MdeModulePkg: Fix redundant call to RestoreTpl()

2024-09-04T00:53:54+00:00

Comments out a redundant call to RestoreTpl(). While this does not technically violate spec on raise/restore TPL, TPL should already be at the specified level. This extra call introduces an asymmetry between RaiseTpl and RestoreTpl calls, which makes analysis of TPL correctness more difficult and hampers certain non-standard TPL usages that some platforms require. Additionally, the two TPL variables were renamed to provide context for each of them. Signed-off-by: Kenneth Lautner

MdeModulePkg: Add extra RestoreTpl() call in DiskIo

2024-09-04T00:53:54+00:00

Adds a call to RestoreTpl() in DiskIo2ReadWriteDisk(). While the current implementation does not technically violate spec on raise/restore TPL, this extra call ensures symmetry between RaiseTpl and RestoreTpl calls, which makes analysis of TPL correctness simpler and permits certain non-standard TPL usages that some platforms require.

MdeModulePkg: Update code to be more C11 compliant by using func

2023-04-10T14:19:57+00:00

__FUNCTION__ is a pre-standard extension that gcc and Visual C++ among others support, while __func__ was standardized in C99. Since it's more standard, replace __FUNCTION__ with __func__ throughout MdeModulePkg. Signed-off-by: Rebecca Cran Reviewed-by: Michael D Kinney Reviewed-by: Ard Biesheuvel

MdeModulePkg/PartitionDxe: Add break to handle invalid LBA0 in MBR

2022-01-10T07:16:05+00:00

Read Disk does a modification of ExtMbrStartingLba with the code MultU64x32 (ExtMbrStartingLba, BlockSize) Error detection to see if ExtMbrStartingLBA has a value of 0. This is invalid as LBA 0 = MBR. After modification, the next time ExtMbrStartingLba is in this function if ExtMbrStartingLba is set to 0 in the MBR it never passes the while/do evaluation It is multiplied by 0 by read disk , set to 0 by an invalid MBR and goes back to evaluation This condition will also cause Ws19 and WS22 to hang, however Microsoft has developed a hotfix patch that will be released in 2022 Cc: Liming Gao Cc: Jian J Wang Cc: Hao A Wu Cc: Ray Ni Cc: Zhichao Gao Signed-off-by: Craig Edwards Reviewed-by: Hao A Wu
