From 4ac45eb8d17c1a998182c302bd023ecb055bd9ee Mon Sep 17 00:00:00 2001 From: Mikko Perttunen Date: Wed, 2 Aug 2017 12:55:05 +0300 Subject: [PATCH] gpu: host1x: Fix bitshift/mask multipliers Some parts of Host1x uses BIT_WORD/BIT_MASK/BITS_PER_LONG to calculate register or field offsets. This worked fine on ARMv7, but now that BITS_PER_LONG is 64 but our registers are still 32-bit things are broken. Fix by replacing.. - BIT_WORD with (x / 32) - BIT_MASK with BIT(x % 32) - BITS_PER_LONG with 32 Signed-off-by: Mikko Perttunen Reviewed-by: Dmitry Osipenko Tested-by: Dmitry Osipenko Signed-off-by: Thierry Reding --- drivers/gpu/host1x/hw/intr_hw.c | 24 ++++++++++++------------ drivers/gpu/host1x/hw/syncpt_hw.c | 2 +- 2 files changed, 13 insertions(+), 13 deletions(-) diff --git a/drivers/gpu/host1x/hw/intr_hw.c b/drivers/gpu/host1x/hw/intr_hw.c index dacb8009a605..37ebb51703fa 100644 --- a/drivers/gpu/host1x/hw/intr_hw.c +++ b/drivers/gpu/host1x/hw/intr_hw.c @@ -33,10 +33,10 @@ static void host1x_intr_syncpt_handle(struct host1x_syncpt *syncpt) unsigned int id = syncpt->id; struct host1x *host = syncpt->host; - host1x_sync_writel(host, BIT_MASK(id), - HOST1X_SYNC_SYNCPT_THRESH_INT_DISABLE(BIT_WORD(id))); - host1x_sync_writel(host, BIT_MASK(id), - HOST1X_SYNC_SYNCPT_THRESH_CPU0_INT_STATUS(BIT_WORD(id))); + host1x_sync_writel(host, BIT(id % 32), + HOST1X_SYNC_SYNCPT_THRESH_INT_DISABLE(id / 32)); + host1x_sync_writel(host, BIT(id % 32), + HOST1X_SYNC_SYNCPT_THRESH_CPU0_INT_STATUS(id / 32)); schedule_work(&syncpt->intr.work); } @@ -50,9 +50,9 @@ static irqreturn_t syncpt_thresh_isr(int irq, void *dev_id) for (i = 0; i < DIV_ROUND_UP(host->info->nb_pts, 32); i++) { reg = host1x_sync_readl(host, HOST1X_SYNC_SYNCPT_THRESH_CPU0_INT_STATUS(i)); - for_each_set_bit(id, ®, BITS_PER_LONG) { + for_each_set_bit(id, ®, 32) { struct host1x_syncpt *syncpt = - host->syncpt + (i * BITS_PER_LONG + id); + host->syncpt + (i * 32 + id); host1x_intr_syncpt_handle(syncpt); } } @@ -117,17 +117,17 @@ static void _host1x_intr_set_syncpt_threshold(struct host1x *host, static void _host1x_intr_enable_syncpt_intr(struct host1x *host, unsigned int id) { - host1x_sync_writel(host, BIT_MASK(id), - HOST1X_SYNC_SYNCPT_THRESH_INT_ENABLE_CPU0(BIT_WORD(id))); + host1x_sync_writel(host, BIT(id % 32), + HOST1X_SYNC_SYNCPT_THRESH_INT_ENABLE_CPU0(id / 32)); } static void _host1x_intr_disable_syncpt_intr(struct host1x *host, unsigned int id) { - host1x_sync_writel(host, BIT_MASK(id), - HOST1X_SYNC_SYNCPT_THRESH_INT_DISABLE(BIT_WORD(id))); - host1x_sync_writel(host, BIT_MASK(id), - HOST1X_SYNC_SYNCPT_THRESH_CPU0_INT_STATUS(BIT_WORD(id))); + host1x_sync_writel(host, BIT(id % 32), + HOST1X_SYNC_SYNCPT_THRESH_INT_DISABLE(id / 32)); + host1x_sync_writel(host, BIT(id % 32), + HOST1X_SYNC_SYNCPT_THRESH_CPU0_INT_STATUS(id / 32)); } static int _host1x_free_syncpt_irq(struct host1x *host) diff --git a/drivers/gpu/host1x/hw/syncpt_hw.c b/drivers/gpu/host1x/hw/syncpt_hw.c index c93f74fcce72..7b0270d60742 100644 --- a/drivers/gpu/host1x/hw/syncpt_hw.c +++ b/drivers/gpu/host1x/hw/syncpt_hw.c @@ -89,7 +89,7 @@ static int syncpt_cpu_incr(struct host1x_syncpt *sp) host1x_syncpt_idle(sp)) return -EINVAL; - host1x_sync_writel(host, BIT_MASK(sp->id), + host1x_sync_writel(host, BIT(sp->id % 32), HOST1X_SYNC_SYNCPT_CPU_INCR(reg_offset)); wmb(); -- 2.20.1
