From: Prasad J Pandit <p...@fedoraproject.org> Hello,
In SDHCI protocol, the 'Block Count Enable' bit of the Transfer Mode register is used to control 's->blkcnt' value. This bit is not relevant in single block transfers. Also, Transfer Mode register value could be set such that 's->blkcnt' would not see an update during multi block transfers. Thus leading to an infinite loop. This patch set attempts to correct 'Block Count Enable' bit usage. This series incorporates changes suggested in patch set v3: -> https://lists.gnu.org/archive/html/qemu-devel/2017-02/msg02376.html -> https://lists.gnu.org/archive/html/qemu-devel/2017-02/msg02905.html Thank you. -- Prasad J Pandit (4): sd: sdhci: mask transfer mode register value sd: sdhci: check transfer mode register in multi block transfer sd: sdhci: conditionally invoke multi block transfer sd: sdhci: Remove block count enable check in single block transfers hw/sd/sdhci.c | 25 +++++++++++++------------ 1 file changed, 13 insertions(+), 12 deletions(-) -- 2.9.3
