* hw/i386: fill in the CENTURY field of the FADT (FACP) ACPI tableLaszlo Ersek2016-01-081-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | NFIT is defined in ACPI 6.0: 5.2.25 NVDIMM Firmware Interface Table (NFIT) Currently, we only support PMEM mode. Each device has 3 structures: - SPA structure, defines the PMEM region info - MEM DEV structure, it has the @handle which is used to associate specified ACPI NVDIMM device we will introduce in later patch. Also we can happily ignored the memory device's interleave, the real nvdimm hardware access is hidden behind host - DCR structure, it defines vendor ID used to associate specified vendor nvdimm driver. Since we only implement PMEM mode this time, Command window and Data window are not needed The NVDIMM functionality is controlled by the parameter, 'nvdimm', which is introduced for the machine, there is a example to enable it: -machine pc,nvdimm -m 8G,maxmem=100G,slots=100 -object \ memory-backend-file,id=mem1,share,mem-path=/tmp/nvdimm1,size=10G -device \ nvdimm,memdev=mem1,id=nv1 It is disabled on default Reviewed-by: Stefan Hajnoczi <stefanha@redhat.com> Signed-off-by: Xiao Guangrong <guangrong.xiao@linux.intel.com> Reviewed-by: Michael S.

| | | | | | | | | | | | | | | | | | | | Read callbacks are now only invoked at item selection, before any data is read. As such, the value of the offset argument passed to the callback will always be 0. Also, the two callback instances currently in use both leave their offset argument unused. This patch removes the offset argument from the fw_cfg read callback prototype, and from the currently available instances. The unused (write) callback prototype is also removed (write support was removed earlier, in commit 023e3148).
