The ACPI specification (minimally versions 1.0b through 6.0) define the
FADT.CENTURY field as:
The RTC CMOS RAM index to the century of data value (hundred and
thousand year decimals). If this field contains a zero, then the RTC
centenary feature is not supported. If this field has a non-zero value,
then this field contains an index into RTC RAM space that OSPM can use
to program the centenary field.
The x86 targets generate ACPI payload, emulate an RTC
(CONFIG_MC146818RTC), and that RTC supports the "centenary feature" (see
occurrences of RTC_CENTURY in cmos_ioport_write() and cmos_ioport_read()
in "hw/timer/mc146818rtc.c".)
However, FADT.CENTURY is left at zero currently:
[06Ch 0108 1] RTC Century Index : 00
which -- according to analysis done by Ruiyu Ni at Intel -- should cause
Linux and Windows 8+ to think the RTC centenary feature is unavailable,
and cause Windows 7 to (incorrectly) assume that the offset to use is
constant 0x32. (0x32 happens to be the right value on QEMU, but Windows 7
is wrong to assume anything at all).
Exposing the right nonzero offset in FADT.CENTURY informs Linux and
Windows 8+ about the right capabilities of the hardware, plus it retrofits
our FADT to Windows 7's behavior.

In the current nvdimm_build_nfit(), the pointer 'header' initially equals
to table_data->data + table_data->len. However, the following
g_array_append_vals(table_data, structures->data, structures->len)
may resize and relocate table_data->data[]. Therefore, the usage of 'header'
afterwards may be illegal.
This patch fixes this issue by storing an offset within table_data->data[]
(rather than an address) in 'header'.

Current text_console_update() writes totally broken color attributes
to console_write_ch(). The format now is writing,
[WRONG]
bold << 21 | fg << 12 | bg << 8 | char
fg == 3bits curses color number
bg == 3bits curses color number
I can't see this format is where come from. Anyway, this doesn't work
at all.
What curses expects is actually (and vga.c is using),
[RIGHT]
bold << 21 | bg << 11 | fg << 8 | char
fg == 3bits vga color number
bg == 3bits vga color number
And curses set COLOR_PAIR() up to match this format, and curses's
chtype. I.e,
bold | color_pair | char
color_pair == (bg << 3 | fg)
To fix, this simply uses VGA color number everywhere except curses.c
internal. Then, convert it to above [RIGHT] format to write by
console_write_ch(). And as bonus, this reduces to expose curses define
to other parts (removes COLOR_* from console.c).
[Tested the first line is displayed as white on blue back for monitor
in curses console]

On overcommitted CPU, kernel can be so slow that an interrupt can
be triggered by the device whereas the driver is not ready to receive
it. This drives us into an infinite loop.
On suspend, if a SOF interrupt is raised between the stop of the
device processing and the change of the device internal state to
OHCI_USB_SUSPEND (QEMU stops SOF timer on this state change), this
interrupt is never acknowledged.
This patch clears pending SOF interrupt on OHCI_USB_SUSPEND setting.
Some details:
- ohci_irq(): the OHCI interrupt handler, acknowledges the SOF IRQ
only if the state of the driver (rh_state) is OHCI_STATE_RUNNING.
So if this interrupt happens and the driver is not in this state,
the function is called again and again, moving the system to a
CPU starvation.
- ohci_rh_suspend(): the function stop the operation and acknowledge
pending interrupts (but doesn't disable it). Later in the function,
the device is moved to OHCI_SUSPEND_STATE, and the driver to
OHCI_RH_SUSPENDED. If between the moment when the interrupt is
acknowledged and the moment when the device is suspended a new
interrupt is raised, it will be never acknowledged because the
driver is now not in OHCI_RH_RUNNING state.

On overcommitted CPU, kernel can be so slow that an interrupt can
be triggered by the device whereas the driver is not ready to receive
it. This drives us into an infinite loop.
This does not happen on real hardware because real hardware never send
interrupt immediately after the controller has been moved to OPERATION state.
This patch tries to delay the first SOF interrupt to let driver exits from
the critical section (which is not protected against interrupts...)
Some details:
- ohci_irq(): the OHCI interrupt handler, acknowledges the SOF IRQ
only if the state of the driver (rh_state) is OHCI_STATE_RUNNING.
So if this interrupt happens and the driver is not in this state,
the function is called again and again, moving the system to a
CPU starvation.
- ohci_rh_resume(): the driver re-enables operation with OHCI_USB_OPER.
In QEMU this start the SOF timer and QEMU starts to send IRQs. As
the driver is not in OHCI_STATE_RUNNING and not protected against IRQ,
the ohci_irq() can be called and the driver never moved to
OHCI_STATE_RUNNING.
