2018-05-28PcAtChipsetPkg/PcRtc: Add two new PCD for RTC Index/Target registersRuiyu Ni5-12/+25
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.

https://bugzilla.tianocore.org/show_bug.cgi?id=553 Remove left shift of negative values that always evaluate to 0 to address build errors from the llvm/clang compiler used in the XCODE5 tool chain. Clang rightfully complains about left-shifting ~DLAB. DLAB is #defined as 0x01 (an "int"), hence ~DLAB has value (-2) on all edk2 platforms. Left-shifting a negative int is undefined behavior. Rather than replacing ~DLAB with ~(UINT32)DLAB, realize that the nonzero bits of (~(UINT32)DLAB << 7) would all be truncated away in the final conversion to UINT8 anyway. So just remove (~DLAB << 7).

2017-03-06PcAtChipsetPkg: Refine casting expression result to bigger sizeHao Wu1-9/+9
There are cases that the operands of an expression are all with rank less than UINT64/INT64 and the result of the expression is explicitly cast to UINT64/INT64 to fit the target size. An example will be: UINT32 a,b; // a and b can be any unsigned int type with rank less than UINT64, like // UINT8, UINT16, etc. UINT64 c; c = (UINT64) (a + b); Some static code checkers may warn that the expression result might overflow within the rank of "int" (integer promotions) and the result is then cast to a bigger size. The commit refines codes by the following rules: 1). When the expression is possible to overflow the range of unsigned int/ int: c = (UINT64)a + b; 2). When the expression will not overflow within the rank of "int", remove the explicit type casts: c = a + b; 3). When the expression will be cast to pointer of possible greater size: UINT32 a,b; VOID *c; c = (VOID *)(UINTN)(a + b); --> c = (VOID *)((UINTN)a + b); 4). When one side of a comparison expression contains only operands with rank less than UINT32: UINT8 a; UINT16 b; UINTN c; if ((UINTN)(a + b) > c) {...} --> if (((UINT32)a + b) > c) {...} For rule 4), if we remove the 'UINTN' type cast like: if (a + b > c) {...} The VS compiler will complain with warning C4018 (signed/unsigned mismatch, level 3 warning) due to promoting 'a + b' to type 'int'.

2016-10-27PcAtChipsetPkg/HpetTimerDxe: Fix race condition in SetTimerPeriod()Michael Kinney1-2/+13
https://bugzilla.tianocore.org/show_bug.cgi?id=182 The function TimerDriverSetTimerPeriod() disables the HPET timer while the HPET timer HW is reprogrammed with a new timer period. However, the MMIO write to disable the HPET timer HW can be delayed and an HPET timer interrupt may be processed in the middle of reprogramming the HPET timer HW and this may produced unexpected results. The fix is to raise TPL to TPL_HIGH_LEVEL in TimerDriverSetTimerPeriod() during the time the HPET timer HW is reprogrammed. This guarantees that no timer interrupts are processed during reprogramming. The TimerDriverGenerateSoftInterrupt() function in this same driver also raises TPL to TPL_HIGH_LEVEL, so this fix matches the logic that is already used in another function for the same reason.

2015-12-22PcAtChipsetPkg/Rtc: Fix a UEFI Win7 boot hang issueRuiyu Ni4-4/+158
The patch updates the Century value in CMOS location specified by FADT.Century to avoid UEFI Win7 hang during booting. Per the ACPI spec if the FADT.Century is zero, it's not needed to store the century value in CMOS. But UEFI Win7 treats the Century storage is optional only when FADT.Century is 0x80. While Linux strictly follows the ACPI spec and treats Century storage is optional when FADT.Century is 0. So if a platform wants to support both UEFI Win7 and Linux, it needs to report FADT.Century to a traditional value which doesn't equal to 0 or 0x80 (0x32 mostly). And RTC driver is enhanced to save the century value to the location specified by FADT.Century.
