2023-03-27PcAtChipsetPkg: Add PCD for RTC default yearMichael D Kinney1-0/+6
Add PcdRtcDefaultYear to specify the default year to use when the RTC is in an invalid state. Make sure PcdRtcDefaultYear is >= PcdMinimalValidYear and <= PcdMaximalValidYear. Set the default value for this PCD to PcdMinimalValidYear to preserve the existing behavior. A platform DSC file can override this default value setting.

2020-10-16PcAtChipsetPkg: Add MMIO Support to RTC driverSami Mujawar1-0/+16
Some virtual machine managers like Kvmtool emulate the MC146818 RTC controller in the MMIO space so that architectures that do not support I/O Mapped I/O can use the RTC. This patch adds MMIO support to the RTC controller driver. The PCD PcdRtcUseMmio has been added to select I/O or MMIO support. If PcdRtcUseMmio is: TRUE - Indicates the RTC port registers are in MMIO space. FALSE - Indicates the RTC port registers are in I/O space. Default is I/O space. Additionally two new PCDs PcdRtcIndexRegister64 and PcdRtcTargetRegister64 have been introduced to provide the base address for the RTC registers in the MMIO space. When MMIO support is selected (PcdRtcUseMmio == TRUE) the driver converts the pointers to the RTC MMIO registers so that the RTC registers are accessible post ExitBootServices.

PcdRealTimeClockUpdateTimeout is now defined in MdeModulePkg.dec. This is the only reason that causes PcAtChipsetPkg depends on MdeModulePkg. Move the PCD from MdeModulePkg.dec to PcAtChipsetPkg.dec removes such dependency.

2018-05-28PcAtChipsetPkg/PcRtc: Add two new PCD for RTC Index/Target registersRuiyu Ni1-1/+9
In certain HW implementation, the BIT7 of RTC Index register(0x70) is for NMI sources enable/disable but the BIT7 of 0x70 cannot be read before writing. Software which doesn't want to change the NMI sources enable/disable setting can write to the alias register 0x74, through which only BIT0 ~ BIT6 of 0x70 is modified. So two new PCDs are added so that platform can have the flexibility to change the default RTC register addresses from 0x70/0x71 to 0x74/0x75. With the new PCDs added, it can also support special HW that provides RTC storage in a different register pairs.

2015-06-11PcAtChipsetPkg/PcRtc: Fix a Y2K bugRuiyu Ni1-2/+3
The original driver cannot handle the case when system time runs from 1999/12/31 23:59:59 to 2000/1/1 0:0:0. A simple test to set system time to 1999/12/31 23:59:59 can expose this bug. The patch limits the driver to only support year in 100 range and decide the century value based on the supporting range: Century either equals to PcdMinimalYear / 100 or equals to PcdMinimalYear / 100 + 1. The patch passed the Y2K test. However with year range [1998, 2097], when system time is 2097/12/31 23:59:59, the next second system time will become 1998/1/1 0:0:0. I think it's a acceptable limitation.
