 12 bytes), and tell the SCSI mid layer about it. This
is notably necessary for READ CAPACITY(16) and friends, i.e. support of
large disks.

The DMA mapping API cannot map on-stack addresses, as explained in
Documentation/DMA-mapping.txt. Convert the two cases of on-stack packet
payload buffers in firewire-core (payload of lock requests in the bus
manager work and in iso resource management) to slab-allocated memory.
There are a number on-stack buffers for quadlet write or quadlet read
requests in firewire-core and firewire-sbp2. These are harmless; they
are copied to/ from card driver internal DMA buffers since quadlet
payloads are inlined with packet headers.

This way they'll be properly initialized early enough for users that may
touch them before the framebuffer has been registered.
Drivers that allocate their fb_info structure some other way (like
matrocfb's broken static allocation) need to be fixed up appropriately.

Correct the CLKVAL_F field value of VIDEO MAIN CONTROLLER 0 REGITSTER.
Frame Rate is 1 / [ { (VSPW+1) + (VBPD+1) + (LIINEVAL + 1) + (VFPD+1)
} x {(HSPW+1) + (HBPD +1)
+ (HFPD+1) + (HOZVAL + 1) } x { ( CLKVAL+1 ) / ( Frequency of Clock
source ) } ] and VCLK = Video Clock Source / (CLKVAL +1).
therefore CLKVAL_F should be "CLKVAL_F = Frequency of Clock source / pixel
clock * refresh".
for this, I added refresh value in platform data like below.
static struct s3c_fb_pd_win xxx_fb_win0 = {
/* this is to ensure we use win0 */
.win_mode = {
.refresh = 60,
.pixclock = (66+4+2+480)*(15+5+3+800),
.left_margin = 66,
.right_margin = 2,
.upper_margin = 15,
.lower_margin = 3,
.hsync_len = 4,
.vsync_len = 5,
.xres = 480,
.yres = 800,
},
.max_bpp = 32,
.default_bpp = 24,
};
static struct s3c_fb_platdata xxx_lcd_pdata __initdata = {
.win[0] = &xxx_fb_win0,
.vidcon0 = VIDCON0_VIDOUT_RGB | VIDCON0_PNRMODE_RGB,
.vidcon1 = VIDCON1_INV_HSYNC | VIDCON1_INV_VSYNC
| VIDCON1_INV_VCLK | VIDCON1_INV_VDEN,
.setup_gpio = s5pc1xx_fb_gpio_setup_24bpp,
};
xxx_machine_init()
{
.
.
.
s3c_fb_set_platdata(&xxx_lcd_pdata);
}
platform data defined in machine code should be setting using
s3c_fb_set_platdata().
